1. To prevent electric shock, note the following

WARNING Before wiring 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. 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.

In order to configure a circuit that shuts down the power supply on the side of the servo amplifiers power supply, always connect one molded-case circuit breaker or fuse per one servo amplifier between the power supply and the power supply (L1/L2/L3) of a servo amplifier. 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. Otherwise, a regenerative transistor malfunction or the like may overheat the regenerative resistor, causing smoke or a fire. Provide adequate protection to prevent screws and other conductive matter, oil and other combustible matter from entering the servo amplifier, servo motor, and MR-J4-T20. Always connect a molded-case circuit breaker to the power supply of the servo amplifier.

1. FUNCTIONS AND CONFIGURATION

POINT

Refer to chapter 14 for the MR-CR55K_ converter unit and MR-J4-DU_B_- RJ020 drive unit.

1.1 Summary

This Instruction Manual explains about the MR-J4-_B_-RJ020 AC servo amplifiers compatible with a conversion unit for SSCNET of MR-J2S-B, and the MR-J4-T20 conversion unit for SSCNET of MR-J2S-B. Always use MR-J4-T20 with MR-J4-_B_-RJ020. MR-J4-_B_-RJ020 can be connected to SSCNET of MR-J2S-B by being used with MR-J4-T20. MR-J4-_B_-RJ020 servo amplifiers have "J2S compatibility mode (factory setting)" and "J4 mode" as the operation mode. The "J2S compatibility mode" is the operation mode compatible with the previous functions of the MR-J2S-B series. This Instruction Manual explains when the "J2S compatibility mode" is used except for in chapter 13. When using the servo amplifier in "J4 mode", refer to chapter 13. When you use an MR-J4-_B_-RJ020 servo amplifier, please note the following items. (1) When an HG series servo motor is used in the J2S compatibility mode, the encoder resolution per servo

motor revolution will be 131072 pulses/rev (17 bits), not 4194303 pulses/rev (22 bits) (2) It may be required to change existing equipment program because the initialization time after power on

is different between MR-J2S-_B_ servo amplifier and MR-J4-_B_-RJ020 servo amplifier. Especially when using it in vertical motion applications, please be careful of electromagnetic brake release time. The moving part can fall.

(3) Motor-less operation cannot be used with MR Configurator. To use motor-less operation, set "_ 1 _ _" in

[Pr. 24]. (4) When using [Pr. 13 Position loop gain 1] of MR-J4-_B_-RJ020 and MR-J2S-_B_ simultaneously such as

in the interpolation mode, check droop pulses for each axis and readjust gains as necessary. (5) MR-J4-_B_-RJ020 servo amplifier is not compatible with adaptive vibration suppression control. (6) Power is not supplied from the SSCNET cable connection connector to the encoder. When using the

MR-J4-_B_-RJ020 servo amplifier in absolute position detection system, always connect a battery to the CN4 connector.

(7) When the servo amplifier is set to the J2S compatibility mode, it supports the fully closed loop system. In

the fully closed loop control mode, when an HG series servo motor is used for the load-side encoder, the resolution of the load-side encoder will be 131072 pulses/rev (17 bits), which is the same as that of the servo motor side. Refer to chapter 15 for details.

(2) Others

When using heat generating equipment such as the regenerative option, install them with full consideration of heat generation so that the servo amplifier is not affected. Install the servo amplifier on a perpendicular wall in the correct vertical direction.

2.2 Keep out foreign materials

(1) When drilling in the cabinet, prevent drill chips and wire fragments from entering the servo amplifier. (2) Prevent oil, water, metallic dust, etc. from entering the servo amplifier through openings in the cabinet or

a cooling fan installed on the ceiling. (3) When installing the cabinet in a place where toxic gas, dirt and dust exist, conduct an air purge (force

clean air into the cabinet from outside to make the internal pressure higher than the external pressure) to prevent such materials from entering the cabinet.

2.3 Encoder cable stress

(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 flexing radius should be made as large

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

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 will occur due to contact wear arisen from switching currents. Relays reach the end of their lives when the power has been turned on, forced stop by EM1 (Forced stop) has occurred, and controller forced stop has occurred 100,000 times in total, or when the STO has been turned on and off 1,000,000 times while the servo motor is stopped under servo-off state. However, the lives of relays may depend 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.

Use a noise filter, etc. to minimize the influence of electromagnetic interference. Electromagnetic interference may be given to the electronic equipment used near the servo amplifier.

Do not install a power capacitor, surge killer or radio noise filter (optional FR-BIF (-H)) with the power line of the servo motor.

When using the regenerative resistor, switch power off with the alarm signal. Otherwise, a transistor fault or the like may overheat the regenerative resistor, causing a fire.

Do not modify the equipment.

Connecting a servo motor of the incorrect axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.

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.

Switch main circuit power supply off at detection of an alarm on the controller side. 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 incorrect 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.

POINT

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-J2S series servo amplifier's. When using MR-J4 as a replacement for MR-J2S, be careful not to connect the power to L2.

Configure the wiring to shut off the main circuit power supply and turn off the servo-on command as soon as an alarm occurs, or the servo forced stop or controller forced stop is enabled. A molded-case circuit breaker (MCCB) must be used with the input cables of the main circuit power supply.

3.3.2 Power-on sequence

CAUTION

The following shows the initialization time (from turning on power until receiving servo-on command) of MR-J2S-_B_ servo amplifier and MR-J4-_B_-RJ020 servo amplifier.

MR-J2S-_B_: maximum of 3 s

MR-J4-_B_-RJ020: maximum of 4 s Therefore, please note the following items when replacing MR-J2S-_B_ servo amplifier with MR-J4-_B_-RJ020 servo amplifier.

When a release time of braking for preventing a drop of axis is adjusted with an external timer in a system which a moving part works vertically, the moving part can drop due to longer time until servo-lock. Please readjust the release time of braking or use MBR (Electromagnetic brake interlock).

The time from power on until the servo motor begins to work can be longer.

POINT

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

(1) Power-on procedure

1) Always wire the power supply as shown in section 3.1 using the magnetic contactor with the main circuit power supply (L1/L2/L3). Configure 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 control circuit power supply is turned on with the main circuit power supply off, and then the servo-on command is transmitted, [AL. E9 Main circuit off warning] will occur. Turning on the main circuit power supply stops the warning and starts the normal operation.

3) The servo amplifier receives the servo-on command within 3 s to 4 s after the main circuit power

supply is switched on. (Refer to (2) in this section.)

3.9 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.

4.2 Startup

Connect the servo motor with a machine after confirming that the servo motor operates properly alone. (1) Power on

When the main and control circuit power supplies are turned on, "b1" (for the first axis) appears on the servo amplifier display. When you use the absolute position detection system, first power-on results in [AL. 25 Absolute position erased] and the servo system cannot be switched on. The alarm can be deactivated by then switching power off once and on again. Also, if power is switched on at the servo motor speed of 3000 r/min or higher, position mismatch may occur due to external force or the like. Power must therefore be switched on when the servo motor is at a stop.

(2) Parameter setting

POINT

The following encoder cables are of four-wire type. When using any of these encoder cables, set [Pr. 23] to "_ 1 _ _" to select the four-wire type. Incorrect setting will result in [AL. 16 Encoder error 1]. MR-EKCBL30M-L MR-EKCBL30M-H MR-EKCