1. To prevent electric shock, note the following

WARNING Before wiring and inspections, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier. Ground the servo amplifier and servo motor securely. Any person who is involved in wiring and inspection should be fully competent to do the work. Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, it may cause an electric shock. Do not operate switches with wet hands. Otherwise, it may cause an electric shock. The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric shock. During power-on or operation, do not open the front cover of the servo amplifier. Otherwise, it may cause an electric shock. Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging area are exposed and you may get an electric shock. Except for wiring and periodic inspection, do not remove the front cover of the servo amplifier even if the power is off. The servo amplifier is charged and you may get an electric shock. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo amplifier to the protective earth (PE) of the cabinet. To avoid an electric shock, insulate the connections of the power supply terminals.

2. To prevent fire, note the following

CAUTION Install the servo amplifier, servo motor, and regenerative resistor on incombustible material. Installing them directly or close to combustibles will lead to smoke or a fire. Always connect a magnetic contactor between the power supply and the main circuit power supply (L1/L2/L3) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the side of the servo amplifiers power supply. If a magnetic contactor is not connected, continuous flow of a large current may cause smoke or a fire when the servo amplifier malfunctions. Not doing so may cause a fire when a regenerative transistor malfunctions or the like may overheat the regenerative resistor. Always connect a molded-case circuit breaker, or a fuse to each servo amplifier between the power supply and the main circuit power supply (L1/L2/L3) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the side of the servo amplifiers power supply. If a molded-case circuit breaker or fuse is not connected, continuous flow of a large current may cause smoke or a fire when the servo amplifier malfunctions. When using the regenerative resistor, switch power off with the alarm signal. Provide adequate protection to prevent screws and other conductive matter, oil and other combustible matter from entering the servo amplifier and servo motor.

(3) Test run and adjustment

CAUTION When executing a test run, follow the notice and procedures in this instruction manual. Otherwise, it may cause a malfunction, damage to the machine, or injury. Before operation, check and adjust the parameter settings. Improper settings may cause some machines to operate unexpectedly. Never make a drastic adjustment or change to the parameter values as doing so will make the operation unstable. Do not get close to moving parts during the servo-on status.

(4) Usage

CAUTION Provide an external emergency stop circuit to stop the operation and shut the power off immediately. For equipment in which the moving part of the machine may collide against the load side, install a limit switch or stopper to the end of the moving part. The machine may be damaged due to a collision. Do not disassemble, repair, or modify the product. Otherwise, it may cause an electric shock, fire, injury, etc. Disassembled, repaired, and/or modified products are not covered under warranty. Before resetting an alarm, make sure that the run signal of the servo amplifier is off in order to prevent a sudden restart. Otherwise, it may cause an accident. Use a noise filter, etc., to minimize the influence of electromagnetic interference. Electromagnetic interference may affect the electronic equipment used near the servo amplifier. Do not burn or destroy the servo amplifier. Doing so may generate a toxic gas. Use the servo amplifier with the specified servo motor. Wire options and peripheral equipment, etc. correctly in the specified combination. Otherwise, it may cause an electric shock, fire, injury, etc. The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used for ordinary braking. For such reasons as incorrect wiring, service life, and mechanical structure (e.g. where a ball screw and the servo motor are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety, install a stopper on the machine side. If the dynamic brake is activated at power-off, alarm occurrence, etc., do not rotate the servo motor by an external force. Otherwise, it may cause a malfunction of the dynamic brake or a fire.

1. FUNCTIONS AND CONFIGURATION

POINT In MELSERVO-J4 series, ultra-small capacity servo amplifiers compatible with 48 V DC and 24 V DC power supplies are available as MR-J4-03A6(-RJ). Refer to chapter 18 for details of MR-J4-03A6(-RJ) servo amplifiers.

1.1 Summary

The Mitsubishi Electric MELSERVO-J4 series general-purpose AC servo has further higher performance and higher functions compared to the previous MELSERVO-J3 series. The MELSERVO-J4 series compatible rotary servo motor is equipped with 22-bit (4194304 pulses/rev) high- resolution absolute encoder. In addition, speed frequency response is increased to 2.5 kHz. Thus, faster and more accurate control is enabled as compared to the MELSERVO-J3 series. The servo amplifier has position, speed, and torque control modes. In the position control mode, the maximum pulse train of 4 Mpulses/s is supported. Further, it can perform operation with the control modes switched, e.g. position/speed control, speed/torque control and torque/position control. Hence, it is applicable to a wide range of fields, not only precision positioning and smooth speed control of machine tools and general industrial machines but also line control and tension control. With one-touch tuning and real-time auto tuning, you can automatically adjust the servo gains according to the machine. The tough drive function and the drive recorder function, which are well-received in the MELSERVO-JN series, have been improved. The MR-J4 servo amplifier supports the improved functions. Additionally, the preventive maintenance support function detects an error in the machine parts. This function provides strong support for the machine maintenance and inspection. The MR-J4-_A_ servo amplifier supports the STO (Safe Torque Off) function. By combining with optional MR-J3-D05, the servo amplifier supports SS1 (Safe Stop 1) function. The servo amplifier has a USB communication interface. Therefore, you can connect the servo amplifier to the personal computer with MR Configurator2 installed to perform the parameter setting, test operation, gain adjustment, and others. In the MELSERVO-J4 series, servo amplifiers with the CN2L connector are also available as MR-J4-_A_-RJ. By using the CN2L connector, an A/B/Z-phase differential output method external encoder can be connected to the servo amplifier. In a fully closed loop system, a four-wire type external encoder is connectable as well. The following table indicates the communication method of the external encoder compatible with the MR-J4- _A_ and MR-J4-_A_-RJ servo amplifiers.

Note 1. 0.5 A is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of

I/O points. 2. When closely mounting the servo amplifiers, operate them at the ambient temperature of 0 C to 45 C or at 75% or smaller

effective load ratio. 3. Test pulse is a signal which instantaneously turns off a signal to the servo amplifier at a constant period for external circuit to

self-diagnose. 4. Except for the terminal block. 5. The rated current is 2.9 A when the servo amplifier is used with a UL or CSA compliant servo motor. 6. 1 Mpulse/s or lower commands are supported in the initial setting. When inputting commands over 1 Mpulse/s and 4

Mpulses/s or lower, change the setting in [Pr. PA13]. 7. RS-422 communication is supported by servo amplifier with software version A3. 8. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does

not stop immediately but coasts at emergency stop. Ensure the safety in the entire equipment. 9. For the compatible version for the fully closed loop system, refer to table 1.1. 10. The MR-J4-_A servo amplifier is compatible only with the two-wire type.

The MR-J4-_A-RJ servo amplifier is compatible with the two-wire type, four-wire type, and A/B/Z-phase differential output method. Refer to table 1.1 for details.

11. This value is applicable when a 3-phase power supply is used. 12. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake

interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs.

13. RS-485 communication is available with servo amplifiers manufactured in November 2014 or later. 14. When using 1-phase 200 V AC to 240 V AC power supply, operate the servo amplifier at 75% or smaller effective load ratio. 15. The safety level depends on the setting value of [Pr. PF18 STO diagnosis error detection time] and whether STO input

diagnosis by TOFB output is performed or not. For details, refer to the Function column of [Pr. PF18] in section 5.2.6. 16. Follow the restrictions in section 2.6 when using this product at altitude exceeding 1000 m and up to 2000 m above sea level. 17. The DC power supply input is available only with MR-J4-_A-RJ servo amplifiers. For the connection example of the power

circuit when a DC input is used, refer to app. 13.

2. INSTALLATION

WARNING To prevent electric shock, ground each equipment securely.

CAUTION

Stacking in excess of the specified number of product packages is not allowed. Do not hold the front cover, cables, or connectors when carrying the servo amplifier. Otherwise, it may drop. Install the equipment on incombustible material. Installing it directly or close to combustibles will lead to a fire. Install the servo amplifier and the servo motor in a load-bearing place in accordance with the Instruction Manual. Do not get on or put heavy load on the equipment. Otherwise, it may cause injury. Use the equipment within the specified environment. For the environment, refer to section 1.3. Provide an adequate protection to prevent screws and other conductive matter, oil and other combustible matter from entering the servo amplifier. Do not block the intake and exhaust areas of the servo amplifier. Otherwise, it may cause a malfunction. Do not drop or apply heavy impact on the servo amplifiers and the servo motors. Otherwise, injury, malfunction, etc. may occur. Do not install or operate the servo amplifier which have been damaged or have any parts missing. When the equipment has been stored for an extended period of time, contact your local sales office. When handling the servo amplifier, be careful about the edged parts such as corners of the servo amplifier. The servo amplifier must be installed in the metal cabinet. Fumigants that are used to disinfect and protect wooden packaging from insects contain halogens (such as fluorine, chlorine, bromine, and iodine) cause damage if they enter our products. Please take necessary precautions to ensure that remaining materials from fumigant do not enter our products, or treat packaging with methods other than fumigation (heat method). Additionally, disinfect and protect wood from insects before packing products.

POINT

When pulling out CNP1, CNP2, and CNP3 connectors of 100 V class/600 W or lower 200 V class servo amplifier, pull out CN3 and CN8 connectors beforehand.

POINT

Close mounting is possible depending on the capacity of the servo amplifier. Refer to section 1.3 for availability of close mounting. When closely mounting multiple servo amplifiers, the servo amplifier on the right must have a larger depth than that on the left. Otherwise, the CNP1, CNP2, and CNP3 connectors cannot be removed.

Leave a large clearance between the top of the servo amplifier and the cabinet walls, and install a cooling fan to prevent the internal temperature of the cabinet from exceeding the environment. When mounting the servo amplifiers closely, leave a clearance of 1 mm between the adjacent servo amplifiers in consideration of mounting tolerances. In this case, keep the ambient temperature within 0 C to 45 C or use the servo amplifier with 75% or less of the effective load ratio.

(1) The way of clamping the cable must be fully examined so that bending stress and cable's own weight stress are not applied to the cable connection.

(2) For use in any application where the servo motor moves, fix the cables (encoder, power supply, and

brake) with having some slack from the connector connection part of the servo motor to avoid putting stress on the connector connection part. Use the optional encoder cable within the bending life range. Use the power supply and brake wiring cables within the bending life of the cables.

(3) Avoid any probability that the cable insulator might be cut by sharp chips, rubbed by a machine corner or

stamped by workers or vehicles. (4) For installation on a machine where the servo motor moves, the bending radius should be made as large

as possible. Refer to section 10.4 for the bending life.

2.4 Inspection items

WARNING

Before starting maintenance and/or inspection, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier. To avoid an electric shock, only qualified personnel should attempt inspections. For repair and parts replacement, contact your local sales office.

CAUTION Do not perform insulation resistance test on the servo amplifier. Otherwise, it may cause a malfunction. Do not disassemble and/or repair the equipment on customer side.

It is recommended that the following points periodically be checked. (1) Check for loose terminal block screws. Retighten any loose screws. (2) Check the cables and the like for scratches or cracks. Inspect them periodically according to operating

conditions especially when the servo motor is movable. (3) Check that the connector is securely connected to the servo amplifier. (4) Check that the wires are not coming out from the connector. (5) Check for dust accumulation on the servo amplifier. (6) Check for unusual noise generated from the servo amplifier. (7) Make sure that the emergency stop circuit operates properly such that an operation can be stopped

immediately and a power is shut off by the emergency stop switch.

2.5 Parts having service life

Service life of the following parts is listed below. However, the service life vary depending on operating methods and environment. If any fault is found in the parts, they must be replaced immediately regardless of their service life. For parts replacement, please contact your sales representative.

Part name Life guideline Smoothing capacitor 10 years

Relay Number of power-on, dynamic brake stop, and forced stop: 100,000 times Number of on and off for STO: 1,000,000 times

Cooling fan 10,000 hours to 30,000 hours (2 years to 3 years) Absolute position battery Refer to section 12.2.

(1) Smoothing capacitor

The characteristic of smoothing capacitor is deteriorated due to ripple currents, etc. The life of the capacitor greatly depends on ambient temperature and operating conditions. The capacitor will reach the end of its life in 10 years of continuous operation in air-conditioned environment (ambient temperature of 40 C or less).

(2) Relays

Contact faults occur due to contact wear arisen from switching currents. A relay will reach the end of its service life if the following actions are performed a total of 100,000 times: powering on the servo amplifier, inputting the dynamic brake stop, and inputting the forced stop; or if the following action is performed a total of 1,000,000 times: turning on or off STO during servo-off and servo motor stop. In addition, the service life of a relay may vary depending on the power supply capacity.

(3) Servo amplifier cooling fan

The cooling fan bearings reach the end of their life in 10,000 hours to 30,000 hours. Normally, therefore, the cooling fan must be replaced in a few years of continuous operation as a guideline. If unusual noise or vibration is found during inspection, the cooling fan must also be replaced. The life indicates under the yearly average ambient temperature of 40 C, free from corrosive gas, flammable gas, oil mist, dust and dirt.

3. SIGNALS AND WIRING

WARNING

Any person who is involved in wiring should be fully competent to do the work. Before wiring, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier. Ground the servo amplifier and servo motor securely. Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, it may cause an electric shock. The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric shock. To avoid an electric shock, insulate the connections of the power supply terminals.

CAUTION

Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly, resulting in injury. Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may occur. Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur. The surge absorbing diode installed to the DC relay for control output should be fitted in the specified direction. Otherwise, the emergency stop and other protective circuits may not operate.

POINT

When you use a linear servo motor, replace the following words in the left to the words in the right. Load to motor inertia ratio Load to motor mass ratio Torque Thrust (Servo motor) speed (Linear servo motor) speed

3.1 Input power supply circuit

CAUTION

Always connect a magnetic contactor between the power supply and the main circuit power supply (L1/L2/L3) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the side of the servo amplifiers power supply. If a magnetic contactor is not connected, continuous flow of a large current may cause a fire when the servo amplifier malfunctions. Use ALM (Malfunction) to switch main circuit power supply off. Not doing so may cause a fire when a regenerative transistor malfunctions or the like may overheat the regenerative resistor. Check the servo amplifier model, and then input proper voltage to the servo amplifier power supply. If input voltage exceeds the upper limit of the specification, the servo amplifier will break down. The servo amplifier has a built-in surge absorber (varistor) to reduce exogenous noise and to suppress lightning surge. Exogenous noise or lightning surge deteriorates the varistor characteristics, and the varistor may be damaged. To prevent a fire, use a molded-case circuit breaker or fuse for input power supply. Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction. The N- terminal is not a neutral point of the power supply. Incorrect wiring will cause a burst, damage, etc. When insulating the main circuit power supply (L1/L2/L3) and the control circuit power supply (L11/L21) of the servo amplifier using an isolation transformer, etc., connect between L1 and L11 and between L2 and L21 at equipotential.

POINT

EM2 has the same function as EM1 in the torque control mode. Connect the 1-phase 200 V AC to 240 V AC power supply to L1 and L3. One of the connecting destinations is different from MR-J3 Series Servo Amplifier's. When using MR-J4 as a replacement for MR-J3, be careful not to connect the power to L2. When using the MR-J4-_A-RJ servo amplifier with the DC power supply input, refer to app. 13.

Configure the wirings so that the main circuit power supply is shut off and SON (Servo-on) is turned off after deceleration to a stop due to an alarm occurring, enabled servo forced stop, etc. A molded-case circuit breaker (MCCB) must be used with the input cables of the main circuit power supply.

Note 1. Between P3 and P4 is connected by default. When using the power factor improving DC reactor, remove the short bar between P3 and P4. Refer to section 11.11 for details. Additionally, a power factor improving DC reactor and power factor improving AC reactor cannot be used simultaneously.

2. When using the regenerative option, refer to section 11.2. 3. For the encoder cable, use of the option cable is recommended. For selecting cables, refer to "Servo Motor

Instruction Manual (Vol. 3)". 4. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.9.3. 5. For connecting servo motor power wires, refer to "Servo Motor Instruction Manual (Vol. 3)". 6. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until

closure of contacts) of 80 ms or less. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn off the magnetic contactor.

7. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo amplifier.

8. When not using the STO function, attach the short-circuit connector came with a servo amplifier. 9. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit

breaker. (Refer to section 11.10.) 10. Connecting a servo motor for different axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction. 11. Stepdown transformer is required when the coil voltage of the magnetic contactor is 200 V class. 12. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience.

However, they can be configured by one. 13. Do not ground L11 and L21.

The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they

can be configured by one. 15. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does

not stop immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the safety in the entire equipment. For alarms for which the servo motor does not decelerate to stop, refer to chapter 8. For wiring of the external dynamic brake, refer to section 11.17.

16. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs.

Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo amplifier to the

protective earth (PE) of the cabinet. 2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will malfunction and will not output

signals, disabling EM2 (Forced stop 2) and other protective circuits. 3. The forced stop switch (normally closed contact) must be installed. 4. Supply 24 V DC 10% to interfaces from outside. The total current capacity is up to 500 mA. 500 mA is the value applicable

when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.9.2 (1) that gives the current value necessary for the interface. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they can be configured by one.

5. When starting operation, always turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end). (Normally closed contact)

6. ALM (Malfunction) turns on in normal alarm-free condition. When this signal (normally closed contact) is switched off (at occurrence of an alarm), the output of the programmable controller should be stopped by the sequence program.

7. The pins with the same signal name are connected in the servo amplifier. 8. This length applies to the command pulse train input in the differential line driver type. It is 2 m or less in the open-collector

type. 9. Use SW1DNC-MRC2-_. (Refer to section 11.7.) 10. Controller or parameter units can also be connected via the CN3 connector, enabling RS-422/RS-485 communication. Note

that using the USB communication function (CN5 connector) prevents the RS-422/RS-485 communication function (CN3 connector) from being used, and vice versa. They cannot be used together.

12. When not using the STO function, attach the short-circuit connector came with a servo amplifier. 13. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo

amplifier. 14. Plus and minus of the power of source interface are the opposite of those of sink interface. 15. CLEAR and CLEARCOM of source interface are interchanged to sink interface. 16. When a command cable for connection with the controller side malfunctions due to disconnection or noise, a position

mismatch can occur. To avoid position mismatch, it is recommended that Encoder A-phase pulse and Encoder B-phase pulse be checked.

3.3.2 Power-on sequence

POINT The voltage of analog monitor output, output signal, etc. may be unstable at power-on.

(1) Power-on procedure

1) Always use a magnetic contactor for the main circuit power supply wiring (L1/L2/L3) as shown in above section 3.1. Configure up an external sequence to switch off the magnetic contactor as soon as an alarm occurs.

2) Switch on the control circuit power supply (L11/L21) simultaneously with the main circuit power

supply or before switching on the main circuit power supply. If the main circuit power supply is not on, the display shows the corresponding warning. However, by switching on the main circuit power supply, the warning disappears and the servo amplifier will operate properly.

3) The servo amplifier receives the SON (Servo-on) 2.5 s to 3.5 s after the main circuit power supply

is switched on. Therefore, when SON (Servo-on) is switched on simultaneously with the main circuit power supply, the base circuit will switch on in about 2.5 s to 3.5 s, and the RD (Ready) will switch on in further about 5 ms, making the servo amplifier ready to operate. (Refer to (2) in this section.)

4) When RES (Reset) is switched on, the base circuit is shut off and the servo motor shaft coasts.

When the servo motor shaft is to be locked mechanically after positioning completion (stop), switching on the PC (Proportion control) upon positioning completion will suppress the unnecessary torque generated to compensate for a position shift. When the shaft is to be locked for a long time, switch on the PC (Proportion control) and TL (External torque limit selection) at the same time to make the torque less than the rated by TLA (Analog torque limit). Do not use PC (Proportional control) in the torque control. Doing so may cause the operation to be performed at a speed exceeding the speed limit value.

POINT When alarms not related to the forced stop function occur, control of motor deceleration cannot be guaranteed. (Refer to chapter 8.) In the torque control mode, the forced stop deceleration function is not available. Disable the forced stop deceleration function for a machine in which multiple axes are connected together, such as a tandem structure. If an alarm occurs with the forced stop deceleration function disabled, the servo motor will stop with the dynamic brake. Keep SON (Servo-on) on while EM2 (Forced stop 2) is off. If SON (Servo-on) is off, forced stop deceleration, base circuit shut-off delay time, and vertical axis freefall prevention do not function.

3.7.1 Forced stop deceleration function

When EM2 is turned off, dynamic brake will start to stop the servo motor after forced stop deceleration. During this sequence, the display shows [AL. E6 Servo forced stop warning]. During normal operation, do not use EM2 (Forced stop 2) to alternate stop and drive. The servo amplifier life may be shortened. (1) Connection diagram

3.7.2 Base circuit shut-off delay time function

The base circuit shut-off delay time function is used to prevent vertical axis from dropping at a forced stop (EM2 goes off) or alarm occurrence due to delay time of the electromagnetic brake. Use [Pr. PC16] to set the delay time between completion of EM2 (Forced stop 2) or activation of MBR (Electromagnetic brake interlock) due to an alarm occurrence, and shut-off of the base circuit. (1) Timing chart

When EM2 (Forced stop 2) turns off or an alarm occurs during driving, the servo motor will decelerate based on the deceleration time constant. MBR (Electromagnetic brake interlock) will turn off, and then after the delay time set in [Pr. PC16], the servo amplifier will be base circuit shut-off status.

3.7.3 Vertical axis freefall prevention function

The vertical axis freefall prevention function avoids machine damage by pulling up the shaft slightly like the following case. When the servo motor is used for operating vertical axis, the servo motor electromagnetic brake and the base circuit shut-off delay time function avoid dropping axis at forced stop. However, those functions may not avoid dropping axis a few m due to the backlash of the servo motor electromagnetic brake. The vertical axis freefall prevention function is performed when all of the following conditions are met.

The control mode is set to the position control mode. A value other than "0" is set in [Pr. PC54 Vertical axis freefall prevention compensation amount]. "Forced stop deceleration function selection" of [Pr. PA04] is set to "Forced stop deceleration function enabled (2 _ _ _ )". EM2 (Forced stop 2) turned off or an alarm occurred while the servo motor speed is zero speed or less. MBR (Electromagnetic brake interlock) is enabled in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47] while the base circuit shut-off delay time is set in [Pr. PC16].

PC16] in accordance with the travel distance ([Pr. PC54). Adjust it considering the freefall prevention compensation amount by checking the servo motor speed, torque ripple, etc.

3.7.4 Residual risks of the forced stop function (EM2)

(1) The forced stop function is not available for alarms that activate the dynamic brake when the alarms occur.

(2) When an alarm that activates the dynamic brake during forced stop deceleration occurs, the braking

distance until the servo motor stops will be longer than that of normal forced stop deceleration without the dynamic brake.

(3) If STO is turned off during forced stop deceleration, [AL. 63 STO timing error] will occur.

To deactivate an alarm, cycle the control circuit power, push the "SET" button in the current alarm window, or cycle the RES (Reset) However, the alarm cannot be deactivated unless its cause is removed. 3.8.1 When you use the forced stop deceleration function

CAUTION

Configure an electromagnetic brake circuit which is interlocked with an external emergency stop switch.

Servo motor

Electromagnetic brake

B U

RA

Contacts must be opened when ALM (Malfunction) or MBR (Electromagnetic brake interlock) turns off.

24 V DC

Contacts must be opened with the emergency stop switch.

The electromagnetic brake is provided for holding purpose and must not be used for ordinary braking. Before operating the servo motor, be sure to confirm that the electromagnetic brake operates properly. Do not use the 24 V DC interface power supply for the electromagnetic brake. Always use the power supply designed exclusively for the electromagnetic brake. Otherwise, it may cause a malfunction. When using EM2 (Forced stop 2), use MBR (Electromagnetic brake interlock) for operating the electromagnetic brake. Operating the electromagnetic brake without using MBR during deceleration to a stop will saturate servo motor torques at the maximum value due to brake torque of the electromagnetic brake. This can result in delay of the deceleration to a stop from a set value.

POINT

Refer to "Servo Motor Instruction Manual (Vol. 3)" for specifications such as the power supply capacity and operation delay time of the electromagnetic brake. Refer to "Servo Motor Instruction Manual (Vol. 3)" for the selection of a surge absorber for the electromagnetic brake.

Note the following when the servo motor with an electromagnetic brake is used.

1) The electromagnetic brake will operate when the power (24 V DC) turns off.

2) The status is base circuit shut-off during RES (Reset) on. When you use the motor in vertical axis system, use MBR (Electromagnetic brake interlock).

3) Turn off SON (Servo-on) after the servo motor stopped.

3.11 Grounding

WARNING Ground the servo amplifier and servo motor securely. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo amplifier to the protective earth (PE) of the cabinet.

The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending on the wiring and ground cable routing, the servo amplifier may be affected by the switching noise (due to di/dt and dv/dt) of the transistor. To prevent such a fault, refer to the following diagram and always ground. To conform to the EMC Directive, refer to "EMC Installation Guidelines".

Ensure to connect the wire to the PE terminal of the servo amplifier. Do not connect the wire directly to the grounding of the cabinet.

6. NORMAL GAIN ADJUSTMENT

POINT In the torque control mode, you do not need to make gain adjustment. Before making gain adjustment, check that your machine is not being operated at maximum torque of the servo motor. If operated over maximum torque, the machine may vibrate and may operate unexpectedly. In addition, make gain adjustment with a safety margin considering characteristic differences of each machine. It is recommended that generated torque during operation is under 90% of the maximum torque of the servo motor. When you use a linear servo motor, replace the following words in the left to the words in the right. Load to motor inertia ratio Load to motor mass ratio Torque Thrust (Servo motor) speed (Linear servo motor) speed For the vibration suppression control tuning mode, the setting range of [Pr. PB07] is limited. For the vibration suppression control tuning mode, the setting range of [Pr. PB07] is limited. Refer to section 7.1.5 (4) for details.

6.1 Different adjustment methods

6.1.1 Adjustment on a single servo amplifier

The following table shows the gain adjustment modes that can be set on a single servo amplifier. For gain adjustment, first execute "Auto tuning mode 1". If you are not satisfied with the result of the adjustment, execute "Auto tuning mode 2" and "Manual mode" in this order. (1) Gain adjustment mode explanation

This section explains the functions and adjustment using the servo amplifier with MR Configurator2.

Function Description Adjustment Machine analyzer With the machine and servo motor coupled,

the characteristic of the mechanical system can be measured by giving a random vibration command from a personal computer to the servo and measuring the machine response.

You can grasp the machine resonance frequency and determine the notch frequency of the machine resonance suppression filter.

6.2 One-touch tuning

POINT After the one-touch tuning is completed, "Gain adjustment mode selection" in [Pr. PA08] will be set to "2 gain adjustment mode 2 (_ _ _ 4)". To estimate [Pr. PB06 Load to motor inertia ratio/load to motor mass ratio], set "Gain adjustment mode selection" in [Pr. PA08] to "Auto tuning mode 1 (_ _ _ 1)". When executing the one-touch tuning, check the [Pr. PA21 One-touch tuning function selection] is "_ _ _ 1" (initial value). At start of the one-touch tuning, only when "Auto tuning mode 1 (_ _ _ 1)" or "2 gain adjustment mode 1 (interpolation mode) (_ _ _ 0)" of "Gain adjustment mode selection" is selected in [Pr. PA08], [Pr. PB06 Load to motor inertia ratio] will be estimated. The amplifier command method can be used with the servo amplifier with software version C1 or later and MR Configurator2 with software version 1.45X or later. When the one-touch tuning is executed in the amplifier command method, MR Configurator2 is required. For MR-J4-03A6(-RJ) servo amplifier, one-touch tuning by the amplifier command method is not available.

The one-touch tuning includes two methods: the user command method and the amplifier command method. (1) User command method

You can execute the one-touch tuning with MR Configurator2 or push buttons. The user command method performs one-touch tuning by inputting commands from outside the servo amplifier.

(2) Amplifier command method

You can execute the one-touch tuning with MR Configurator2. In the amplifier command method, when you simply input a travel distance (permissible travel distance) that collision against the equipment does not occur during servo motor driving, a command for the optimum tuning will be generated inside the servo amplifier to perform one-touch tuning.

1) User command method

It is recommended to input commands meeting the following conditions to the servo amplifier. If one-touch tuning is executed while commands which do not meet the conditions are inputted to the servo amplifier, the one-touch tuning error may occur.

Servo motor speed

Forward rotation 0 r/min Reverse rotation

One cycle time

Dwell time

Deceleration time constant

Travel distance

Acceleration time constant

Fig. 6.1 Recommended command for one-touch tuning in the user command method

Item Description

Travel distance Set 100 pulses or more in encoder unit. Setting less than 100 pulses will cause the one-touch tuning error "C004".

Servo motor speed Set 150 r/min (mm/s) or higher. Setting less than 150 r/min may cause the one-touch tuning error "C005".

Acceleration time constant Deceleration time constant

Set the time to reach 2000 r/min (mm/s) to 5 s or less. Set an acceleration time constant/deceleration time constant so that the acceleration/deceleration torque is 10% or more of the rated torque. The estimation accuracy of the load to motor inertia ratio is more improved as the acceleration/deceleration torque is larger, and the one-touch tuning result will be closer to the optimum value.

Dwell time Set 200 ms or more. Setting a smaller value may cause the one-touch tuning error "C004".

One cycle time Set 30 s or less. Setting over 30 s will cause the one-touch tuning error "C004".

2) Amplifier command method

Input a permissible travel distance. Input it in the load-side resolution unit for the fully closed loop control mode, and in the servo motor-side resolution unit for other control modes. In the amplifier command method, the servo motor will be operated in a range between "current value permissible travel distance". Input the permissible travel distance as large as possible within a range that the movable part does not collide against the machine. Inputting a small permissible travel distance decreases the possibility that the moving part will collide against the machine. However, the estimation accuracy of the load to motor inertia ratio may be lower, resulting in improper tuning. Also, executing the one-touch tuning in the amplifier command method will generate a command for the following optimum tuning inside the servo amplifier to start the tuning.

(c) One-touch tuning execution

POINT

For equipment in which overshoot during one-touch tuning is in the permissible level of the in-position range, changing the value of [Pr. PA25 One-touch tuning overshoot permissible level] will shorten the settling time and improve the response. When executing one-touch tuning in the amplifier command method, turn on EM2, LSP, and LSN. When you turn off EM2, LSP, and LSN during one-touch tuning, "C008" will be displayed at status in error code, and the one-touch tuning will be canceled. When setting LSP and LSN to automatic on, enable the check box "LSP, LSN auto ON" in the one-touch tuning window of MR Configurator2. When one-touch tuning is executed in the amplifier command method while magnetic pole detection is not being performed, magnetic pole detection will be performed, and then one-touch tuning will start after the magnetic pole detection is completed.

After the response mode is selected in (1) (b) in this section, clicking "Start" will start one-touch tuning. If "Start" is clicked while the servo motor stops, "C002" or "C004" will be displayed at status in error code. (Refer to (1) (e) in this section for error codes.)

Click "Start" with the amplifier command method selected in the servo-off, the servo-on will be automatically enabled, and the one-touch tuning will start. In the one-touch tuning by the amplifier command method, an optimum tuning command will be generated in the servo amplifier after servo- on. Then, the servo motor will reciprocate, and the one-touch tuning will be executed. After the tuning is completed or canceled, the servo amplifier will be the servo-off status. When the servo-on command is inputted from outside, the amplifier will be the servo-on status.

C001 Overshoot exceeded Overshoot amount is a value larger than the one set in [Pr. PA10 In-position range] and [Pr. PA25 One-touch tuning - Overshoot permissible level].

Increase the in-position range or overshoot permissible level.

C002 Servo-off during tuning The one-touch tuning was attempted in the user command method during servo-off. The servo amplifier will be servo-off status during one-touch tuning.

When executing one-touch tuning in the user command method, turn to servo-on, and then execute it. Prevent the servo amplifier from being the servo-off status during one-touch tuning.

C003 Control mode error 1. The one-touch tuning was attempted while the torque control mode was selected in the control modes.

Select the position control mode or speed control mode for the control mode, and then execute one-touch tuning. Do not change the control mode during the one-touch tuning. 2. During one-touch tuning, the control mode

was attempted to change from the position control mode to the speed control mode.

C004 Time-out 1. One cycle time during the operation has been over 30 s.

Set one cycle time during the operation (time from the command start to the next command start) to 30 s or less.

2. The command speed is slow. Set the servo motor speed to 100 r/min or higher. Error is less likely to occur as the setting speed is higher. When one-touch tuning by the amplifier command is used, set a permissible travel distance so that the servo motor speed is 100 r/min or higher. Set a permissible travel distance to two or more revolutions as a guide value to set the servo motor speed to 100 r/min.

3. The operation interval of the continuous operation is short.

Set the stop interval during operation to 200 ms or more. Error is less likely to occur as the setting time is longer.

C005 Load to motor inertia ratio misestimated

1. The estimation of the load to motor inertia ratio at one-touch tuning was a failure.

Drive the motor with meeting conditions as follows.

The acceleration time constant/deceleration time constant to reach 2000 r/min (mm/s) is 5 s or less. Speed is 150 r/min (mm/s) or higher. The load to servo motor (mass of linear servo motor's primary side or direct drive motor) inertia ratio is 100 times or less. The acceleration/deceleration torque is 10% or more of the rated torque.

2. The load to motor inertia ratio was not estimated due to an oscillation or other influences.

Set to the auto tuning mode that does not estimate the load to motor inertia ratio as follows, and then execute the one-touch tuning.

6.3 Auto tuning

6.3.1 Auto tuning mode

The servo amplifier has a real-time auto tuning function which estimates the machine characteristic (load to motor inertia ratio) in real time and automatically sets the optimum gains according to that value. This function permits ease of gain adjustment of the servo amplifier. (1) Auto tuning mode 1

The servo amplifier is factory-set to the auto tuning mode 1. In this mode, the load to motor inertia ratio of a machine is always estimated to set the optimum gains automatically. The following parameters are automatically adjusted in the auto tuning mode 1.

Parameter Symbol Name

PB06 GD2 Load to motor inertia ratio PB07 PG1 Model loop gain PB08 PG2 Position loop gain PB09 VG2 Speed loop gain PB10 VIC Speed integral compensation

POINT

The auto tuning mode 1 may not be performed properly if all of the following conditions are not satisfied.

The acceleration/deceleration time constant to reach 2000 r/min (mm/s) is 5 s or less. Speed is 150 r/min (mm/s) or higher. The load to servo motor (mass of linear servo motor's primary side or direct drive motor) inertia ratio is 100 times or less. The acceleration/deceleration torque is 10% or more of the rated torque.

Under operating conditions which will impose sudden disturbance torque during acceleration/deceleration or on a machine which is extremely loose, auto tuning may not function properly, either. In such cases, use the auto tuning mode 2 or manual mode to make gain adjustment.

(2) Auto tuning mode 2

Use the auto tuning mode 2 when proper gain adjustment cannot be made by auto tuning mode 1. Since the load to motor inertia ratio is not estimated in this mode, set the value of a correct load to motor inertia ratio in [Pr. PB06]. The following parameters are automatically adjusted in the auto tuning mode 2.

When a servo motor is accelerated/decelerated, the load to motor inertia ratio estimation section always estimates the load to motor inertia ratio from the current and speed of the servo motor. The results of estimation are written to [Pr. PB06 Load to motor inertia ratio]. These results can be confirmed on the status display screen of the MR Configurator2. If you have already known the value of the load to motor inertia ratio or failed to estimate, set "Gain adjustment mode selection" to "Auto tuning mode 2 (_ _ _ 2)" in [Pr. PA08] to stop the estimation (turning off the switch in above diagram), and set the load to motor inertia ratio ([Pr. PB06]) manually. From the preset load to motor inertia ratio ([Pr. PB06]) value and response ([Pr. PA09]), the optimum loop gains are automatically set on the basis of the internal gain table. The auto tuning results are saved in the EEP-ROM of the servo amplifier every 60 minutes since power-on. At power-on, auto tuning is performed with the value of each loop gain saved in the EEP-ROM being used as an initial value.

POINT If sudden disturbance torque is imposed during operation, the load to motor inertia ratio may be misestimated temporarily. In such a case, set "Gain adjustment mode selection" to "Auto tuning mode 2 (_ _ _ 2)" in [Pr. PA08] and then set the correct load to motor inertia ratio in [Pr. PB06]. When any of the auto tuning mode 1 and auto tuning mode settings is changed to the manual mode 2 setting, the current loop gains and load to motor inertia ratio estimation value are saved in the EEP-ROM.

6.3.3 Adjustment procedure by auto tuning

Since auto tuning is enabled before shipment from the factory, simply running the servo motor automatically sets the optimum gains that match the machine. Merely changing the response level setting value as required completes the adjustment. The adjustment procedure is as follows.

Auto tuning conditions are not satisfied? (Estimation of

load to motor inertia ratio is difficult.)

6.3.4 Response level setting in auto tuning mode

Set the response of the whole servo system by [Pr. PA09]. As the response level setting is increased, trackability to a command improves and settling time decreases, but setting the response level too high will generate vibration. Set a value to obtain the desired response level within the vibration-free range. If the response level setting cannot be increased up to the desired response because of machine resonance beyond 100 Hz, filter tuning mode selection in [Pr. PB01] or machine resonance suppression filter in [Pr. PB13] to [Pr. PB16], [Pr. PB46] to [Pr. PB51] may be used to suppress machine resonance. Suppressing machine resonance may allow the response level setting to increase. Refer to section 7.2 and 7.3 for settings of the adaptive tuning mode and machine resonance suppression filter.

7.1.1 Machine resonance suppression filter

POINT The machine resonance suppression filter is a delay factor for the servo system. Therefore, vibration may increase if you set an incorrect resonance frequency or set notch characteristics too deep or too wide. If the frequency of machine resonance is unknown, decrease the notch frequency from higher to lower ones in order. The optimum notch frequency is set at the point where vibration is minimal. A deeper notch has a higher effect on machine resonance suppression but increases a phase delay and may increase vibration. A wider notch has a higher effect on machine resonance suppression but increases a phase delay and may increase vibration. The machine characteristic can be grasped beforehand by the machine analyzer on MR Configurator2. This allows the required notch frequency and notch characteristics to be determined.

If a mechanical system has a unique resonance point, increasing the servo system response level may cause resonance (vibration or unusual noise) in the mechanical system. at that resonance frequency. Using the machine resonance suppression filter and adaptive tuning can suppress the resonance of the mechanical system. The setting range is 10 Hz to 4500 Hz.

7. SPECIAL ADJUSTMENT FUNCTIONS

(1) Function

The machine resonance suppression filter is a filter function (notch filter) which decreases the gain of the specific frequency to suppress the resonance of the mechanical system. You can set the gain decreasing frequency (notch frequency), gain decreasing depth and width.

7.1.2 Adaptive filter II

POINT The machine resonance frequency which adaptive filter II (adaptive tuning) can respond to is about 100 Hz to 2.25 kHz. As for the resonance frequency out of the range, set manually. When adaptive tuning is executed, vibration sound increases as an excitation signal is forcibly applied for several seconds. When adaptive tuning is executed, machine resonance is detected for a maximum of 10 seconds and a filter is generated. After filter generation, the adaptive tuning mode automatically shifts to the manual setting. Adaptive tuning generates the optimum filter with the currently set control gains. If vibration occurs when the response setting is increased, execute adaptive tuning again. During adaptive tuning, a filter having the best notch depth at the set control gain is generated. To allow a filter margin against machine resonance, increase the notch depth in the manual setting. Adaptive vibration suppression control may provide no effect on a mechanical system which has complex resonance characteristics. Adaptive tuning in the high accuracy mode is available with servo amplifiers with software version C5 or later. The frequency is estimated more accurately in the high accuracy mode compared to the standard mode. However, the tuning sound may be larger in the high accuracy mode.

(1) Function

Adaptive filter II (adaptive tuning) is a function in which the servo amplifier detects machine vibration for a predetermined period of time and sets the filter characteristics automatically to suppress mechanical system vibration. Since the filter characteristics (frequency, depth) are set automatically, you need not be conscious of the resonance frequency of a mechanical system.

7.1.3 Shaft resonance suppression filter

POINT This filter is set properly by default according to servo motor you use and load moment of inertia. It is recommended that [Pr. PB23] be set to "_ _ _ 0" (automatic setting) because changing "Shaft resonance suppression filter selection" in [Pr. PB23] or [Pr. PB17 Shaft resonance suppression filter] may lower the performance.

(1) Function

When a load is mounted to the servo motor shaft, resonance by shaft torsion during driving may generate a mechanical vibration at high frequency. The shaft resonance suppression filter suppresses the vibration. When you select "Automatic setting", the filter will be set automatically on the basis of the motor you use and the load to motor inertia ratio.

7.1.4 Low-pass filter

(1) Function When a ball screw or the like is used, resonance of high frequency may occur as the response level of the servo system is increased. To prevent this, the low-pass filter is enabled for a torque command as a default. The filter frequency of the low-pass filter is automatically adjusted to the value in the following equation.

Filter frequency ([rad/s]) = 1 + GD2 VG2

However, when an automatically adjusted value is smaller than VG2, the filter frequency will be the VG2 value. To set [Pr. PB18] manually, select "Manual setting (_ _ 1 _)" of "Low-pass filter selection" in [Pr. PB23].

POINT The function is enabled when "Gain adjustment mode selection" in [Pr. PA08] is "Auto tuning mode 2 (_ _ _ 2)", "Manual mode (_ _ _ 3)", or "2 gain adjustment mode 2 (_ _ _ 4)". The machine resonance frequency supported in the vibration suppression control tuning mode is 1.0 Hz to 100.0 Hz. As for the vibration out of the range, set manually. Stop the servo motor before changing the vibration suppression control-related parameters. Otherwise, it may cause an unexpected operation. For positioning operation during execution of vibration suppression control tuning, provide a stop time to ensure a stop after vibration damping. Vibration suppression control tuning may not make normal estimation if the residual vibration at the servo motor side is small. Vibration suppression control tuning sets the optimum parameter with the currently set control gains. When the response setting is increased, set vibration suppression control tuning again. When using the vibration suppression control 2, set "_ _ _ 1" in [Pr. PA24].

7. SPECIAL ADJUSTMENT FUNCTIONS

POINT When load-side vibration does not show up in servo motor-side vibration, the setting of the servo motor-side vibration frequency does not produce an effect. When the anti-resonance frequency and resonance frequency can be confirmed using the machine analyzer or external equipment, do not set the same value but set different values to improve the vibration suppression performance. The setting range of [Pr. PB19], [Pr. PB20], [Pr. PB52], and [Pr. PB53] varies, depending on the value in [Pr. PB07].

7.1.6 Command notch filter

POINT By using the advanced vibration suppression control II and the command notch filter, the load-side vibration of three frequencies can be suppressed. The frequency range of machine vibration, which can be supported by the command notch filter, is between 4.5 Hz and 2250 Hz. Set a frequency close to the machine vibration frequency and within the range. When [Pr. PB45 Command notch filter] is changed during the positioning operation, the changed setting is not reflected. The setting is reflected approximately 150 ms after the servo motor stops (after servo-lock).

(1) Function

Command notch filter has a function that lowers the gain of the specified frequency contained in a position command. By lowering the gain, load-side vibration, such as work-side vibration and base shake, can be suppressed. Which frequency to lower the gain and how deep to lower the gain can be set.

You can switch gains with the function. You can switch gains during rotation and during stop, and can use an input device to switch gains during operation. 7.2.1 Applications

The following shows when you use the function. (1) You want to increase the gains during servo-lock but decrease the gains to reduce noise during rotation. (2) You want to increase the gains during settling to shorten the stop settling time. (3) You want to change the gains using an input device to ensure stability of the servo system since the load

to motor inertia ratio varies greatly during a stop (e.g. a large load is mounted on a carrier).

7.3 Tough drive function

POINT Set enable/disable of the tough drive function with [Pr. PA20 Tough drive setting]. (Refer to section 5.2.1.)

This function makes the equipment continue operating even under the condition that an alarm occurs. The tough drive functions are the vibration tough drive and the instantaneous power failure tough drive. 7.3.1 Vibration tough drive function

This function prevents vibration by resetting a filter instantaneously when machine resonance occurs due to varied vibration frequency caused by machine aging. To reset the machine resonance suppression filters with the function, [Pr. PB13 Machine resonance suppression filter 1] and [Pr. PB15 Machine resonance suppression filter 2] should be set in advance. Set [Pr. PB13] and [Pr. PB15] as follows. (1) One-touch tuning execution (section 6.1) (2) Manual setting (section 4.2.2) The vibration tough drive function operates when a detected machine resonance frequency is within 30% for a value set in [Pr. PB13 Machine resonance suppression filter 1] or [Pr. PB15 Machine resonance suppression filter 2]. To set a detection level of the function, set sensitivity in [Pr. PF23 Vibration tough drive - Oscillation detection level].

POINT Resetting [Pr. PB13] and [Pr. PB15] by the vibration tough drive function is performed constantly. However, the number of write times to the EEPROM is limited to once per hour. The vibration tough drive function does not reset [Pr. PB46 Machine resonance suppression filter 3], [Pr. PB48 Machine resonance suppression filter 4], and [Pr.

7.3.2 Instantaneous power failure tough drive function

The instantaneous power failure tough drive function avoids [AL. 10 Undervoltage] even when an instantaneous power failure occurs during operation. When the instantaneous power failure tough drive activates, the function will increase the tolerance against instantaneous power failure using the electrical energy charged in the capacitor in the servo amplifier and will change an alarm level of [AL. 10 Undervoltage] simultaneously. The [AL. 10.1 Voltage drop in the control circuit power] detection time for the control circuit power supply can be changed by [Pr. PF25 SEMI-F47 function - Instantaneous power failure detection time]. In addition, [AL. 10.2 Voltage drop in the main circuit power] detection level for the bus voltage is changed automatically.

POINT MBR (Electromagnetic brake interlock) will not turn off during the instantaneous power failure tough drive. When selecting "Enabled (_ _ _ 1)" for "Torque limit function selection at instantaneous power failure" in [Pr. PA26], if an instantaneous power failure occurs during operation, you can save electric energy charged in the capacitor in the servo amplifier by limiting torque at acceleration. You can also delay the time until the occurrence of [AL. 10.2 Voltage drop in the main circuit power]. Doing this will enable you to set a longer time in [Pr. PF25 SEMI-F47 function - Instantaneous power failure detection time]. When the load of instantaneous power failure is large, [AL. 10.2] caused by the bus voltage drop may occur regardless of the set value of [Pr. PF25 SEMI-F47 function - Instantaneous power failure detection time]. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs. MR-J4-03A6(-RJ) servo amplifier is not compatible with instantaneous power failure tough drive. The setting range of [Pr. PF25 SEMI-F47 function - Instantaneous power failure detection time] differs depending on the software version of the servo amplifier as follows.

Software version C0 or earlier: Setting range 30 ms to 200 ms Software version C1 or later: Setting range 30 ms to 500 ms

To comply with SEMI-F47 standard, it is unnecessary to change the initial value (200 ms). When the instantaneous power failure time exceeds 200 ms, and if the instantaneous power failure voltage is less than 70 % of the rated input voltage, the power may be turned off normally even if a value larger than 200 ms is set in the parameter.

However, a back-up capacitor may be necessary for instantaneous power failure in the main circuit power supply depending on the power supply impedance and operating situation. Use a 3-phase for the input power supply of the servo amplifier. Using a 1-phase 100 V AC/200 V AC for the input power supply will not comply with SEMI-F47 standard. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs. Be sure to perform actual machine tests and detail checks for power supply instantaneous power failure of SEMI-F47 standard with your equipment. The MR-J4-03A6(-RJ) servo amplifier is not compatible with SEMI-F47 standard.

The following explains the compliance with "SEMI-F47 semiconductor process equipment voltage sag immunity test" of MR-J4 series. This function enables to avoid triggering [AL. 10 Undervoltage] using the electrical energy charged in the capacitor in case that an instantaneous power failure occurs during operation. (1) Parameter setting

Setting [Pr. PA20] and [Pr. PF25] as follows will enable SEMI-F47 function.

(a) The voltage will drop in the control circuit power at "Rated voltage 50% or less". After 200 ms, [AL.

Instantaneous maximum output means power which servo amplifier can output in maximum torque at rated speed. You can examine margins to compare the values of following conditions and instantaneous maximum output. Even if driving at maximum torque with low speed in actual operation, the motor will not drive with the maximum output. This can be handled as a margin. The following shows the conditions of tolerance against instantaneous power failure.

(a) Delta connection

For the 3-phase (L1/L2/L3) delta connection, an instantaneous power failure occurs in the voltage between a pair of lines (e.g. between L1 and L2) among voltages between three pairs of lines (between L1 and L2, L2 and L3, or L3 and L1).

(b) Star connection

For the 3-phase (L1/L2/L3/neutral point N) star connection, an instantaneous power failure occurs in the voltage between a pair of lines (e.g. between L1 and N) among voltages at six locations, between three pairs of lines (between L1 and L2, L2 and L3, or L3 and L1) and between one of the lines and the neutral point (between L1 and N, L2 and N, or L3 and N).

7.5 Model adaptive control disabled

POINT Change the parameters while the servo motor stops. When setting auto tuning response ([Pr. PA09]), change the setting value one by one to adjust it while checking operation status of the servo motor. This is used with servo amplifiers with software version B4 or later.

(1) Summary

The servo amplifier has a model adaptive control. The servo amplifier has a virtual motor model and drives the servo motor following the output of the motor model in the model adaptive control. At model adaptive control disabled, the servo amplifier drives the motor with PID control without using the model adaptive control. The following shows the available parameters at model adaptive control disabled.

Parameter Symbol Name

PB08 PG2 Position loop gain PB09 VG2 Speed loop gain PB10 VIC Speed integral compensation

(2) Parameter setting

Set [Pr. PB25] to "_ _ _ 2". (3) Restrictions

The following functions are not available at model adaptive control disabled.

Function Explanation

Forced stop deceleration function ([Pr. PA04])

Disabling the model adaptive control while the forced stop deceleration function is enabled, [AL. 37] will occur. The forced stop deceleration function is enabled at factory setting. Set [Pr. PA04] to "0 _ _ _" (Forced stop deceleration function disabled).

Vibration suppression control 1 ([Pr. PB02]/[Pr. PB19]/[Pr. PB20])

Vibration suppression control 2 ([Pr. PB02]/[Pr. PB52]/[Pr. PB53])

The vibration suppression control uses the model adaptive control. Disabling the model adaptive control will also disable the vibration suppression control.

Overshoot amount compensation ([Pr. PB12])

The overshoot amount compensation uses data used by the model adaptive control. Disabling the model adaptive control will also disable the overshoot amount compensation.

Super trace control ([Pr. PA22])

The super trace control uses the model adaptive control. Disabling the model adaptive control will also disable the super trace control.

7.6 Lost motion compensation function

POINT The lost motion compensation function is enabled only in the position control mode.

The lost motion compensation function corrects response delays (caused by a non-sensitive band due to friction, twist, expansion, and backlash) caused when the machine travel direction is reversed. This function contributes to improvement for protrusions that occur at a quadrant change and streaks that occur at a quadrant change during circular cutting. This function is effective when a high follow-up performance is required such as drawing an arc with an X-Y table.

(1) Parameter setting Setting [Pr. PE44] to [Pr. PE50] enables the lost motion compensation function.

(a) Lost motion compensation function selection ([Pr. PE48])

Select the lost motion compensation function.

(b) Lost motion compensation ([Pr. PE44]/[Pr. PE45]) Set the same value for the lost motion compensation for each of when the forward rotation switches to the reverse rotation and when the reverse rotation switches to the forward rotation. When the heights of protrusions differ depending on the travel direction, set the different compensation for each travel direction. Set a value twice the usual friction torque and adjust the value while checking protrusions.

(c) Torque offset ([Pr. PE47])

For a vertical axis, unbalanced torque occurs due to the gravity. Although setting the torque offset is usually unnecessary, setting unbalanced torque of a machine as a torque offset cancels the unbalanced torque. The torque offset does not need to be set for a machine not generating unbalanced torque. The torque offset cannot be used for linear servo motors and direct drive motors. Set 0.00%.

7 - 36

(d) Lost motion compensation timing ([Pr. PE49])

You can set the delay time of the lost motion compensation start timing with this parameter. When a protrusion occurs belatedly, set the lost motion compensation timing corresponding to the protrusion occurrence timing.

(e) Lost motion compensation non-sensitive band ([Pr. PE50])

When the travel direction reverses frequently around the zero speed, unnecessary lost motion compensation is triggered by the travel direction switching. By setting the lost motion compensation non-sensitive band, the speed is recognized as 0 when the fluctuation of the droop pulse is the setting value or less. This prevents unnecessary lost motion compensation. When the value of this parameter is changed, the compensation timing is changed. Adjust the value of Lost motion compensation timing ([Pr. PE49]).

(f) Lost motion filter setting ([Pr. PE46])

Changing the value of this parameter is usually unnecessary. When a value other than 0.0 ms is set in this parameter, the high-pass filter output value of the set time constant is applied to the compensation and lost motion compensation continues.

(2) Adjustment procedure of the lost motion compensation function

(a) Measuring the load current Measure the load currents during the forward direction feed and reverse direction feed with MR Configurator2.

(b) Setting the lost motion compensation

Calculate the friction torque from the measurement result of (2) (a) in this section and set a value twice the friction torque in [Pr. PE44] and [Pr. PE45] as lost motion compensation.

Friction torque [%] = 2

|(load current during feed in the forward rotation direction [%]) - (load current during feed in the reverse rotation direction [%])|

(c) Checking protrusions

Drive the servo motor and check that the protrusions are corrected.

7. SPECIAL ADJUSTMENT FUNCTIONS

7 - 37

(d) Adjusting the lost motion compensation

When protrusions still occur, the compensation is insufficient. Increase the lost motion compensation by approximately 0.5% until the protrusions are eliminated. When notches occur, the compensation is excessive. Decrease the lost motion compensation by approximately 0.5% until the notches are eliminated. Different values can be set as the compensation for each of when the forward rotation (CCW) switches to the reverse rotation (CW) and when the reverse rotation (CW) switches to the forward rotation (CCW).

Travel direction

(e) Adjusting the lost motion compensation timing When the machine has low rigidity, the speed loop gain is set lower than the standard setting value, or the servo motor is rotating at high speed, quadrant projections may occur behind the quadrant change points. In this case, you can suppress the quadrant projections by delaying the lost motion compensation timing with [Pr. PE49 Lost motion compensation timing]. Increase the setting value of [Pr. PE49] from 0 ms (initial value) by approximately 0.5 ms to adjust the compensation timing.

(f) Adjusting the lost motion compensation non-sensitive band When the lost motion is compensated twice around a quadrant change point, set [Pr. PE50 Lost motion compensation non-sensitive band]. Increase the setting value so that the lost motion is not compensated twice. Setting [Pr. PE50] may change the compensation timing. Adjust the lost motion compensation timing of (2) (e) in this section.

7.7 Super trace control

(1) Summary In the normal position control, droop pulses are generated against the position control command from the controller. Using the feed forward gain sets droop pulses at a constant speed to almost 0. However, droop pulses generated during acceleration/deceleration cannot be suppressed. With the ideal model in the servo amplifier, the super trace control enables to set constant speed and uniform acceleration/deceleration droop pulses to almost 0 that cannot be coped with by the feed forward gain.

(2) Adjustment procedure

POINT In the super trace control, droop pulses are near 0 during the servo motor control. Thus, the normal INP (In-position) may always be turned on. Be sure to set "INP (In-position) on condition selection" in [Pr. PD31] to " _ 1 _ _". When you use the super trace control, it is recommended that the acceleration time constant up to the rated speed be set to 1 s or more.

The following shows the adjustment procedure.

Step Operation

1 Execute the gain adjustment with one-touch tuning, auto tuning, etc. Refer to chapter 6 for details.

2 Change the setting of auto tuning mode to the manual mode ([Pr. PA08]: _ _ _ 3).

3 Change the setting of feed forward gain ([Pr. PB04]), and adjust that droop pulses will be 0 at a constant speed.

4 Set the setting of INP (In-position) on condition selection ([Pr. PD31]) to " _ 1 _ _".

5 Enable the super trace control. ([Pr. PA22]: _ _ 2 _)

6 Change the setting of model loop gain ([Pr. PB07]), and adjust droop pulses during acceleration/deceleration.

88888 Watchdog 8888._ Watchdog DB Note 1. After resolving the source of trouble, cool the equipment for approximately 30 minutes. 2. The following shows three stop methods of DB, EDB, and SD.

DB: Stops with dynamic brake. (Coasts for the servo amplifier without dynamic brake.) Coasts for MR-J4-03A6(-RJ). Note that EDB is applied when an alarm below occurs: [AL. 30.1], [AL. 32.2], [AL. 32.4], [AL. 51.1], [AL. 51.2]

EDB: Electronic dynamic brake stop (available with specified servo motors) Refer to the following table for the specified servo motors. The stop method for other than the specified servo motors will be DB.

Series Servo motor

HG-KR HG-KR053/HG-KR13/HG-KR23/HG-KR43 HG-MR HG-MR053/HG-MR13/HG-MR23/HG-MR43 HG-SR HG-SR51/HG-SR52 HG-AK HG-AK0136/HG-AK0236/HG-AK0336

SD: Forced stop deceleration

3. This is applicable when [Pr. PA04] is set to the initial value. The stop system of SD can be changed to DB using [Pr. PA04]. 4. The alarm can be canceled by setting as follows:

For the fully closed loop control: set [Pr. PE03] to "1 _ _ _". When a linear servo motor or direct drive motor is used: set [Pr. PL04] to "1 _ _ _".

5. Reset this while all the safety observation functions are stopped. 6. This alarm will occur only in the J3 compatibility mode.

10. CHARACTERISTICS

POINT For the characteristics of the linear servo motor and the direct drive motor, refer to sections 15.4 and 16.5.

10.1 Overload protection characteristics

An electronic thermal is built in the servo amplifier to protect the servo motor, servo amplifier and servo motor power wires from overloads. [AL. 50 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve shown in fig. 10.1 [AL. 51 Overload 2] occurs if the maximum current is applied continuously for several seconds due to machine collision, etc. Use the equipment on the left-hand side area of the continuous or broken line in the graph. For the system where the unbalanced torque occurs, such as a vertical axis system, the unbalanced torque of the machine should be kept at 70% or less of the rated torque. This servo amplifier has solid-state servo motor overload protection. (The servo motor overload current (full load current) is set on the basis of 120% rated current of the servo amplifier.)

10. CHARACTERISTICS

The following table shows combinations of each servo motor and graph of overload protection characteristics.

Characteristics e Note 1. If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo

motor stop status (servo-lock status) or in a 50 r/min or less low-speed operation status, the servo amplifier may malfunction regardless of the electronic thermal protection.

2. The load ratio ranging from 300% to 350% applies to the HG-KR servo motor. 3. The operation time at the load ratio of 300% to 400% applies when the maximum torque of HG-JR servo motor is increased to

400% of rated torque.

10.2 Power supply capacity and generated loss

(1) Amount of heat generated by the servo amplifier Table 10.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For thermal design of an enclosed type cabinet, use the values in the table in consideration for the worst operating conditions. The actual amount of generated heat will be intermediate between values at rated torque and servo-off according to the duty used during operation. When the servo motor is run at less than the rated speed, the power supply capacity will be smaller than the value in the table, but the servo amplifier's generated heat will not change.

regenerative option, refer to section 11.2. 3. This value is applicable when the servo amplifier is cooled by using the panel through attachment.

10. CHARACTERISTICS

(2) Heat dissipation area for an enclosed type cabinet

The enclosed type cabinet (hereafter called the cabinet) which will contain the servo amplifier should be designed to ensure that its temperature rise is within +10 C at the ambient temperature of 40 C. (With an approximately 5 C safety margin, the system should operate within a maximum 55 C limit.) The necessary cabinet heat dissipation area can be calculated by equation 10.1.

A = K P

T (10.1)

A P T K

: Heat dissipation area [m2] : Loss generated in the cabinet [W] : Difference between internal and ambient temperatures [C] : Heat dissipation coefficient [5 to 6]

When calculating the heat dissipation area with equation 10.1, assume that P is the sum of all losses generated in the cabinet. Refer to table 10.1 for heat generated by the servo amplifier. "A" indicates the effective area for heat dissipation, but if the cabinet is directly installed on an insulated wall, that extra amount must be added to the cabinet's surface area. The required heat dissipation area will vary with the conditions in the cabinet. If convection in the cabinet is poor and heat builds up, effective heat dissipation will not be possible. Therefore, arrangement of the equipment in the cabinet and the use of a cooling fan should be considered. Table 10.1 contains information on the required heat dissipation area (estimated) of servo amplifier cabinets when operating amplifiers at a rated load in ambient temperatures of 40 C.

(Outside the cabinet) (Inside the cabinet)

Air flow

Fig. 10.2 Temperature distribution in an enclosed type cabinet

When air flows along the outer wall of the cabinet, effective heat exchange will be possible, because the temperature slope inside and outside the cabinet will be steeper.

10.3 Dynamic brake characteristics

CAUTION

The coasting distance is a theoretically calculated value that does not consider factors such as friction. The calculated value will be longer than the actual distance. If the braking distance is not longer than the calculated value, a moving part may crash into the stroke end, causing a dangerous situation. Install an anti- crash mechanism such as an air brake or an electric/mechanical stopper such as a shock absorber to reduce the shock of moving parts.

POINT

Do not use dynamic brake to stop in a normal operation as it is the function to stop in emergency. For a machine operating at the recommended load to motor inertia ratio or less, the estimated number of usage times of the dynamic brake is 1000 times while the machine decelerates from the rated speed to a stop once in 10 minutes. Be sure to enable EM1 (Forced stop 1) after servo motor stops when using EM1 (Forced stop 1) frequently in other than emergency. Servo motors for MR-J4 may have the different coasting distance from that of the previous model. The electronic dynamic brake operates in the initial state for the HG series servo motors of 600 W or smaller capacity. The time constant "" for the electronic dynamic brake will be shorter than that of normal dynamic brake. Therefore, coasting distance will be longer than that of normal dynamic brake. For how to set the electronic dynamic brake, refer to [Pr. PF06] and [Pr. PF12].

10. CHARACTERISTICS

10.3.1 Dynamic brake operation

(1) Calculation of coasting distance Fig. 10.3 shows the pattern in which the servo motor comes to a stop when the dynamic brake is operated. Use equation 10.2 to calculate an approximate coasting distance to a stop. The dynamic brake time constant varies with the servo motor and machine operation speeds. (Refer to (2) (a), (b) in this section.) A working part generally has a friction force. Therefore, actual coasting distance will be shorter than a maximum coasting distance calculated with the following equation.

For 7 kW or lower servo amplifier, there is internal relay delay time of about 10 ms. For 11 kW to 22 kW servo amplifier, there is delay caused by magnetic contactor built into the external dynamic brake (about 50 ms) and delay caused by the external relay.

10.3.2 Permissible load to motor inertia when the dynamic brake is used

Use the dynamic brake under the load to motor inertia ratio indicated in the following table. If the load inertia moment is higher than this value, the dynamic brake may burn. If the load to motor inertia ratio exceeds the indicated value, contact your local sales office. The values of the permissible load to motor inertia ratio in the table are the values at the maximum rotation speed of the servo motor. The value in the parenthesis shows the value at the rated speed.

10.5 Inrush currents at power-on of main circuit and control circuit

POINT For a servo amplifier of 600 W or less, the inrush current values can change depending on frequency of turning on/off the power and ambient temperature.

A molded-case circuit breaker and magnetic contactor may fail or malfunction due to an inrush current flowing through the servo amplifier's power lines (input lines) at power on. Therefore, use products with the specifications as described. (Refer to section 11.10.) When circuit protectors are used, it is recommended that the inertia delay type, which is not tripped by an inrush current, be used. (1) 200 V class

The following shows the inrush currents (reference data) that will flow when 240 V AC is applied at the power supply capacity. When you use a 1-phase 200 V AC power supply with MR-J4-10A(-RJ) to MR- J4-200A(-RJ), the inrush currents of the main circuit power supply are the same.

11. OPTIONS AND PERIPHERAL EQUIPMENT

WARNING

Before connecting any option or peripheral equipment, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier.

CAUTION Use the specified auxiliary equipment and options to prevent a malfunction or a fire.

POINT

We recommend using HIV wires to wire the servo amplifiers, options, and peripheral equipment. Therefore, the recommended wire sizes may differ from those used for the previous servo amplifiers.

11.1 Cable/connector sets

POINT The IP rating indicated for cables and connectors is their protection against ingress of dust and raindrops when they are connected to a servo amplifier or servo motor. If the IP rating of the cable, connector, servo amplifier and servo motor vary, the overall IP rating depends on the lowest IP rating of all components.

Purchase the cable and connector options indicated in this section.

when rated (regenerative) torque is generated at rated speed. Efficiency varies with the speed and generated torque. Since the characteristics of the electrolytic capacitor change with time, allow for approximately 10% higher inverse efficiency.

Capacitor charging (Ec): Energy charged into the electrolytic capacitor in the servo amplifier

Subtract the capacitor charging from the result of multiplying the sum total of regenerative energies by the inverse efficiency to calculate the energy consumed by the regenerative option.

supplied regenerative resistor)

CAUTION

The regenerative resistor supplied with 11 kW to 22 kW servo amplifiers does not have a protective cover. Touching the resistor (including wiring/screw hole area) may cause a burn injury and electric shock. Even if the power was shut-off, be careful until the bus voltage discharged and the temperature decreased because of the following reasons.

It may cause a burn injury due to very high temperature without cooling. It may cause an electric shock due to charged capacitor of the servo amplifier.

Do not use servo amplifiers with external regenerative resistors other than the combinations specified below. Otherwise, it may cause a fire.

When using the regenerative resistors supplied to the servo amplifier, the specified number of resistors (4 or 5 resistors) must be connected in series. If they are connected in parallel or in less than the specified number, the servo amplifier may become faulty and/or the regenerative resistors burn. Install the resistors at intervals of about 70 mm. Cooling the resistors with two cooling fans (1.0 m3/min or more, 92 mm 92 mm) improves the regeneration capability. In this case, set "_ _ F A" in [Pr. PA02].

(Note) Series connection

5 m or shorter

Note. The number of resistors connected in series depends on the resistor type. The thermal sensor is not mounted on the attached regenerative resistor. An abnormal heating of resistor may be generated at a regenerative circuit failure. Install a thermal sensor near the resistor and establish a protective circuit to shut off the main circuit power supply when abnormal heating occurs. The detection level of the thermal sensor varies according to the settings of the resistor. Set the thermal sensor in the most appropriate position on your design basis, or use the thermal sensor built-in regenerative option. (MR-RB5R, MR-RB9F, MR-RB9T, MR-RB5K-4, or MR-RB6K-4)

11.3 FR-BU2-(H) Brake unit

POINT Use a 200 V class brake unit and a resistor unit with a 200 V class servo amplifier, and a 400 V class brake unit and a resistor unit with a 400 V class servo amplifier. Combination of different voltage class units cannot be used. When a brake unit and a resistor unit are installed horizontally or diagonally, the heat dissipation effect diminishes. Install them on a flat surface vertically. Temperature of the resistor unit case rises to higher than +100 C. Keep cables and flammable materials away from the case. Ambient temperature condition of the brake unit is between -10 C to 50 C. Note that the condition is different from the ambient temperature condition of the servo amplifier (between 0 C and 55 C). Configure the circuit to shut down the power-supply with the alarm output of the brake unit and the resistor unit under abnormal condition. Use the brake unit with a combination indicated in section 11.3.1. To perform continuous regenerative operation, use the FR-RC-(H) power regeneration converter, FR-CV-(H) power regeneration common converter, or FR-XC-(H) multifunction regeneration converter. Brake unit and regenerative options (Regenerative resistor) cannot be used simultaneously.

Connect the brake unit to the bus of the servo amplifier. As compared to the MR-RB regenerative option, the brake unit can return larger power. Use the brake unit when the regenerative option cannot provide sufficient regenerative capability. When using the brake unit, set [Pr. PA02] of the servo amplifier to "_ _ 0 1". When using the brake unit, always refer to the FR-BU2 Instruction Manual.

(5) Other precautions

(a) When using the FR-CV-(H), always install the dedicated stand-alone reactor (FR-CVL-(H)). Do not use the power factor improving AC reactor (FR-HAL-(H)) or Power factor improving DC reactor (FR- HEL-(H)).

(b) The inputs/outputs (main circuits) of the FR-CV-(H) and servo amplifiers include high-frequency

components and may provide electromagnetic wave interference to communication equipment (such as AM radios) used near them. In this case, interference can be reduced by installing the radio noise filter (FR-BIF(-H)) or line noise filter (FR-BSF01, FR-BLF).

(c) The overall wiring length for connection of the DC power supply between the FR-CV-(H) and servo

amplifiers should be 5 m or less, and the wiring must be twisted. (6) Specifications

11.11 Power factor improving DC reactors

The following shows the advantages of using power factor improving DC reactor. It improves the power factor by increasing the form factor of the servo amplifier's input current. It decreases the power supply capacity. The input power factor is improved to be about 85%. As compared to the power factor improving AC reactor (FR-HAL-(H)), it decreases the loss.

When connecting the power factor improving DC reactor to the servo amplifier, always disconnect P3 and P4. If it remains connected, the effect of the power factor improving DC reactor is not produced. When used, the power factor improving DC reactor generates heat. To release heat, therefore, leave a 10 cm or more clearance at each of the top and bottom, and a 5 cm or more clearance on each side.

The following shows the advantages of using power factor improving AC reactor. It improves the power factor by increasing the form factor of the servo amplifier's input current. It decreases the power supply capacity. The input power factor is improved to be about 80%.

When using power factor improving reactors for two servo amplifiers or more, be sure to connect a power factor improving reactor to each servo amplifier. If using only one power factor improving reactor, enough improvement effect of phase factor cannot be obtained unless all servo amplifiers are operated. (1) 200 V class/100 V class

11.14 Noise reduction techniques

Noises are classified into external noises which enter the servo amplifier to cause it to malfunction and those radiated by the servo amplifier to cause peripheral devices to malfunction. Since the servo amplifier is an electronic device which handles small signals, the following general noise reduction techniques are required. Also, the servo amplifier can be a source of noise as its outputs are chopped by high carrier frequencies. If peripheral devices malfunctions due to noises produced by the servo amplifier, noise suppression measures must be taken. The measures will vary slightly with the routes of noise transmission. (1) Noise reduction techniques

(a) General reduction techniques Avoid bundling power lines (input/output) and signal cables together or running them in parallel to each other. Separate the power lines from the signal cables. Use a shielded twisted pair cable for connection with the encoder and for control signal transmission, and connect the external conductor of the cable to the SD terminal. Ground the servo amplifier, servo motor, etc. together at one point. (Refer to section 3.11.)

(b) Reduction techniques for external noises that cause the servo amplifier to malfunction

If there are noise sources (such as a magnetic contactor, an electromagnetic brake, and many relays which make a large amount of noise) near the servo amplifier and the servo amplifier may malfunction, the following countermeasures are required.

Provide surge absorbers on the noise sources to suppress noises. Attach data line filters to the signal cables. Ground the shields of the encoder connecting cable and the control signal cables with cable clamp fittings. Although a surge absorber is built into the servo amplifier, to protect the servo amplifier and other equipment against large exogenous noise and lightning surge, attaching a varistor to the power input section of the equipment is recommended.

(c) Techniques for noises radiated by the servo amplifier that cause peripheral devices to malfunction

Noises produced by the servo amplifier are classified into those radiated from the cables connected to the servo amplifier and its main circuits (input and output circuits), those induced electromagnetically or statically by the signal cables of the peripheral devices located near the main circuit cables, and those transmitted through the power supply cables.

Noises produced by servo amplifier Noises transmitted in the air Noise radiated directly from servo amplifier

Noises transmitted through electric channels Noise transmitted through power supply cable

When measuring instruments, receivers, sensors, etc. which handle weak signals and may malfunction due to noise and/or their signal cables are contained in a cabinet together with the servo amplifier or run near the servo amplifier, such devices may malfunction due to noises transmitted through the air. The following techniques are required. 1. Provide maximum clearance between easily affected devices and the servo amplifier. 2. Provide maximum clearance between easily affected signal cables and the I/O cables of the servo

amplifier. 3. Avoid wiring the power lines (input/output lines of the servo amplifier) and signal lines side by side

or bundling them together. 4. Insert a line noise filter to the I/O cables or a radio noise filter on the input line. 5. Use shielded wires for the signal and power lines, or put the lines in separate metal conduits.

4) 5) 6)

When the power lines and the signal lines are laid side by side or bundled together, magnetic induction noise and static induction noise will be transmitted through the signal cables and malfunction may occur. The following techniques are required. 1. Provide maximum clearance between easily affected devices and the servo amplifier. 2. Provide maximum clearance between easily affected signal cables and the I/O cables of the servo

amplifier. 3. Avoid wiring the power lines (input/output lines of the servo amplifier) and signal lines side by side

or bundling them together. 4. Use shielded wires for the signal and power lines, or put the lines in separate metal conduits.

7)

When the power supply of peripheral equipment is connected to the power supply of the servo amplifier system, noises produced by the servo amplifier may be transmitted back through the power supply cable and the devices may malfunction. The following techniques are required. 1. Install the radio noise filter (FR-BIF(-H)) on the power lines (Input lines) of the servo amplifier. 2. Install the line noise filter (FR-BSF01/FR-BLF) on the power lines of the servo amplifier.

8) If the grounding wires of the peripheral equipment and the servo amplifier make a closed loop circuit, leakage current may flow through, causing the equipment to malfunction. In this case, the malfunction may be prevented by the grounding wires disconnected from the equipment.

(c) Cable clamp fitting AERSBAN-_SET

Generally, connecting the grounding of the shielded wire to the SD terminal of the connector provides a sufficient effect. However, the effect can be increased when the shielded wire is connected directly to the grounding plate as shown below. Install the grounding plate near the servo amplifier for the encoder cable. Peel part of the cable sheath to expose the external conductor, and press that part against the grounding plate with the cable clamp. If the cable is thin, clamp several cables in a bunch. The clamp comes as a set with the grounding plate.

(d) Line noise filter (FR-BSF01/ FR-BLF)

This filter is effective in suppressing noises radiated from the power supply side and output side of the servo amplifier and also in suppressing high-frequency leakage current (0-phase current). It especially affects the noises between 0.5 MHz and 5 MHz band.

Connection diagram Dimensions [Unit: mm]

The line noise filters can be mounted on lines of the main power supply (L1/L2/L3) and of the servo motor power (U/V/W). Pass each of the wires through the line noise filter an equal number of times in the same direction. For wires of the main power supply, the effect of the filter rises as the number of passes increases, but generally four passes would be appropriate. For the servo motor power lines, passes must be four times or less. Do not pass the grounding wire through the filter. Otherwise, the effect of the filter will drop. Wind the wires by passing through the filter to satisfy the required number of passes as shown in Example 1. If the wires are too thick to wind, use two or more filters to have the required number of passes as shown in Example 2. Place the line noise filters as close to the servo amplifier as possible for their best performance.

11.17 External dynamic brake

CAUTION

Use an external dynamic brake for a servo amplifier of MR-J4-11KA(-RJ) to MR- J4-22KA(-RJ) and MR-J4-11KA4(-RJ) to MR-J4-22KA4(-RJ). Failure to do so will cause an accident because the servo motor does not stop immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the safety in the entire equipment. For alarms for which the servo motor does not decelerate to stop, refer to chapter 8. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs.

POINT

EM2 has the same function as EM1 in the torque control mode. Configure up a sequence which switches off the magnetic contactor of the external dynamic brake after (or as soon as) SON (Servo-on) has been turned off at a power failure or a malfunction. For the braking time taken when the external dynamic brake is operated, refer to section 10.3. The external dynamic brake is rated for a short duration. Do not use it very frequently. When using the 400 V class external dynamic brake, the power supply voltage is restricted to 1-phase 380 V AC to 463 V AC (50 Hz/60 Hz). The external dynamic brake operates when an alarm or [AL. E6 Servo forced stop warning] occurs, STO (STO1, STO2) is turned off, or the power is turned off. Do not use external dynamic brake to stop in a normal operation as it is the function to stop in emergency. For a machine operating at the recommended load to motor inertia ratio or less, the estimated number of usage times of the external dynamic brake is 1000 times while the machine decelerates from the rated speed to a stop once in 10 minutes. Be sure to enable EM1 (Forced stop 1) after servo motor stops when using EM1 (Forced stop 1) frequently in other than emergency.

(1) Selection of external dynamic brake

The dynamic brake is designed to bring the servo motor to a sudden stop when a power failure occurs or the protective circuit is activated, and is built in the 7 kW or less servo amplifier. Since it is not built in the 11 kW or more servo amplifier, purchase it separately. Assign DB (Dynamic brake interlock) to any of CN1-22 to CN1-25, CN1-49, CN1-13, and CN1-14 pins in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47].

Note 1. Assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. 2. Refer to section 1.3 for the power supply specifications. 3. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop

deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn off the magnetic contactor.

4. Turn off EM2 when the main power circuit power supply is off. 5. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they

can be configured by one. 6. Between P3 and P4 is connected by default. When using the power factor improving DC reactor, remove the short bar

between P3 and P4. Refer to section 11.11 for details. Additionally, a power factor improving DC reactor and power factor improving AC reactor cannot be used simultaneously.

7. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs.

8. Install an overcurrent protection device (molded-case circuit breaker, fuse, or others) to protect the branch circuit. (Refer to section 11.10 and (1) in this section.)

11.19.2 Precautions

Set the FR-XC-(H) to the common bus regeneration mode by turning on switch 1 of the function selecting switch (SW2). Do not supply power to the main circuit power supply terminals (L1/L2/L3) of the servo amplifier. Doing so may fail the servo amplifier and the FR-XC-(H). Connect the polarities of the DC power supply between the FR-XC-(H) and the servo amplifier correctly. Failing to do so may fail the FR-XC-(H) and the servo amplifier. For 400 V, use the rated voltage and permissible fluctuation of the input power supply within the following range. Rated voltage: 3-phase 380 V to 480 V, 50 Hz/60 Hz Permissible fluctuation: 3-phase 323 V to 528 V, 50 Hz/60 Hz

11.19.3 Servo amplifier settings

When using the FR-XC-(H), set the parameters as follows. [Pr. PA02]: "_ _ 0 1" [Pr. PA04]: "0 _ _ _" [Pr. PC27]: "_ _ _ 1"

12. ABSOLUTE POSITION DETECTION SYSTEM

CAUTION

If [AL. 25 Absolute position erased] or [AL. E3 Absolute position counter warning] has occurred, always perform home position setting again. Otherwise, it may cause an unexpected operation. If [AL. 25], [AL. 92], or [AL. 9F] occurs due to such as short circuit of the battery, the MR-BAT6V1 battery can become hot. Use the MR-BAT6V1 battery with case to prevent getting burnt.

POINT

Refer to section 11.8 for the replacement procedure of the battery. There are four types of batteries, MR-BAT6V1SET, MR-BAT6V1BJ, MR- BAT6V1SET-A and MR-BT6VCASE available to construct the absolute position detection system. MR-BAT6V1BJ has the following advantages compared to other batteries.

You can disconnect the encoder cable from the servo amplifier. You can replace the battery with the control circuit power supply off.

When absolute position data is erased from the encoder, always execute home position setting before operation. The absolute position data of the encoder will be erased in the followings. Additionally, when the battery is used out of specification, the absolute position data can be erased. MR-BAT6V1SET , MR-BAT6V1SET-A and MR-BT6VCASE

The encoder cable was disconnected. The battery was replaced when the control circuit power supply was off.

MR-BAT6V1BJ A connector or cable was disconnected between the servo motor and battery. The battery was replaced with procedures other than those of (6) in section 11.8.3.

If the following parameters are changed, the home position will be erased at the next power-on. Execute the home position return again after power-on.

[Pr. PA06 Electronic gear numerator (command pulse multiplication numerator)] [Pr. PA07 Electronic gear denominator (command pulse multiplication denominator)] [Pr. PA14 Rotation direction selection/travel direction selection] [Pr. PT08 Home position return position data] [Pr. PT28 Number of stations per rotation]

12.1 Summary

12.1.1 Features

For normal operation, the encoder consists of a detector designed to detect a position within one revolution and a cumulative revolution counter designed to detect the number of revolutions. The absolute position detection system always detects the absolute position of the machine and keeps it battery-backed, independently of whether the programmable controller power is on or off. Therefore, once home position return is made at the time of machine installation, home position return is not needed when power is switched on thereafter. Even at a power failure or a malfunction, the system can be easily restored.

12. ABSOLUTE POSITION DETECTION SYSTEM

12.1.2 Restrictions

The system cannot be configured under the following conditions. Additionally, test operation cannot be performed in the absolute position detection system. To perform test operation, select incremental system in [Pr. PA03]. (1) Speed control mode and torque control mode (2) Control switch-over mode (position/speed, speed/torque, and torque/position) (3) Stroke-less coordinate system, e.g. rotary shaft, infinitely long positioning (4) Changing electronic gear after home position setting. (5) Using alarm code output. (6) Using incremental value command method ([Pr. PT01] = "_ _ _ 1").

To configure absolute position detection system in incremental value command method, specify the incremental value command with the sub function of the point table or the command in the program. For details, refer to 4.2.2 and 5.2.2 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual (Positioning Mode)".

12.5 Startup procedure

(1) Battery installation. Refer to section 12.2.

(2) Parameter setting

Set "_ _ _ 1" in [Pr. PA03] of the servo amplifier and switch power off, then on. (3) Resetting of [AL. 25 Absolute position erased]

After connecting the encoder cable, [AL. 25] occurs at first power-on. Turn off the power, then on to reset the alarm.

(4) Confirmation of absolute position data transfer

When SON is turned on, the absolute position data is transferred to the programmable controller. Transferring the proper absolute position data will trigger the followings.

(a) RD (Ready) turns on.

(b) The absolute position data ready contact of programmable controller turns on.

(c) The MR Configurator2 ABS data display window (refer to section 12.1.5) and programmable

controller side ABS data registers show the same value (at the home position address of 0). If any warning such as [AL. E5 ABS time-out warning] or programmable controller side transfer error occurs, refer to section 12.7 or chapter 8 and take corrective action.

(5) Home position setting

The home position must be set if.

(a) System set-up is performed;

(b) The servo amplifier has been changed;

(c) The servo motor has been changed; or

(d) [AL. 25 Absolute position erased] occurred.

In the absolute position detection system, the absolute position coordinates are made up by making home position setting at the time of system set-up. The motor shaft may operate unexpectedly if positioning operation is performed without home position setting. Always make home position setting before starting. For the home position setting method and types, refer to section 12.6.3.

12.6 Absolute position data transfer protocol

POINT After switching on ABSM, turn on SON. When the ABS transfer mode is off, turning on SON does not switch on the base circuit.

12.6.1 Data transfer procedure

Each time SON is turned on (when the power is switched on for example), the programmable controller reads the position data (present position) of the servo amplifier. Time-out monitoring is performed by the programmable controller.

12.6.2 Transfer method

The following shows a sequence how to turn on the base circuit while it is off state because SON is off, EM2 is off, or an alarm is occurring. In the absolute position detection system, every time SON is turned on, ABSM should always be turned on to read the current position in the servo amplifier to the controller. The servo amplifier transmits to the controller the current position latched when ABSM switches from off to on. At the same time, this data is set as a position command value inside the servo amplifier. Unless ABSM (ABS transfer mode) is turned on, the base circuit cannot be turned on. (1) At power-on

1) After the absolute position data is transmitted, RD turns on by ABSM-off. When RD is on, ABSM-

on is not received.

2) Even if SON is turned on before ABSM is turned on, the base circuit is not turned on until ABSM is turned on. If an alarm has occurred, ABSM is not received. ABSM allows data transmission even while a warning is occurring.

3) If ABSM is turned off during the ABS transfer mode, the ABS transfer mode is interrupted and

[AL. E5 ABS time-out warning] occurs. If SON is turned off, RES is turned on, and EM2 is turned off during the ABS transfer mode, [AL. E5 ABS time-out warning] occurs.

4) Note that if ABSM is turned on for a purpose other than absolute position data transmission, the

1) The programmable controller turns on ABSM and SON at the leading edge of the internal servo-

on.

2) In response to ABS transfer mode, the servo detects and calculates the absolute position and turns on ABST to notify the programmable controller that the servo is ready for data transmission.

3) After acknowledging that ABST is turned on, the programmable controller will turn on ABSR.

4) In response to ABSR, the servo outputs the lower 2 bits of the absolute position data and ABST

in the off state.

5) After acknowledging that ABST has been turned off, which implies that 2 bits of the absolute position data have been transmitted, the programmable controller reads the lower 2 bits of the absolute position data and then turns off ABSR.

6) The servo turns on ABST so that it can respond to the next request. Steps 3) to 6) are repeated

until 32-bit data and the 6-bit checksum have been transmitted.

7) After receiving of the checksum, the programmable controller confirms that the 19th ABST is turned on, and then turns off ABSM. If ABSM is turned off during data transmission, ABSM is interrupted and the [AL. E5 ABS time-out warning] occurs.

(c) Checksum

he checksum is the code which is used by the programmable controller to check for errors in the received absolute position data. The 6-bit checksum is transmitted following the 32-bit absolute position data. At the programmable controller, calculate the sum of the received absolute position data using the ladder program and compare it with the checksum code sent from the servo. The method of calculating the checksum is shown. Every time the programmable controller receives 2 bits of absolute position data, it adds the data to obtain the sum of the received data. The checksum is 6-bit data.

Example: absolute position data: -10 (FFFFFFF6H)

1) ABS request off-time time-out check (applied to 32-bit absolute position data in 2-bit units

(4) At the time of forced stop reset

(a) If the power is switched on in the forced stop state he forced stop state can be reset while the absolute position data is being transferred. If the forced stop state is reset while the absolute position data is transmitted, the base circuit is turned on 95 ms after resetting. If ABSM is off when the base circuit is turned on, RD is turned on 5 ms after the turning on of the base circuit. If ABSM is on when the base circuit is turned on, it is turned off and then RES is turned on. The absolute position data can be transmitted after the forced stop state is reset. The current position in the servo amplifier is updated even during an forced stop. When SON or ABSM are turned on during an forced stop as shown below, the servo amplifier transmits to the controller the current position latched when ABSM switches from off to on, and at the same time, the servo amplifier sets this data as a position command value. However, since the base circuit is off during a forced stop, the servo-lock status is not encountered. Therefore, if the servo motor is rotated by external force or the like after ABSM is turned on, this travel distance is accumulated in the servo amplifier as droop pulses. If the forced stop is cleared in this status, the base circuit turns on and the motor returns to the original position rapidly to compensate for the droop pulses. To avoid this status, reread the absolute position data before clearing the forced stop.

12.6.3 Home position setting

(1) Dog type home position return Preset a home position return creep speed at which the machine will not be given impact. On detection of a zero pulse, CR is turned from off to on. At the same time, the servo amplifier clears the droop pulses, comes to a sudden stop, and stores the stop position into the non-volatile memory as the home position absolute position data. CR should be turned on after it has been confirmed that INP is on. If this condition is not satisfied, [AL. 96 Home position setting warning] will occur, but that warning will be reset automatically by making home position return correctly. The number of home position setting times is limited to 1,000,000 times.

Move the machine to the position where the home position is to be set by performing manual operation such as JOG operation. When CR is on for longer than 20 ms, the stop position is stored into the non- volatile memory as the home position absolute position data. When the servo on, set CR to on after confirming that INP is on. If this condition is not satisfied, [AL. 96 Home position setting warning] will occur, but that warning will be reset automatically by making home position return correctly.

The timing charts at power on/off and SON on/off are given below. Preset [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47] of the servo amplifier to enable MBR. When MBR is set for the CN1-23 pin, turning ABSM on will change the CN1-23 pin to ABSB1 (ABS transmission data bit 1). Therefore, configure an external sequence to generate the electromagnetic brake torque as soon as ABSM and MBR turn off.

12.6.5 How to process the absolute position data at detection of stroke end

The servo amplifier stops the acceptance of the command pulse when off of LSP or LSN are detected, clears the droop pulses to 0 at the same time, and stops the servo motor. At this time, the programmable controller keeps outputting the command pulse. Since this causes a discrepancy between the absolute position data of the servo amplifier and the programmable controller, position mismatch will occur if the operation is continued. To prevent this difference in position data from occurring, do as described below. When the servo amplifier has detected the stroke end, perform JOG operation or the like to clear the stroke end. After that, switch SON off once, then on again, or switch the power off once, then on again. This causes the absolute position data of the servo amplifier to be transferred to the programmable controller, restoring the normal data. 12.7 Absolute position data transfer errors

POINT When the following alarm or warning occurs, refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)" to remove the failure.

12.8.1 Serial communication command

The following commands are available for reading absolute position data using the serial communication function. When reading data, take care to specify the correct station number of the servo amplifier from where the data will be read. When the master station sends the data No. to the slave station (servo amplifier), the slave station returns the data value to the master station. (1) Transmission

Transmit command [0] [2] and data No. [9] [1]. (2) Reply

13. USING STO FUNCTION

13 - 1

13. USING STO FUNCTION

POINT In the torque control mode, the forced stop deceleration function is not available. The MR-J4-03A6(-RJ) servo amplifier is not compatible with the STO function.

13.1 Introduction

This section provides the cautions of the STO function. 13.1.1 Summary

This servo amplifier complies with the following safety standards. ISO/EN ISO 13849-1:2015 Category 3 PL e IEC 61508 SIL 3 IEC/EN 61800-5-2 IEC/EN 62061 SIL CL3

13.1.2 Terms related to safety

The STO function shuts down energy to servo motors, thus removing torque. This function electronically cuts off power supply in the servo amplifier. The purpose of this function is as follows. (1) Uncontrolled stop according to stop category 0 of IEC/EN 60204-1 (2) Preventing unexpected start-up 13.1.3 Cautions

The following basic safety notes must be read carefully and fully in order to prevent injury to persons or damage to property. Only qualified personnel are authorized to install, start-up, repair, or service the machines in which these components are installed. They must be familiar with all applicable local regulations and laws in which machines with these components are installed, particularly the standards mentioned in this manual. The staff responsible for this work must be given express permission from the company to perform start-up, programming, configuration, and maintenance of the machine in accordance with the safety standards.

WARNING Improper installation of the safety related components or systems may cause improper operation in which safety is not assured, and may result in severe injuries or even death.

Protective Measures

This servo amplifier satisfies the Safe Torque Off (STO) function described in IEC/EN 61800-5-2 by preventing the energy supply from the servo amplifier to the servo motor. If an external force acts upon the drive axis, additional safety measures, such as brakes or counterbalances must be used.

13. USING STO FUNCTION

13 - 2

13.1.4 Residual risks of the STO function

Machine manufacturers are responsible for all risk evaluations and all associated residual risks. Below are residual risks associated with the STO function. Mitsubishi Electric is not liable for any damages or injuries caused by these risks. (1) The STO function disables energy supply to the servo motor by electrical shut-off. The function does not

mechanically disconnect electricity from the motor. Therefore, it cannot prevent exposure to electric shock. To prevent an electric shock, install a magnetic contactor or a molded-case circuit breaker to the main circuit power supply (L1/L2/L3) of the servo amplifier.

(2) The STO function disables energy supply to the servo motor by electrical shut-off. It does not guarantee

stop control or deceleration control of the servo motor. (3) For proper installation, wiring, and adjustment, thoroughly read the manual of each individual safety

related component. (4) In the safety circuit, use components that are confirmed safe or meet the required safety standards. (5) The STO function does not guarantee that the drive part of the servo motor will not rotate due to external

or other forces. (6) Safety is not assured until safety-related components of the system are completely installed or adjusted. (7) When replacing this servo amplifier, confirm that the model name of servo amplifiers are exactly the

same as those being replaced. Once installed, make sure to verify the performance of the functions before commissioning the system.

(8) Perform all risk assessments to the machine or the whole system. (9) To prevent accumulation of malfunctions, perform malfunction checks at regular intervals based on the

risk assessments of the machine or the system. Regardless of the system safety level, malfunction checks should be performed at least once per year.

(10) If the upper and lower power module in the servo amplifier are shorted and damaged simultaneously,

the servo motor may make a half revolution at a maximum. (11) The STO input signals (STO1 and STO2) must be supplied from one power source. Otherwise, the

STO function may not function properly due to a sneak current, failing to bring the STO shut-off state. (12) For the STO I/O signals of the STO function, supply power by using a safety extra low voltage (SELV)

power supply with the reinforced insulation.

If STO is turned off during operation, the servo motor is in dynamic brake stop (stop category 0), and [AL. 63 STO timing error] will occur.

13.3.1 Connection example for CN8 connector

This servo amplifier is equipped with the connector (CN8) in accordance with the STO function. When this connector is used with a certified external safety relay, power to the motor can be safely removed and unexpected restart can be prevented. The safety relay used should meet the applicable safety standards and have forcibly guided or mirror contacts for the purpose of error detection. In addition, the MR-J3-D05 safety logic unit can be used instead of a safety relay for implementation of various safety standards. Refer to app. 5 for details. The following diagram is for source interface. For sink interface, refer to section 13.4.1.

14.3.5 Time-out processing

The master station transmits EOT when the slave station does not start return processing (STX is not received) 300 [ms] after the master station has ended communication processing. 100 ms after that, the master station retransmits the message. Time-out occurs if the slave station does not answer after the master station has performed the above communication processing three times. (communication error)

14.3.6 Retry processing

When a fault occurs in communication between the master and slave stations, the error code in the response data from the slave station is a negative response code ([B] to [F], [b] to [f]). In this case, the master station retransmits the message which was sent at the occurrence of the fault (retry processing). A communication error occurs if the above processing is repeated and results in the error three or more consecutive times.

Similarly, when the master station detects a fault (e.g. checksum, parity) in the response data from the slave station, the master station retransmits the message which was sent at the occurrence of the fault. A communication error occurs if the retry processing is performed three times. 14.3.7 Initialization

After the slave station is switched on, it cannot return to communication until the internal initialization processing terminates. Hence, at power-on, ordinary communication should be started after. (1) Wait for 3.5 s or longer after the slave station is switched on. (2) Check that normal communication can be made by reading the parameter or other data which does not

pose any safety problems.

14.5 Detailed explanations of commands

14.5.1 Data processing

When the master station transmits a command data No. or a command + data No. + data to a slave station, the servo amplifier returns a response or data in accordance with the purpose. When numerical values are represented in these send data and receive data, they are represented in decimal, hexadecimal, etc. Therefore, data must be processed in accordance with the application. Since whether data must be processed or not and how to process data depend on the monitoring, parameters, etc., follow the detailed explanation of the corresponding command. The following methods are how to process send and receive data when reading and writing data. (1) Processing a read data

When the display type is 0, the eight-character data is converted from hexadecimal to decimal and a decimal point is placed according to the decimal point position information. When the display type is 1, the eight-character data is used unchanged.

The following example indicates how to process the receive data "003000000929" given to show. The receive data is as follows.

0 0 3 0 0 0 0 0 0 9 2 9

Display type 0: Data must be converted into decimal. 1: Data is used unchanged in hexadecimal.

Decimal point position 0: No decimal point 1: First least significant digit (normally not used) 2: Second least significant digit 3: Third least significant digit 4: Forth least significant digit 5: Fifth least significant digit 6: Sixth least significant digit

Data 32-bit length (hexadecimal representation) (Data conversion is required as indicated in the display type.)

Since the display type is "0" in this case, the hexadecimal data is converted into decimal. 00000929H 2345 As the decimal point position is "3", a decimal point is placed in the third least significant digit. Hence, "23.45" is displayed.

(2) Writing processed data

When the data to be written is handled as decimal, the decimal point position must be specified. If it is not specified, the data cannot be written. When the data is handled as hexadecimal, specify "0" as the decimal point position. The data to be sent is the following value.

Decimal point position 0: No decimal point 1: First least significant digit 2: Second least significant digit 3: Third least significant digit 4: Forth least significant digit 5: Fifth least significant digit

0 Data is transferred in hexadecimal.

For example, here is described how to process the set data when a value of "15.5" is sent. Since the decimal point position is the second least significant digit, the decimal point position data is "2". As the data to be sent is hexadecimal, the decimal data is converted into hexadecimal. 155 9B Hence, "0200009B" is transmitted.

(7) Writing setting values

POINT If setting values need to be changed with a high frequency (i.e. one time or more per one hour), write the setting values to the RAM, not the EEP-ROM. The EEPROM has a limitation in the number of write times and exceeding this limitation causes the servo amplifier to malfunction. Note that the number of write times to the EEP-ROM is limited to approximately 100, 000.

Write the parameter setting into EEP-ROM of the servo amplifier. Specify a parameter group in advance. (Refer to (1) in this section.) Write any value within the setting enabled range. For the setting enabled range, refer to chapter 5 or read the setting range by performing operation in (4) in this section. Transmit command [9] [4], the data No. , and the set data. The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value corresponds to the parameter No. When the data to be written is handled as decimal, the decimal point position must be specified. If it is not specified, the data cannot be written. When the data is handled as hexadecimal, specify "0" as the decimal point position. Check the writing data is within the upper/lower limit value before writing. To prevent an error, read the parameter data to be written, confirm the decimal point position, and create transmission data. On completion of writing, read the same parameter data to verify that data has been written correctly.

14.5.8 Test operation mode

POINT The test operation mode is used to check operation. Do not use it for actual operation. If communication stops for longer than 0.5 s during test operation, the servo amplifier decelerates to a stop, resulting in servo-lock. To prevent this, continue communication all the time by monitoring the status display, etc. Even during operation, you can switch the servo amplifier to the test operation mode. In this case, switching to the test operation mode will shut off the base circuit to coast the motor.

WARNING When using the linear servo motor, read "Linear Servo Motor Instruction Manual" and "Linear Encoder Instruction Manual".

POINT

The linear servo system is available for the servo amplifiers of which software version is A5 or later. The MR-J4-03A6(-RJ) servo amplifier is not compatible with linear servo motor.

15.1 Functions and configuration

15.1.1 Summary

The fields of semiconductor/LCD manufacturing systems, mounters, and others have strong demands for high accuracy, high speed, and efficiency. Therefore, the number of systems using a linear servo motor for a drive axis has been increasing. Since the linear servo system can obtain the characteristics of the high speed and the high acceleration/deceleration greater than the ball screw drive system. The linear servo system also does not have a ball screw wear which is a weak point in the ball screw drive system. This will extend the life of the equipment. In addition, since a response error due to backlash and friction does not occur, you can establish a high-accuracy system. The following shows the differences between the linear servo motor and the rotary servo motor.

15.2 Signals and wiring

WARNING

Any person who is involved in wiring should be fully competent to do the work. Before wiring, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier. Ground the servo amplifier and the linear servo motor securely. Do not attempt to wire the servo amplifier and the linear servo motor until they have been installed. Otherwise, it may cause an electric shock. The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric shock. To avoid an electric shock, insulate the connections of the power supply terminals.

CAUTION

Wire the equipment correctly and securely. Otherwise, the linear servo motor may operate unexpectedly, resulting in injury. Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may occur. Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur. The surge absorbing diode installed to the DC relay for control output should be fitted in the specified direction. Otherwise, the emergency stop and other protective circuits may not operate.

(2) Operation at the magnetic pole detection

WARNING Note that the magnetic pole detection automatically starts simultaneously with the turning-on of the servo-on command.

CAUTION If the magnetic pole detection is not executed properly, the linear servo motor may operate unexpectedly.

POINT

Establish the machine configuration to use LSP (Upper stroke end) and LSN (Lower stroke end). The machine may be damaged due to a collision without LSP and LSN. Assign LSP and LSN and perform the magnetic pole detection also in the torque control mode. At the magnetic pole detection, whether the linear servo motor moves in the positive or negative direction is unpredictable. Depending on the setting value of [Pr. PL09 Magnetic pole detection voltage level], an overload, overcurrent, magnetic pole detection alarm, or others may occur. After the magnetic pole detection, check the positioning accuracy with the test operation (positioning operation function) of MR Configurator2. When the absolute position linear encoder is used, if a gap is generated to the positional relation between the linear encoder and the linear servo motor, perform the magnetic pole detection again. The accuracy of the magnetic pole detection improves with no load. An alarm may occur when the linear encoder is not mounted properly, or when the linear encoder resolution setting ([Pr. PL02] and [Pr. PL03]) or the setting value of [Pr. PL09 Magnetic pole detection voltage level] is incorrect. For the machine that its friction becomes 30% or more of the continuous thrust, the linear servo motor may not operate properly after the magnetic pole detection. For the horizontal shaft of the machine that its unbalanced thrust becomes 20% or more of the continuous thrust, the linear servo motor may not operate properly after the magnetic pole detection. For the machine that multiple axes are connected like a tandem configuration, if you try to perform the magnetic pole detection simultaneously for multiple axes, the magnetic pole detection may not be executed. Perform the magnetic pole detection for each axis. At this time, set the axes that the magnetic pole detection is not performed for to servo-off.

POINT

For the incremental linear encoder, the magnetic pole detection is required every time the power is turned on.

By turning on SON (Servo-on) after power-on, the magnetic pole detection is automatically carried out. Therefore, there is no need to set the parameter (first digit of [Pr. PL01]) for executing the magnetic pole detection.

(Note) Magnetic pole detection completion position

Magnetic pole detection start position

Servo-on position

The linear servo motor moves to a magnetic pole detection start position upon servo-on, and the magnetic pole detection is executed.

The linear servo motor reciprocates several times and returns to the magnetic pole detection start position to complete the magnetic pole detection and to go into the servo-lock status. At this time, there may be a gap, approximately a quarter of the pitch against magnetic pole, from the start position.

Note. For the pitch against magnetic pole, refer to (2) (a) 2) Note 2 in this section.

(b) For the absolute position linear encoder

POINT

The magnetic pole detection is required at the following timing. When the system is set up (at the first startup of equipment) After a servo amplifier is replaced After a linear servo motor (primary-side or secondary-side) is replaced After a linear encoder (scale or head) is replaced or remounted

If a gap is generated to the positional relation between the linear encoder and the linear servo motor, perform the magnetic pole detection again.

Perform the magnetic pole detection in the following procedure.

1) Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" (Magnetic pole

detection at first servo-on). [Pr. PL01]

Magnetic pole detection at first servo-on (Initial value)

2) Execute the magnetic pole detection. (Refer to (2) (a) in this section.)

3) After the completion of the magnetic pole detection, change [Pr. PL01] to "_ _ _ 0" (Magnetic pole

detection disabled). [Pr. PL01]

Magnetic pole detection disabled

0

After the magnetic pole detection, by disabling the magnetic pole detection function with [Pr. PL01], the magnetic pole detection after each power-on is not required.

(3) Magnetic pole detection method setting

POINT In the following cases, set the magnetic pole detection method to the minute position detection method.

When a shorten travel distance at the magnetic pole detection is required When the magnetic pole detection by the position detection method is not completed

When a linear encoder with a resolution smaller than 0.05 m is used and the magnetic pole detection does not complete normally by minute position detection method, select "Enabled (1 _ _ _)" of "Minute position detection method - High-resolution encoder selection" in [Pr. PL08].

Set the magnetic pole detection method using the first digit of [Pr. PL08] (Magnetic pole detection method selection).

[Pr. PL08]

Magnetic pole detection method selection 0: Position detection method 4: Minute position detection method

(4) Setting of the magnetic pole detection voltage level by the position detection method For the magnetic pole detection by the position detection method, set the voltage level with [Pr. PL09 Magnetic pole detection voltage level]. For the magnetic pole detection by the minute position detection method, the voltage level setting is not required.

(a) Guideline of parameter settings

Set the parameters by referring to the following table.

15. USING A LINEAR SERVO MOTOR

(b) Setting procedure

1) Perform the magnetic pole detection, and increase the setting value of [Pr. PL09 Magnetic pole detection voltage level] until [AL. 50 Overload 1], [AL. 51 Overload 2], [AL. 33 Overvoltage], [AL. E1 Overload warning 1], and [AL. EC Overload warning 2] occur. Increase the setting value by five as a guide value. When these alarms and warnings occur during the magnetic pole detection by using MR Configurator2, the test operation of MR Configurator2 automatically completes and the servo-off status is established.

2) Specify the setting value that is an approximately 70% of the value set when [AL. 50 Overload 1],

[AL. 51 Overload 2], [AL. 33 Overvoltage], [AL. E1 Overload warning 1], and [AL. EC Overload warning 2] occurred as the final setting value. However, if [AL. 27 Initial magnetic pole detection error] occurs with this value, specify a value intermediate between the value set at [AL. 50 Overload 1], [AL. 51 Overload 2], [AL. 33 Overvoltage], [AL. E1 Overload warning 1], and [AL. EC Overload warning 2] and the value set at the magnetic pole detection alarm as the final setting value.

3) Perform the magnetic pole detection again with the final setting value to check there is no

problem.

(c) Setting example

15.3.3 Home position return

POINT Change the third digit value of [Pr. PL01] according to the linear encoder resolution. The incremental linear encoder and the absolute position linear encoder have different reference home positions at the home position return. For the incremental linear encoder, a home position (reference mark) of the linear encoder is necessary in the home position return direction. When you configure as follows, move the mover to LSN with JOG operation and perform home position to perform it in safe.

(1) Incremental linear encoder

CAUTION If the resolution or the stop interval (the third digit of [Pr. PL01]) of the linear encoder is large, it is very dangerous since the linear servo motor may crash into the stroke end.

(a) When the linear encoder home position (reference mark) exists in the home position return direction

When you use an incremental linear encoder, LZ (Encoder Z-phase pulse) from the servo amplifier will be the home position (reference mark) of the linear encoder. When two or more reference marks exist during the full stroke of the linear encoder, select "Enabled (1 _ _ _)" of "Linear scale multipoint Z-phase input function selection" in [Pr. PC28].

POINT To execute a home position return securely, start a home position return after moving the linear servo motor to the opposite stroke end with JOG operation and others. Change the third digit value of [Pr. PL01] according to the linear encoder resolution.

The home position return cannot be performed from the position which the home position of the linear encoder does not exist in the home position return direction. Move the mover to the stroke end on the opposite side of the home position return direction with the JOG operation from the controller and others, and then perform a home position return.

The position which turns on LZ (Encoder Z-phase pulse) differs depending on the directions of home position passing. When you need to set the home position return completion to the same position each time such as dog type home position return, always start home position return with the same direction.

(d) Caution for linear encoder which does not have the home position (reference mark)

The linear encoder which does not have the home position (reference mark), LZ (Encoder Z-phase pulse) of the servo amplifier does not be outputted. It is depending on positioning controllers to use whether LZ (Encoder Z-phase pulse) is necessary or not for home position return. Check the specifications of controllers.

(2) Absolute position linear encoder

POINT The data set type home position return can also be carried out.

The home position reference position using an absolute type linear encoder will be per 1048576 pulses based on the linear encoder home position (absolute position data = 0). You can change the stop interval at home position return with the third digit of [Pr. PL01].

The following shows the relation between the stop interval at the home position return and the linear encoder resolution. For example, when the linear encoder resolution is 0.001 m and the parameter for the stop interval at the home position return, [Pr. PL01], is set to "_ 5 _ _" (16777216 pulses), the stop interval is 16.777 mm. The value inside a bold box indicates the recommended stop interval for each linear encoder resolution.

15.3.4 Test operation mode in MR Configurator2

CAUTION The test operation mode is designed for checking servo operation. It is not for checking machine operation. Do not use this mode with the machine. Always use the linear servo motor alone. If the servo motor operates abnormally, use EM2 (Forced stop 2) to stop it.

POINT

The content described in this section indicates the environment where the servo amplifier and a personal computer are directly connected.

By using a personal computer and MR Configurator2, you can execute the positioning operation, the output signal (DO) forced output, and the program operation without connecting the controller. (1) Positioning operation

Positioning operation can be performed when there is no command from the controller. Use this operation with the forced stop reset. This operation may be used independently of whether servo-on, servo-off, or whether a controller is connected or not. Exercise control on the positioning operation screen of MR Configurator2.

15.3.5 Function

(1) Linear servo control error detection function

POINT For the linear servo control error detection function, the position and speed deviation error detections are enabled by default. ([Pr. PL04]: _ _ _ 3)

If the linear servo control gets unstable for some reasons, the linear servo motor may not operate properly. To detect this state and to stop operation, the linear servo control error detection function is used as a protective function. The linear servo control error detection function has three different detection methods: the position deviation, speed deviation, and thrust deviation. An error is detected when each method is enabled with [Pr. PL04 Linear servo motor/DD motor function selection 2]. The detection level can be changed with [Pr. PL05], [Pr. PL06], and [Pr. PL07].

When you compare the model feedback position ( 1)) and the feedback position ( 2)) in figure 15.1, if the deviation is more than the value of [Pr.

The initial value of this detection level is 50 mm. Change the set value as necessary.

(b) Speed deviation error detection

Set [Pr. PL04] to "_ _ _ 2" to enable the speed deviation error detection. [Pr. PL04]

When you compare the model feedback speed ( 3)) and the feedback speed ( 4)) in figure 15.1, if the deviation is more than the value of [Pr. PL06 Speed deviation error detection level] (1 mm/s to 5000 mm/s), [AL. 42.2 Servo control error by speed deviation] will occur and the linear servo motor will stop. The initial value of this detection level is 1000 mm/s. Change the set value as necessary.

(c) Thrust deviation error detection level

Set [Pr. PL04] to "_ _ _ 4" to enable the thrust deviation error detection. [Pr. PL04]

The initial value of this detection level is 100%. Change the set value as necessary.

(d) Detecting multiple deviation errors

When [Pr. PL04] is set as follows, multiple deviation errors can be detected. For the error detection methods, refer to (1) (a), (b), (c) in this section.

(2) Auto tuning function

POINT The auto tuning mode 1 may not be performed properly if the following conditions are not satisfied.

Time to reach 2000 mm/s is the acceleration/deceleration time constant of 5 s or less. The linear servo motor speed is 150 mm/s or higher. The load to mass of the linear servo motor primary-side ratio is 100 times or less. The acceleration/deceleration thrust is 10% or less of the continuous thrust.

The auto tuning function during the linear servo motor operation is the same as that of the rotary servo motor. However, the calculation method of the load to motor mass ratio (J ratio) differs. The load to motor mass ratio (J ratio) on the linear servo motor is calculated by dividing the load mass by the mass of the linear servo motor primary side.

Example) Mass of linear servo motor primary side

Load mass (excluding the mass of the linear servo motor primary side) Mass ratio

= 2 kg = 4 kg = 4/2 = 2 times

For the parameters set by the auto tuning function, refer to chapter 6.

(3) Machine analyzer function

POINT Make sure to perform the machine analyzer function after the magnetic pole detection. If the magnetic pole detection is not performed, the machine analyze function may not operate properly. The stop position at the completion of the machine analyzer function can be any position.

15.3.6 Absolute position detection system

When the linear servo motor is used with the absolute position detection system, an absolute position linear encoder is required. (1) Operating conditions of absolute position detection system

(a) Use an absolute type linear encoder.

(b) Perform the magnetic pole detection in the incremental system and disable the magnetic pole detection after the detection.

(c) Enable the absolute position detection system with [Pr. PA03 Absolute position detection system].

(2) Alarm detection

[AL. 25 Absolute position erased], [AL. 92 Battery cable disconnection warning], [AL. 9F Battery warning], and [AL. E3 Absolute position counter warning] are not provided for the linear servo motor.

(3) Backup

The linear encoder backs up the absolute position data. Therefore, the encoder battery need not be installed to the servo amplifier.

(4) Absolute position data transfer to controller

Refer to section 12.8 for absolute position data transfer to the controller.

15.4 Characteristics

15.4.1 Overload protection characteristics

An electronic thermal is built in the servo amplifier to protect the linear servo motor, servo amplifier and linear servo motor power wires from overloads. [AL. 50 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve shown in fig. 15.2. [AL. 51 Overload 2] occurs if the maximum current is applied continuously for several seconds due to machine collision, etc. Use the equipment on the left-side area of the continuous or broken line in the graph. Use the linear servo motor with 70% or less of the effective load ratio when it is in the servo lock state or in a small reciprocating motion. This servo amplifier has solid-state linear servo motor overload protection. (The servo motor overload current (full load current) is set on the basis of 120% rated current of the servo amplifier.)

15.4.2 Power supply capacity and generated loss

Table 15.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For thermal design of an enclosed type cabinet, use the values in the table in consideration for the worst operating conditions. The actual amount of generated heat will be intermediate between values at rated torque and servo-off according to the duty used during operation. When the linear servo motor is run at less than the rated speed, the power supply capacity will be smaller than the value in the table, but the servo amplifier's generated heat will not change. Mounting a heat sink outside of the cabinet enables to reduce heat in the cabinet and design a compact enclosed type cabinet.

15.4.3 Dynamic brake characteristics

CAUTION

The coasting distance is a theoretically calculated value that does not consider factors such as friction. The calculated distance is longer than the actual distance. If the braking distance is not longer than the calculated value, a moving part may crash into the stroke end, causing a dangerous situation. Install an anti-crash mechanism such as an air brake or an electric/mechanical stopper such as a shock absorber to reduce the shock of moving parts.

POINT

Do not use dynamic brake to stop in a normal operation as it is the function to stop in emergency. For a machine operating at the recommended load to motor mass ratio or less, the estimated number of usage times of the dynamic brake is 1000 times while the machine decelerates from the rated speed to a stop once in 10 minutes. Be sure to enable EM1 (Forced stop 1) after the linear servo motor stops when using EM1 (Forced stop 1) frequently in other than emergency.

The approximate coasting distance from when the dynamic brake is activated until when the linear servo motor stops can be calculated with the equation below. Lmax = V0 (0.03 + M (A + B V0

15.4.4 Permissible load to motor mass ratio when the dynamic brake is used

Use the dynamic brake under the load to motor mass ratio indicated in the following table. If the ratio is higher than this value, the dynamic brake may burn. If there is a possibility that the ratio may exceed the value, contact your local sales office. The values of the permissible load to motor mass ratio in the table are the values when the linear servo motor is used at the maximum speed.

When actual speed does not reach the maximum speed of the linear servo motor, calculate the permissible load to motor mass ratio at the time of using the dynamic brake by the following equation. (The upper limit is 300 times.) Permissible load to motor mass ratio of the dynamic brake = Value in the table (Servo motor maximum speed2/Actual using speed2) For example, when an actual using speed is 2 m/s or less for the LM-H3P2A-07P motor (maximum speed: 3.0 m/s), the equation will be as follows. Permissible load to motor mass ratio of dynamic brake = 40 32/22 = 90 [times]

CAUTION

When using the direct drive motor, read "Direct Drive Motor Instruction Manual".

POINT

Refer to section 1.4 for the software version of the servo amplifier that is compatible with the direct drive servo system. The MR-J4-03A6(-RJ) servo amplifier is not compatible with direct drive motor.

16.1 Functions and configuration

16.1.1 Summary

The fields of semiconductor/LCD manufacturing systems, mounters, and others have strong demands for high accuracy and efficiency. Therefore, the number of systems using a direct drive motor for a drive axis has been increasing. The direct drive servo system includes the following features. (1) Performance

(a) The direct drive servo system ensures the high-rigidity and the high-torque. A high-resolution encoder enables the high-accuracy control.

(b) The high-resolution encoder contributes to the high-accuracy indexing.

(c) Since reducer is no longer required, no backlash occurs. In addition, the settling time is reduced, and

the high-frequency operation is enabled.

(d) Since reducer is no longer required, the motor does not deteriorate with time by reducer. (2) Mechanism

(a) The motor's low profile design contributes to compact moving part of the machine and a low center of gravity for enhanced equipment stability.

(b) The motor has an inner rotor with hollow shaft which enables cables and pipes to be passed through.

(c) Lubrication and the maintenance due to abrasion are not required.

The following shows the differences between the direct drive motor and the rotary servo motor.

Note 1. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.

When not using the power factor improving DC reactor, short P3 and P4. 2. A 1-phase 200 V AC to 240 V AC power supply may be used with the servo amplifier of MR-J4-200A(-RJ) or less. For 1-phase

200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open. For the power supply specifications, refer to section 1.3.

3. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn off the magnetic contactor.

4. The battery unit is used for the absolute position detection system. (Refer to chapter 12.) 5. Always connect between P+ and D terminals. When using the regenerative option, refer to section 11.2. 6. The absolute position storage unit is used for the absolute position detection system. 7. This is for MR-J4-_A_, MR-J4-_A_-RJ has a CN2L connector. However, CN2L is not used for the direct drive servo system.

16.2 Signals and wiring

WARNING

Any person who is involved in wiring should be fully competent to do the work. Before wiring, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier. Ground the servo amplifier and the direct drive motor securely. Do not attempt to wire the servo amplifier and direct drive motor until they have been installed. Otherwise, it may cause an electric shock. The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric shock. To avoid an electric shock, insulate the connections of the power supply terminals.

CAUTION

Wire the equipment correctly and securely. Otherwise, the direct drive motor may operate unexpectedly, resulting in injury. Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may occur. Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur. The surge absorbing diode installed to the DC relay for control output should be fitted in the specified direction. Otherwise, the emergency stop and other protective circuits may not operate.

16. USING A DIRECT DRIVE MOTOR

16 - 6

Note 1. Use MR Configurator2. 2. For the absolute position detection system, always turn on the Z-phase pulse of the direct drive motor while the servo amplifier

power is on, and then turn the servo amplifier power supply off and on again. By turning off and on the power supply, the absolute position becomes confirmed. Without this operation, the absolute position will not be regained properly, and a warning will occur at the controller.

3 If the Z-phase pulse of the direct drive motor can be turned on manually, the Z-phase pulse does not have to be turned on by the magnetic pole detection or the JOG operation. For this operation, make sure to connect the direct drive motor encoder and the servo amplifier, and turn on the control circuit power supply of the servo amplifier (L11/L21) (turn off the main circuit power supply L1, L2, and L3). Ensure safety at this time.

4. Test operation cannot be performed in the absolute position detection system, either. To perform test operation, select "Disabled (incremental system) (_ _ _ 0)" in [Pr. PA03]. Refer to section 16.3.2 (1) for details.

5. After the servo amplifier is connected to the direct drive motor with an encoder cable, [AL. 25 Absolute position erased] will occur at the first power on. Cancel the alarm by turning on/off the power.

6. When the magnetic pole detection is performed with absolute position detection system by DIO transfer, [AL. 93 ABS data transfer warning] will occur. Refer to section 16.4 for details.

7. To cancel [AL. 93 ABS data transfer warning], cycle SON (Servo-on) or set a home position.

16.3.2 Magnetic pole detection

POINT The magnetic pole detection is not required for the configured absolute position detection system where the Z-phase pulse of the direct drive motor can be turned on manually. For this operation, always connect the direct drive motor encoder and the servo amplifier and turn on the control circuit power supply of the servo amplifier. Perform this operation by considering the safety. When performing a magnetic pole detection without using LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end), set [Pr. PL08 Linear servo motor/DD motor function selection 3] to "_ 1 _ _" to disable LSP and LSN. Set [Pr. PE47 Torque offset] to "0 (initial value)" before executing the magnetic pole detection. For the magnetic pole detection of vertical axis with direct drive motors, refer to section 2.1 of "Direct Drive Motor Instruction Manual".

Before the positioning operation of the direct drive motor, make sure to perform the magnetic pole detection. Before starting up the equipment, perform the test operation (positioning operation) of MR Configurator2.

(2) Operation at the magnetic pole detection

WARNING Note that the magnetic pole detection automatically starts simultaneously with the turning-on of the servo-on command.

CAUTION If the magnetic pole detection is not executed properly, the direct drive motor may operates unexpectedly.

POINT

Establish the machine configuration to use LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end). The machine may be damaged due to a collision without LSP and LSN. Assign LSP and LSN and perform the magnetic pole detection also in the torque control mode. At the magnetic pole detection, whether the motor rotates in the forward or reverse direction is unpredictable. Depending on the setting value of [Pr. PL09 Magnetic pole detection voltage level], an overload, overcurrent, magnetic pole detection alarm, or others may occur. After the magnetic pole detection, check the positioning accuracy with the test operation (positioning operation function) of MR Configurator2. The accuracy of the magnetic pole detection improves with no load.

(a) Incremental system

POINT

For the incremental system, the magnetic pole detection is required every time the power is turned on.

By turning on SON (Servo-on) after power-on, the magnetic pole detection is automatically carried out. Therefore, there is no need to set the parameter (first digit of [Pr. PL01]) for executing the magnetic pole detection.

POINT The magnetic pole detection is required in the following timings.

System set-up (at the first startup of equipment) When the Z-phase pulse of the direct drive motor is not turned on at the system setup (When the Z-phase pulse of the direct drive motor can be turned on manually, the magnetic pole detection is not required.) After a direct drive motor is replaced When [AL. 25 Absolute position erased] has occurred

Turn on the Z-phase pulse of the direct drive motor in JOG operation from the controller after the magnetic pole detection.

Perform the magnetic pole detection in the following procedure.

1) Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" (Magnetic pole

detection at first servo-on). [Pr. PL01]

Magnetic pole detection at first servo-on (initial value)

2) Execute the magnetic pole detection. (Refer to (2) (a) in this section.)

3) After the completion of the magnetic pole detection, change [Pr. PL01] to "_ _ _ 0" (Magnetic pole

detection disabled). [Pr. PL01]

Magnetic pole detection disabled

0

After the magnetic pole detection, by turning on the Z-phase pulse of the direct drive motor in JOG operation and by disabling the magnetic pole detection function with [Pr. PL01], the magnetic pole detection after each power-on is not required.

(3) Magnetic pole detection method setting

Set the magnetic pole detection method using the first digit of [Pr. PL08] (Magnetic pole detection method selection).

[Pr. PL08]

Magnetic pole detection method selection 0: Position detection method 4: Minute position detection method

(4) Setting of the magnetic pole detection voltage level by the position detection method For the magnetic pole detection by the position detection method, set the voltage level with [Pr. PL09 Magnetic pole detection voltage level]. For the magnetic pole detection by the minute position detection method, the voltage level setting is not required.

(a) Guideline of parameter settings

Set the parameters by referring to the following table.

[Pr. PL09] setting (guide value)

Servo status

Small Medium Large (10 or less (initial value) 50 or more)

Torques required for operation Small Large Overload, overcurrent alarm Seldom occurs Frequently occurs Magnetic pole detection alarm Frequently occurs Seldom occurs Magnetic pole detection accuracy Low High

(b) Setting procedure

1) Perform the magnetic pole detection, and increase the setting value of [Pr. PL09 Magnetic pole detection voltage level] until [AL. 50 Overload 1], [AL. 51 Overload 2], [AL. E1 Overload warning 1], and [AL. EC Overload warning 2] occur. Increase the setting value by five as a guide value. When these alarms and warnings occur during the magnetic pole detection by using MR Configurator2, the test operation of MR Configurator2 automatically completes and the servo-off status is established.

2) Specify the setting value that is an approximately 70% of the value set when [AL. 50 Overload 1],

[AL. 51 Overload 2], [AL. E1 Overload warning 1], and [AL. EC Overload warning 2] occurred as the final setting value. However, if [AL. 27 Initial magnetic pole detection error] occurs with this value, specify a value intermediate between the value set at [AL. 50 Overload 1], [AL. 51 Overload 2], [AL. E1 Overload warning 1], or [AL. EC Overload warning 2] and the value set at the magnetic pole detection alarm as the final setting value.

3) Perform the magnetic pole detection again with the final setting value.

In this example, the final setting value of [Pr. PL09] is 49 (Setting value at the alarm occurrence = 70 0.7).

16.3.3 Function

(1) Servo control error detection function

POINT For the servo control error detection function, the position and speed deviation error detections are enabled by default. ([Pr. PL04]: _ _ _ 3)

If the servo control gets unstable for some reasons, the direct drive motor may not operate properly. To detect this state and to stop operation, the servo control error detection function is used as a protective function. The servo control error detection function has three different detection methods: the position deviation, speed deviation, and torque deviation. An error is detected when each method is enabled with [Pr. PL04 Linear servo motor/DD motor function selection 2]. The detection level can be changed with [Pr. PL05], [Pr. PL06], and [Pr. PL07].

When you compare the model feedback position ( 1)) and the feedback position ( 2)) in figure 16.1, if the deviation is more than the value of [Pr. PL05 Position deviation error detection level] (1 (0.01 rev) to 1000 (10 rev)), [AL. 42.1 Servo control error by position deviation] will occur and the linear servo motor will stop. The initial value of this detection level is 0.09 rev. Change the set value as necessary.

When you compare the model feedback speed ( 3)) and the feedback speed ( 4)) in figure 16.1, if the deviation is more than the value of [Pr. PL06 Speed deviation error detection level] (1 r/min to 2000 r/min), [AL. 42.2 Servo control error by speed deviation] will occur and the linear servo motor will stop. The initial value of this detection level is 100 r/min. Change the set value as necessary.

(c) Torque deviation error detection level

Set [Pr. PL04] to "_ _ _ 4" to enable the torque deviation error detection. [Pr. PL04]

Torque deviation error detection enabled

When you compare the command torque ( 5)) and the feedback torque ( 6)) in figure 16.1, if the deviation is more than the value of [Pr. PL07 Torque/thrust deviation error detection level] (1% to 1000%), [AL. 42.3 Servo control error by torque/thrust deviation] will occur and the linear servo motor will stop. The initial value of this detection level is 100%. Change the set value as necessary.

(d) Detecting multiple deviation errors

When [Pr. PL04] is set as follows, multiple deviation errors can be detected. For the error detection methods, refer to (1) (a), (b), (c) in this section.

16.4 Absolute position detection system

POINT To configure the absolute position detection system by using the direct drive motor, the battery and the absolute position storage unit (MR-BTAS01) are required. For encoder cables and absolute position storage units, refer to "Direct Drive Motor Instruction Manual". Replacing the absolute position storage unit (MR-BTAS01) will erase the absolute position. Start up the direct drive motor again and perform home positioning. Replace the battery while the control circuit power is on. Replacing the unit during control circuit power supply off will cause [AL. 25 Absolute position erased]. A battery cannot be replaced using battery connection cable (MR- J3BTCBL03M). [AL. 25 Absolute position erased] will occur if the encoder cable is disconnected.

When you use the system with absolute position detection system by DIO transfer (set [Pr. PA03] to "_ _ _ 1") with the following conditions, the first servo-on after power on will trigger the magnetic pole detection and [AL. 93 ABS data transfer warning] will occur.

Magnetic pole detection always enabled (Set [Pr. PL03] to "_ _ _ 1".) The Z-phase pulse of the direct drive motor has not turned on.

When the magnetic pole detection is performed with absolute position detection system by DIO transfer, a deviation occurs between absolute position data of the servo amplifier side and controller side. If the operation is continued, positions will be mismatched. Therefore, [AL. 93 ABS data transfer warning] will occur on the servo amplifier side. To cancel [AL. 93 ABS data transfer warning], cycle SON (Servo-on) or set a home position.

16.5.1 Overload protection characteristics

An electronic thermal is built in the servo amplifier to protect the servo amplifier, direct drive motor, and direct drive motor power wires from overloads. [AL. 50 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve shown in fig. 16.2. [AL. 51 Overload 2] occurs if the maximum current is applied continuously for several seconds due to machine collision, etc. Use the equipment on the left-side area of the continuous or broken line in the graph. For the system where the unbalanced torque occurs, such as a vertical axis system, the unbalanced torque of the machine should be kept at 70% or less of the rated torque. This servo amplifier has solid-state direct drive motor overload protection for each axis. (The direct drive motor overload current (full load current) is set on the basis of 120% rated current of the servo amplifier.)

Note. If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a direct drive

motor stop status (servo-lock status) or in a 50 r/min or less low-speed operation status, the servo amplifier may malfunction regardless of the electronic thermal protection.

16.5.2 Power supply capacity and generated loss

Table 16.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For thermal design of an enclosed type cabinet, use the values in the table in consideration for the worst operating conditions. The actual amount of generated heat will be intermediate between values at rated torque and servo-off according to the duty used during operation. When the direct drive motor is run at less than the rated speed, the power supply capacity will be smaller than the value in the table, but the servo amplifier's generated heat will not change.

16.5.3 Dynamic brake characteristics

CAUTION

The coasting distance is a theoretically calculated value that does not consider factors such as friction. The calculated distance is longer than the actual distance. If the braking distance is not longer than the calculated value, a moving part may crash into the stroke end, causing a dangerous situation. Install an anti-crash mechanism such as an air brake or an electric/mechanical stopper such as a shock absorber to reduce the shock of moving parts.

POINT

Do not use dynamic brake to stop in a normal operation as it is the function to stop in emergency. For a machine operating at the recommended load to motor inertia ratio or less, the estimated number of usage times of the dynamic brake is 1000 times while the machine decelerates from the rated speed to a stop once in 10 minutes. Be sure to enable EM1 (Forced stop 1) after the direct drive motor stops when using EM1 (Forced stop 1) frequently in other than emergency.

(1) Dynamic brake operation

(a) Calculation of coasting distance Fig. 16.3 shows the pattern in which the servo motor comes to a stop when the dynamic brake is operated. Use equation 16.1 to calculate an approximate coasting distance to a stop. The dynamic brake time constant varies with the direct drive motor and machine operation speeds. (Refer to (1) (b) in this section.)

17. FULLY CLOSED LOOP SYSTEM

POINT The fully closed loop system is available for the servo amplifiers of which software version is A5 or above. When fully closed loop control system is used with this servo amplifier, "Linear Encoder Instruction Manual" is needed. Fully closed loop control system is available with position control mode. When fully closed loop control system is configured with MR-J4-_A_ servo amplifier, the following restrictions will be applied. However, these restrictions will not be applied for MR-J4-_A_-RJ servo amplifiers.

A/B/Z-phase differential output method encoder cannot be used. The load-side encoder and servo motor encoder is compatible with only the two-wire type. The four-wire type load-side encoder and servo motor encoder cannot be used. When you use the KG-KR and HG-MR series for driving and load-side encoder, the optional four-wire type encoder cables (MR-EKCBL30M-L, MR- EKCBL30M-H, MR-EKCBL40M-H, and MR-EKCBL50M-H) cannot be used. When an encoder cable of 30 m to 50 m is needed, fabricate a two-wire type encoder cable according to app. 8.

The MR-J4-03A6(-RJ) servo amplifier is not compatible with the fully closed loop system. The synchronous encoder Q171ENC-W8 can be used with servo amplifiers with software version A8 or later.

Note 1. Switching between semi closed loop control and fully closed loop control can be performed by changing the setting of [Pr. PE01]. When semi closed loop control is selected, a control is always performed on the bases of the position data of the servo motor encoder independently of whether the servo motor is at a stop or running.

2. When the fully closed loop system is enabled in [Pr. PE01], dual feedback control in which the servo motor feedback signal and load-side encoder feedback signal are combined by the dual feedback filter in [Pr. PE08] is performed. In this case, fully closed loop control is performed when the servo motor is at a stop, and semi closed loop control is performed when the servo motor is operating to improve control performance. When "4500" is set as the filter value of [Pr. PE08 Fully closed loop dual feedback filter], fully closed loop control is always performed.

The following table shows the functions of each control mode.

Control Description

Semi closed loop control

Feature Position is controlled according to the servo motor-side data.

Advantage Since this control is insusceptible to machine influence (such as machine resonance), the gains of the servo amplifier can be raised and the settling time shortened.

Disadvantage If the servo motor side is at a stop, the side may be vibrating or the load-side accuracy not obtained.

Dual feedback control

Feature Position is controlled according to the servo motor-side data and load-side data.

Advantage Control is performed according to the servo motor-side data during operation, and according to the load side-data at a stop in sequence to raise the gains during operation and shorten the settling time. A stop is made with the load-side accuracy.

Fully closed loop control

Feature Position is controlled according to the load-side data. Advantage The load-side accuracy is obtained not only at a stop but also during operation.

Disadvantage Since this control is susceptible to machine resonance or other influences, the gains of the servo amplifier may not rise.

(3) Selection of load-side encoder communication method

The communication method changes depending on the load-side encoder type. Refer to table 1.1 and "Linear Encoder Instruction Manual" for the communication method for each load- side encoder. Select the cable to be connected to CN2L connector in [Pr. PC44].

0 0 0 [Pr. PC44]

Load-side encoder cable communication method selection 0: Two-wire type 1: Four-wire type When using a load-side encoder of A/B/Z-phase differential output method, set "0". Incorrect setting will trigger [AL. 70] and [AL. 71]. Setting "1" while using a servo amplifier other than MR-J4-_A_-RJ will trigger [AL. 37].

(4) Setting of load-side encoder polarity

CAUTION Do not set an incorrect direction to "Encoder pulse count polarity selection" in [Pr. PC45]. An abnormal operation and a machine collision may occur if an incorrect direction is set, which cause a fault and parts damaged.

POINT

"Encoder pulse count polarity selection" in [Pr. PC45] is not related to [Pr. PA14 Rotation direction selection]. Make sure to set the parameter according to the relationships between servo motor and linear encoder/rotary encoder. Do not set an incorrect direction to "Encoder pulse count polarity selection" in [Pr. PC45]. Doing so may cause [AL. 42 Fully closed loop control error] during the positioning operation.

(5) Setting of feedback pulse electronic gear

POINT If an incorrect value is set in the feedback pulse electronic gear ([Pr. PE04], [Pr. PE05], [Pr. PE34], and [Pr. PE35]), [AL. 37 Parameter error] and an abnormal operation may occur. Also, it may cause [AL. 42.8 Fully closed loop control error by position deviation] during the positioning operation.

Set the electronic gear ([Pr. PE04], [Pr. PE34], [Pr. PE05], and [Pr. PE35]) for servo motor-side encoder pulses. Set the electronic gear so that the number of servo motor encoder pulses per servo motor revolution is converted into the number of load-side encoder pulses. The relation is as follows.

Number of load-side encoder pulses per servo motor revolution

= Number of servo motor encoder pulses per servo motor revolution [Pr. PE04] [Pr. PE34]

(6) Confirmation of load-side encoder position data

Check the load-side encoder mounting and parameter settings for any problems.

POINT Depending on the check items, MR Configurator2 may be used. Refer to section 17.3.8 for the data displayed on the MR Configurator2.

When checking the following items, the fully closed loop control mode must be set. For the setting of control mode, refer to (2) in this section.

No. Check item Confirmation method and description 1 Read of load-side encoder position

data With the load-side encoder in a normal state (mounting, connection, etc.), the load-side cumulative feedback pulses value is counted normally when the load-side encoder is moved. When it is not counted normally, the following factors can be considered. 1. An alarm occurred. 2. The installation of the load-side encoder was not correct. 3. The encoder cable was not wired correctly.

2 Read of load-side encoder home position (reference mark, Z-phase)

With the home position (reference mark, or Z-phase) of the load-side encoder in a normal condition (mounting, connection, etc.), the value of load-side encoder information 1 is cleared to 0 when the home position (reference mark, or Z-phase) is passed through by moving the load-side encoder. When it is not cleared, the following factors can be considered. 1. The installation of the load-side encoder was not correct. 2. The encoder cable was not wired correctly.

3 Confirmation of load-side encoder feedback direction (Setting of load-side encoder polarity)

Confirm that the directions of the cumulative feedback pulses of servo motor encoder (after gear) and the load-side cumulative feedback pulses are matched by moving the device (load-side encoder) manually in the servo-off status. If mismatched, reverse the polarity.

4 Setting of load-side encoder electronic gear

When the servo motor and load-side encoder operate synchronously, the servo motor-side cumulative feedback pulses (after gear) and load-side cumulative feedback pulses are matched and increased. If mismatched, review the setting of fully closed loop control feedback electronic gear ([Pr. PE04], [Pr. PE05], [Pr. PE34], and [Pr. PE35]) with the following method. 1) Check the servo motor-side cumulative feedback pulses (before gear). 2) Check the load-side cumulative feedback pulses. 3) Check that the ratio of above 1) and 2) has been that of the feedback electronic gear.

17.3.2 Home position return

(1) General instruction Home position return is all performed according to the load-side encoder feedback data, independently of the load-side encoder type. It is irrelevant to the Z-phase position of the servo motor encoder. In the case of a home position return using a dog signal, the home position (reference mark) must be passed through when an incremental type linear encoder is used, or the Z-phase be passed through when a rotary encoder is used, during a period from a home position return start until the dog signal turns off. For the linear encoder, a home position (reference mark) of the linear encoder is necessary in the home position return direction.

POINT

When you configure as follows, move the mover to LSN with JOG operation and perform home position to perform it in safe.

Non-returnable area: Home position return cannot be performed when started from this area.

(2) Load-side encoder types and home position return methods

(a) About proximity dog type home position return using absolute type linear encoder When an absolute type linear encoder is used, the home position standard position is the position per servo motor revolution to the linear encoder home position (absolute position data = 0). In the case of a proximity dog type home position return, the nearest position after proximity dog off is the home position. The linear encoder home position may be set in any position.

(b) Home position return using incremental linear encoder

When you use an incremental linear encoder, LZ (Encoder Z-phase pulse) from the servo amplifier will be the home position (reference mark) of the linear encoder. Two or more home positions (reference marks) should not be set. In addition, the home position return cannot be executed without home position (reference mark).

1) Caution for passing the home position (reference mark) An interval for turning on home position (reference mark) signal of the linear encoder has a certain width. (Specifications differ depending on the linear encoders. For details, refer to "Linear Encoder Instruction Manual".)

Example: When Z-phase is recognized at startup

B A

Home position signal

A is recognized as the on position. B is recognized as

the on position.

The position which turns on a signal differs depending on the directions of home position passing. When you need to set the home position return completion to the same position each time such as dog type home position return, always start home position return with the same direction.

2) Caution for linear encoder which does not have the home position (Z-phase)

The linear encoder which does not have the home position (Z-phase), LZ (Encoder Z-phase pulse) of the servo amplifier does not be outputted. The home position return can be performed depending on specifications of controllers even if LZ (Encoder Z-phase pulse) is not outputted. Check the controller specifications of the home position return.

17.3.3 Fully closed loop control error detection functions

If fully closed loop control becomes unstable for some reason, the speed at servo motor side may increase abnormally. The fully closed loop control error detection function is a protective function designed to pre- detect it and stop operation. The fully closed loop control error detection function has two types of detection methods: speed deviation and position deviation. Select a detection method with [Pr. PE03 Fully closed loop function selection 2]. The detection level setting can be changed using [Pr. PE06] and [Pr. PE07]. (1) Parameter

17.3.7 Absolute position detection system under fully closed loop system

An absolute type linear encoder is necessary to configure an absolute position detection system under fully closed loop control using a linear encoder. In this case, the encoder battery (MR-BAT6V1SET) need not be installed to the servo amplifier. When an rotary encoder is used, an absolute position detection system can be configured by installing the encoder battery (MR-BAT6V1SET) to the servo amplifier. In this case, the battery life will be shorter because the power consumption is increased as the power is supplied to the two encoders of motor side and load side. If using an absolute position detection system with a linear encoder, enable the system with [Pr. PA03 Absolute position detection system], and use this servo with the following restrictions. (1) Using conditions

(a) Use an absolute type linear encoder with the load-side encoder.

(b) Set [Pr. PA01] to "_ _ 1 _", and [Pr. PE01] to "_ _ _ 0". (2) Absolute position detection range using encoder

Encoder type Absolute position detection enabled range Linear encoder (serial interface)

Movable distance range of linear encoder (within 32-bit absolute position data)

(3) Alarm detection

The absolute position-related alarm ([AL. 25]) and warnings (AL. 92] and [AL. 9F]) are not detected. (4) Absolute position data transfer to controller

It is the same process as rotary servo motors. (Refer to section 12.8.)

Connect a circuit protector between the power supply and power supply voltage input terminals (24/PM) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the side of the servo amplifier's power supply. If a circuit protector is not connected, continuous flow of a large current may cause a fire when the servo amplifier malfunctions. Use ALM (Malfunction) to switch main circuit power supply off. Not doing so may cause a fire when a regenerative transistor malfunctions or the like may overheat the built-in regenerative resistor. Check the servo amplifier model, and then input proper voltage to the servo amplifier power supply. If input voltage exceeds the upper limit of the specification, the servo amplifier will break down. Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.

POINT

EM2 has the same function as EM1 in the torque control mode.

18.3.3 Selection of main circuit power supply/control circuit power supply

The inrush current at power on will be large because a resistance for protecting inrush current is not built-in in the main circuit power supply of the servo amplifier. The main circuit capacitor capacity of the servo amplifier is approximately 270 F. When the load characteristic (overcurrent protection criteria) of the power unit is current fold back method, the power cannot be started. Be careful when selecting a power. Especially when the power is turned ON/OFF on the power unit output side, approximately 100 s to 300 s instantaneous current will flowed at power on due to capacitor charge. Therefore, a power unit such as one which operates overcurrent at 1 ms or less cannot be used. A circuit to protect inrush current at power on is built-in in the control circuit power supply of servo amplifier. In addition, when using main circuit power supply and control circuit power supply, use a reinforced insulating type. 18.3.4 Power-on sequence

POINT The voltage of analog monitor output, output signal, etc. may be unstable at power-on.

(1) Power-on procedure

1) When wiring the power supply, use a circuit protector for the power supply (24/PM). Configure up an external sequence so that the relay connected to PM turns off when an alarm occurs.

2) Switch on the control circuit power supply (24/0) simultaneously with the main circuit power

supply (PM/0) or before switching on the main circuit power supply. If the main circuit power supply is not on, the display shows the corresponding warning. However, by switching on the main circuit power supply, the warning disappears and the servo amplifier will operate properly.

3) The servo amplifier receives the SON (Servo-on) within 2.5 s to 3.5 s after the main circuit power

supply is switched on. Therefore, when SON (Servo-on) is switched on simultaneously with the main circuit power supply, the base circuit will switch on in about 2.5 s to 3.5 s, and the RD (Ready) will switch on in further about 5 ms, making the servo amplifier ready to operate. (Refer to (2) in this section.)

4) When RES (Reset) is switched on, the base circuit is shut off and the servo motor shaft coasts.

Note 1. To prevent an electric shock, always connect the CNP1 noiseless grounding terminal ( marked) of the servo amplifier to the

grounding terminal (PE) of the cabinet. 2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will malfunction and will not output

signals, disabling EM2 (Forced stop 2) and other protective circuits. 3. The forced stop switch (normally closed contact) must be installed. 4. Supply 24 V DC 10% to interfaces from outside. The total current capacity is up to 300 mA. 300 mA is the value applicable

when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.9.2 (1) that gives the current value necessary for the interface. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they can be configured by one. For 24 V DC power for I/O signal, use power other than 24 V DC power of servo amplifier control circuit power supply.

5. When starting operation, always turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end). (Normally closed contact)

6. ALM (Malfunction) turns on in normal alarm-free condition. When this signal (normally closed contact) is switched off (at occurrence of an alarm), the output of the programmable controller should be stopped by the sequence program.

7. The pins with the same signal name are connected in the servo amplifier. 8. This length applies to the command pulse train input in the differential line driver type. It is 2 m or less in the open-collector

type. 9. Use SW1DNC-MRC2-_. (Refer to section 11.7.) 10. The USB communication function and RS-422 communication function are mutually exclusive. They cannot be used together. 11. This connection is not necessary for RD75D, LD75D and QD75D. However, to enhance noise tolerance, it is recommended to

connect LG of servo amplifier and control common depending on the positioning module. 12. When a command cable for connection with the controller side malfunctions due to disconnection or noise, a position

mismatch can occur. To avoid the position mismatch, check Encoder A-phase pulse and Encoder B-phase pulse on the controller side.

13. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo amplifier.

14. Plus and minus of the power of source interface are the opposite of those of sink interface. 15. CLER and CLEARCOM of source interface are interchanged to sink interface.

18.3.10 Grounding

WARNING Ground the servo amplifier and servo motor securely. To prevent an electric shock, always connect the noiseless grounding terminal (marked ) of the servo amplifier to the grounding terminal of the cabinet.

The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending on the wiring and ground cable routing, the servo amplifier may be affected by the switching noise (due to di/dt and dv/dt) of the transistor. To prevent such a fault, refer to the following diagram and always ground. To conform to the EMC Directive, refer to "EMC Installation Guidelines".

03. Recheck of main circuit power supply voltage and wiring

05. Turning on of main circuit power supply

Check that the servo amplifiers and servo motors are wired correctly. (Refer to section 18.4.3.) Set the main circuit power supply selection (48 V DC or 24 V DC) to servo amplifier. Set [Pr. PC27] according to the flow of 02-1 to 02-4. Set this setting only when using 24 V DC. (The initial value of the main circuit power supply selection is 48 V DC. When using 48 V DC, turn the control circuit power supply on and move on to procedure 03.) To set the parameter to servo amplifier, turn on the control circuit power supply. At this time, do not turn on the main circuit power supply. Set [Pr. PC027] setting to "_ 1 _ _". To reflect the parameter setting, turn off the control circuit power supply. Turn on the control circuit power supply on again, and check that [Pr. PC27] is changed to "24 V DC (_ 1 _ _)". At this time, do not turn on the main circuit power supply. Make sure that the main circuit power supply voltage of the servo amplifier to be turned on matches with the voltage set by [Pr. PC27] and that the servo amplifiers and servo motors are wired correctly by visual inspection, DO forced output function (section 18.5.9), etc. Check the surrounding environment of the servo amplifier and servo motor. (Refer to section 18.4.4.) Turn on the main circuit power. Set the parameters as necessary, such as the used operation mode. (Refer to sections 18.6, 4.2.4, 4.3.4, and 4.4.4.) For the test operation, with the servo motor disconnected from the machine and operated at the speed as low as possible, check whether the servo motor rotates correctly. (Refer to sections 4.2.3, 4.3.3, and 4.4.3.) For the test operation with the servo motor disconnected from the machine and operated at the speed as low as possible, give commands to the servo amplifier and check whether the servo motor rotates correctly. After connecting the servo motor with the machine, check machine motions with sending operation commands from the servo system controller. Make gain adjustment to optimize the machine motions. (Refer to chapter 6.) Stop giving commands and stop operation. Other conditions that stop the servo motor are mentioned in sections 4.2.2, 4.3.2, and 4.4.2.

Item Detailed explanation Cable bending life Section 10.4

18.7.1 Overload protection characteristics

An electronic thermal is built in the servo amplifier to protect the servo motor, servo amplifier and servo motor power wires from overloads. [AL. 50 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve shown in fig. 18.1. [AL. 51 Overload 2] occurs if the maximum current is applied continuously for several seconds due to machine collision, etc. Use the equipment on the left-side area of the continuous or broken line in the graph. For the system where the unbalanced torque occurs, such as a vertical axis system, the unbalanced torque of the machine should be kept at 70% or less of the rated torque. This servo amplifier has servo motor overload protective function. (The servo motor overload current (full load current) is set on the basis of 120% rated current of the servo amplifier.)

18.7.2 Power supply capacity and generated loss

Table 18.4 indicates the required power supply capacities for main circuit and losses generated under rated load of the servo amplifier. For thermal design of an enclosed type cabinet, use the values in the table in consideration for the worst operating conditions. The actual amount of generated heat will be intermediate between values at rated torque and servo-off according to the duty used during operation. When the servo motor is operated under the rated speed, required power supply capacities for main circuit will be less than the value of the table.

18.7.3 Dynamic brake characteristics

POINT The dynamic brake of MR-J4-03A6(-RJ) is an electronic type. Do not use dynamic brake to stop in a normal operation as it is the function to stop in emergency. Be sure to enable EM1 (Forced stop 1) after servo motor stops when using EM1 (Forced stop 1) frequently in other than emergency. The time constant "" for the electronic dynamic brake will be shorter than that of normal dynamic brake. Therefore, coasting distance will be longer than that of normal dynamic brake. For how to set the electronic dynamic brake, refer to [Pr. PF09] and [Pr. PF15].

(1) Dynamic brake operation

(a) Calculation of coasting distance Fig. 18.2 shows the pattern in which the servo motor comes to a stop when the dynamic brake is operated. Use equation 18.1 to calculate an approximate coasting distance to a stop. The dynamic brake time constant varies with the servo motor and machine operation speeds. (Refer to (1) (b) in this section.) A working part generally has a friction force. Therefore, actual coasting distance will be shorter than a maximum coasting distance calculated with the following equation.

(2) Permissible load to motor inertia when the dynamic brake is used

Use the dynamic brake under the load to motor inertia ratio indicated in the following table. If the ratio is higher than this value, the servo amplifier may burn. If there is a possibility that the ratio may exceed the value, contact your local sales office. The values of the permissible load to motor inertia ratio in the table are the values at the maximum rotation speed of the servo motor.

18.7.4 Inrush currents at power-on of main circuit and control circuit

POINT The inrush current values can change depending on frequency of turning on/off the power and ambient temperature.

Since large inrush currents flow in the power supplies, use circuit protector. For circuit protectors, it is recommended that the inertia delay type, which is not tripped by an inrush current, be used. Refer to section 18.8.4 for details of the circuit protector. This following table indicates the inrush current (reference data) when the power of output side of power unit is turned on in the conditions: main circuit of 55.2 V DC, control circuit of 26.4 V DC, and wiring length of 1 m.

19.2.2 Installation and removal of the MR-D01 extension I/O unit

WARNING

Before installing or removing MR-D01, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from the front of the servo amplifier.

CAUTION

Avoid installing and removing MR-D01 repeatedly. Any contact failure of the connector may be caused. Avoid unsealing MR-D01 to be free of dust and dirt against the connector except installing. Make sure to use the pre-packing when storing. Avoid using MR-D01 of which the hook and knobs for fixing are damaged. Any contact failure of the connector may be caused. When mounting/dismounting MR-D01 to/from MR-J4-500A-RJ to MR-J4-22KA-RJ and MR-J4-350A4-RJ to MR-J4-22KA4-RJ servo amplifiers, avoid dropping out the installing screw inside it. Otherwise, it may cause a malfunction. When mounting MR-D01 to MR-J4-500A-RJ to MR-J4-22KA-RJ and MR-J4- 350A4-RJ to MR-J4-22KA4-RJ servo amplifiers, avoid damaging the control board by the fixing plate. Otherwise, it may cause a malfunction. Make sure to tighten MR-D01 with the enclosed installing screws when installing.

(b) Installation of two or more servo amplifiers

POINT

Close mounting is possible depending on the capacity of the servo amplifier. For the possibility of close mounting, refer to section 1.3. When mounting the servo amplifiers closely, do not install the servo amplifier whose depth is larger than that of the left side servo amplifier since CNP1, CNP2, and CNP3 connectors cannot be disconnected.

Leave a large clearance between the top of the servo amplifier and the cabinet walls, and install a cooling fan to prevent the internal temperature of the cabinet from exceeding the environmental conditions. When mounting the servo amplifiers closely, leave a clearance of 1 mm between the adjacent servo amplifiers in consideration of mounting tolerances. In this case, operate the servo amplifiers at the ambient temperature of 0 C to 45 C or at 75% or less of the effective load ratio.

Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo amplifier to the

protective earth (PE) of the cabinet. 2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will malfunction and will not output

signals, disabling EM2 (Forced stop 2) and other protective circuits. 3. The forced stop switch (normally closed contact) must be installed. 4. Supply 24 V DC 10% to interfaces from outside. The total current capacity of these power supplies must be 500 mA or lower.

500 mA is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.9.2 (1) that gives the current value necessary for the interface. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they can be configured by one.

5. When starting operation, always turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end). (Normally closed contact)

6. ALM (Malfunction) turns on in normal alarm-free condition. (Normally closed contact) When this signal is switched off (at occurrence of an alarm), the output of the programmable controller should be stopped by the sequence program.

7. The pins with the same signal name are connected in the servo amplifier. 8. This length applies to the command pulse train input in the differential line driver type. It is 2 m or less in the open-collector

type. 9. Use SW1DNC-MRC2-_. (Refer to section 11.7.) 10. Controllers or parameter units can also be connected via the CN3 connector with the RS-422/RS-485 communication. Note

that using the USB communication function (CN5 connector) prevents the RS-422/RS-485 communication function (CN3 connector) from being used, and vice versa. They cannot be used together.

11. This connection is not necessary for RD75D, LD75D, and QD75D. However, to enhance noise tolerance, it is recommended to connect LG of servo amplifier and control common depending on the positioning module.

12. When not using the STO function, attach the short-circuit connector came with a servo amplifier. 13. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo

amplifier. 14. Plus and minus of the power of source interface are the opposite of those of sink interface. 15. CLEAR and CLEARCOM of source interface are interchanged to sink interface. 16. Disconnection of the command cable connected to the controller, or noise may cause a position mismatch. To avoid the

position mismatch, check encoder A-phase pulse and encoder B-phase pulse on the controller side. 17. The devices can be changed by [Pr. PD03] to [Pr. PD14], [Pr. PD17] to [Pr. PD22], and [Pr. PD43] to [Pr. PD46]. 18. Supply 24 V DC 10% to interfaces of the MR-D01 from outside. The total current capacity of these power supplies must be

800 mA or lower. 800 mA is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. For the amperage required for interfaces, refer to section 3.9.2 (1).

19. As the 24 V DC for the input/output signals, one 24 V DC power supply can be used to supply to the servo amplifier and MR- D01. In this case, select an appropriate power supply capacity depending on the number of points of the input/output signals to be used.

20. The CN1-27 pin and CN20-12 pin are exclusive. The CN1-27 pin is set by default. Select this item with [Pr. Po11]. 21. OTLA will be available when TL (External torque limit selection) is enabled with [Pr. Po02] to [Pr. Po07], [Pr. Po27], and [Pr.

Po28]. (Refer to section 19.5.3 (5).) 22. The devices can be changed by [Pr. Po02] to [Pr. Po07]. 23. The device can be changed by [Pr. Po08] and [Pr. Po09]. 24. Output devices are not assigned by default. Assign the output devices with [Pr. PD47], [Pr. Po08], and [Pr. Po09] as

necessary. 25. Input devices are not assigned by default. Assign the input devices with [Pr. Po05], [Pr. Po06], [Pr. Po27], and [Pr. Po28] as

necessary.

Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo amplifier to the

protective earth (PE) of the cabinet. 2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will malfunction and will not output

signals, disabling EM2 (Forced stop 2) and other protective circuits. 3. The forced stop switch (normally closed contact) must be installed. 4. Supply 24 V DC 10% to interfaces from outside. The total current capacity of these power supplies must be 500 mA or lower.

500 mA is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.9.2 (1) that gives the current value necessary for the interface. A 24 V DC power supply can be used for both input signal and output signal.

5. When starting operation, always turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end). (Normally closed contact)

6. ALM (Malfunction) turns on in normal alarm-free condition. (Normally closed contact) 7. The pins with the same signal name are connected in the servo amplifier. 8. TLA will be available when TL (External torque limit selection) is enabled with [Pr. PD03] to [Pr. PD22]. (Refer to section 3.6.1

(5).) 9. Use SW1DNC-MRC2-_. (Refer to section 11.7.) 10. Controllers or parameter units can also be connected via the CN3 connector with the RS-422/RS-485 communication. Note

that using the USB communication function (CN5 connector) prevents the RS-422/RS-485 communication function (CN3 connector) from being used, and vice versa. They cannot be used together.

11. When not using the STO function, attach the short-circuit connector came with a servo amplifier. 12. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo

amplifier. 13. Plus and minus of the power of source interface are the opposite of those of sink interface. 14. The devices can be changed by [Pr. PD03] to [Pr. PD14], [Pr. PD17] to [Pr. PD22], and [Pr. PD43] to [Pr. PD46]. 15. Supply 24 V DC 10% to interfaces of the MR-D01 from outside. The total current capacity of these power supplies must be

800 mA or lower. 800 mA is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. For the amperage required for interfaces, refer to section 3.9.2 (1).

16. As the 24 V DC for the input/output signals, one 24 V DC power supply can be used to supply to the servo amplifier and MR- D01. In this case, select an appropriate power supply capacity depending on the number of points of the input/output signals to be used.

17. The CN1-2 pin and CN20-2 pin are exclusive. The CN1-2 pin is set by default. Select this item with [Pr. Po11]. 18. The CN1-27 pin and CN20-12 pin are exclusive. The CN1-27 pin is set by default. Select this item with [Pr. Po11]. 19. OTLA will be available when TL (External torque limit selection) is enabled with [Pr. Po02] to [Pr. Po07], [Pr. Po27], and [Pr.

Po28]. (Refer to section 11.5.3 (6).) 20. The devices can be changed by [Pr. Po02] to [Pr. Po07]. 21. The device can be changed by [Pr. Po08] and [Pr. Po09]. 22. Output devices are not assigned by default. Assign the output devices with [Pr. PD47], [Pr. Po08], and [Pr. Po09] as

necessary. 23. Input devices are not assigned by default. Assign the input devices with [Pr. Po05], [Pr. Po06], [Pr. Po27], and [Pr. Po28] as

necessary.

(5) Torque limit

CAUTION

If the torque limit is canceled during servo-lock, the servo motor may suddenly rotate according to position deviation in respect to the command position. When using the torque limit, check that [Pr. PB06 Load to motor inertia ratio] is set properly. Improper settings may cause an unexpected operation such as an overshoot.

POINT

To use OTLA (Analog torque limit), set [Pr. Po11] to "_ 1 _ _".

(a) Torque limit and torque

By setting [Pr. PA11 Forward rotation torque limit] or [Pr. PA12 Reverse rotation torque limit], torque is always limited to the maximum value during operation. A relation between the limit value and servo motor torque is as follows.

A relation between the applied voltage of OTLA (Analog torque limit) and the torque limit value of the servo motor is as follows. Torque limit values will vary about 5% relative to the voltage depending on products. At the voltage of less than 0.05 V, torque may vary as it may not be limited sufficiently. Therefore, use this function at the voltage of 0.05 V or more.

App. 5.2 Terms related to safety

App. 5.2.1 Stop function for IEC/EN 61800-5-2

(1) STO function (Refer to IEC/EN 61800-5-2: 2007 4.2.2.2 STO.) This function is integrated into the MR-J4 series servo amplifiers. The STO function shuts down energy to servo motors, thus removing torque. This function electronically cuts off power supply in servo amplifiers for MR-J4 series servo amplifiers. The purpose of this function is as follows.

1) Uncontrolled stop according to stop category 0 of IEC/EN 60204-1

2) Preventing unexpected start-up

(2) SS1 function (Refer to IEC/EN 61800-5-2: 2007 4.2.2.3C Safe stop 1 temporal delay.)

SS1 is a function which initiates the STO function when the previously set delay time has passed after the servo motor starts decelerating. The delay time can be set with MR-J3-D05. The purpose of this function is as follows. This function is available by using an MR-J4 series servo amplifier with MR-J3-D05.

Controlled stop according to stop category 1 of IEC/EN 60204-1

App. 5.2.2 Emergency operation for IEC/EN 60204-1

(1) Emergency stop (Refer to IEC/EN 60204-1: 2005 9.2.5.4.2 Emergency Stop.) Emergency stop must override all other functions and actuation in all operation modes. Power to the machine driving part which may cause a hazardous state must be either removed immediately (stop category 0) or must be controlled to stop such hazardous state as soon as possible (stop category 1). Restart must not be allowed even after the cause of the emergency state has been removed.

(2) Emergency switching off (Refer to IEC/EN 60204-1: 2005 9.2.5.4.3 Emergency Switching OFF.)

Removal of input power to driving device to remove electrical risk and to meet above mentioned safety standards.

APPENDIX

App. 5.3 Cautions

The following basic safety notes must be read carefully and fully in order to prevent injury to persons or damage to property. Only qualified personnel are authorized to install, start-up, repair or service the machines in which these components are installed. They must be familiar with all applicable local regulations and laws in which machines with these components are installed, particularly the standards and guidelines mentioned in this Instruction Manual and the requirements mentioned in ISO/EN ISO 13849-1:2015, IEC 61508, IEC/EN 61800-5-2, and IEC/EN 60204-1. The staff responsible for this work must be given express permission from the company to perform start-up, programming, configuration, and maintenance of the machine in accordance with the safety standards.

WARNING Improper installation of the safety related components or systems may cause improper operation in which safety is not assured, and may result in severe injuries or even death.

Protective Measures

As described in IEC/EN 61800-5-2, the Safe Torque Off (STO) function only prevents the servo amplifier from supplying energy to the servo motor. Therefore, if an external force acts upon the drive axis, additional safety measures, such as brakes or counter-weights must be used.

App. 5.4 Residual risk

Machine manufacturers are responsible for all risk evaluations and all associated residual risks. Below are residual risks associated with the STO/EMG function. Mitsubishi Electric is not liable for any damages or injuries caused by the residual risks. (1) The SS1 function only guarantees the delay time before STO/EMG is engaged. Proper setting of this

delay time is the full responsibility of the company and/or individuals responsible for installation and commissioning of the safety related system. The system, as a whole, must pass safety standards certification.

(2) When the SS1 delay time is shorter than the required servo motor deceleration time, if the forced stop

function is malfunctioning, or if STO/EMG is engaged while the servo motor is still rotating; the servo motor will stop with the dynamic brake or freewheeling.

(3) For proper installation, wiring, and adjustment, thoroughly read the installation guide of each individual

safety related component. (4) Be sure that all safety related switches, relays, sensors, etc., meet the required safety standards.

A Certification Body has confirmed that the Mitsubishi Electric safety-related components mentioned in this manual meet ISO/EN ISO 13849-1:2015 Category 3, PL d and IEC 61508 SIL 2.

(5) Safety is not assured until safety-related components of the system are completely installed or adjusted. (6) When replacing a servo amplifier etc. or MR-J3-D05, confirm that the new equipment is exactly the same

as those being replaced. Once installed, be sure to verify the performance of the functions before commissioning the system.

APPENDIX

App. - 23

(7) Perform all risk assessments and safety level certification to the machine or the system as a whole.

It is recommended that a Certification Body final safety certification of the system be used. (8) To prevent accumulation of multiple malfunctions, perform a malfunction check at regular intervals as

deemed necessary by the applicable safety standard. Regardless of the system safety level, malfunction checks should be performed at least once per year.

(9) If the upper and lower power module in the servo amplifier are shorted and damaged simultaneously, the

servo motor may make a half revolution at a maximum. App. 5.5 Block diagram and timing chart

App. 7.4 Values of the maximum current command (maximum torque) when the analog monitor is at the maximum/minimum voltage

Values of the maximum current command (maximum torque) when the analog monitor is at the maximum/minimum voltage are listed. The current command (torque) outputs the maximum current command (maximum torque) at 8 V (5 V 3 V for MR-J4-03A6). The maximum current command (maximum torque) may not match the rated current/maximum current ratio since it is created from the torque current in the servo amplifier. App. 7.4.1 Rotary servo motor

App. 10.3.3 Specifications

(a) Special coating Using the MR-J4 series in an atmosphere containing a corrosive gas may cause its corrosion with time, resulting in a malfunction. For the printed circuit board of the servo amplifiers with a special coating specification, a urethane coating agent is applied to some parts capable of being coated technically (except LEDs, connectors, terminal blocks, etc.) to improve the resistance to corrosive gases. Use a servo amplifier with a special coating specification specifically for applications susceptible to corrosive gases, including tire manufacturing and water treatment. Although the special coating-specification products have the improved resistance to corrosive gases, proper operations in environments mentioned above are not guaranteed. Therefore, perform periodic inspections for any abnormality.

(b) Standard for corrosive gases

In IEC 60721-3-3, corrosive gases refer to sea salt, sulfur dioxide, hydrogen sulfide, chlorine, hydrogen chloride, hydrogen fluoride, ammonia, ozone, and nitrogen oxides shown in the environmental parameter column of the table below. The table also shows the corrosive gas concentrations defined in IEC 60721-3-3, Class 3C2.

App. 14 Status of general-purpose AC servo products for compliance with the China RoHS

directive

(1) Summary The China RoHS directive: (Management Methods for Controlling Pollution by Electronic Information Products) came into effect on March 1, 2007. The China RoHS directive was replaced by the following China RoHS directive: (Management Methods for the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products). The succeeding China RoHS directive has been in effect since July 1, 2016. The China RoHS directive restricts the use of six hazardous substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE)) and other hazardous substances specified by the State (currently no applicable substances). The EU RoHS directive (2011/65/EU) also restricts the use of the above six hazardous substances.

(2) Status of our products for compliance with the China RoHS directive

The following tables show the content of six hazardous substances in our products and Environment- Friendly Use Period marks. Table app. 4 is created based on the standard SJ/T11364.

(3) Difference between the China RoHS directive and the EU RoHS directive

The China RoHS directive allows no restriction exemption unlike the EU RoHS directive. Although a product complies with the EU RoHS directive, a hazardous substance in the product may be considered to be above the limit requirement (marked " ") in the China RoHS directive. The following shows some restriction exemptions and their examples according to the EU RoHS directive.

Lead as an alloying element in steel for machining purposes and in galvanized steel containing up to 0.35% lead by weight, lead as an alloying element in aluminum containing up to 0.4% lead by weight, and copper alloy containing up to 4% lead by weight, e.g. brass-made insert nuts Lead in high melting temperature type solders (i.e. lead-based alloys containing 85% by weight or more lead) Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices Electrical and electronic components containing lead in a glass or ceramic matrix compound, e.g. chip resistors

App. 15 Encoder output pulse setting method

For details of "Encoder output pulse setting selection" in [Pr. PC19], refer to the following table.

Setting value Servo motor/direct drive motor Linear servo motor _ _ 0 _

(Output pulse setting)

Set the output pulses per revolution with [Pr. PA15 Encoder output pulses]. Output pulse = a value set in [Pr. PA15] [pulse/rev] Selecting "Load side encoder (_ 1 _ _)" of "Encoder selection for encoder output pulse" in [Pr. PC19] triggers [AL. 37 Parameter error].

The output pulse setting cannot be used. If "0" is selected, the dividing ratio setting is used.

_ _1 _ (Dividing ratio

setting)

Set the dividing ratio to the resolution per servo motor revolution with [Pr. PA15 Encoder output pulses].

Output pulse = Resolution per revolution

[Pr. PA15] setting [pulse/rev]

Set the dividing ratio to the travel distance of the linear servo motor with [Pr. PA15 Encoder output pulses].

Output pulse = Travel distance of linear servo motor

[Pr. PA15] setting
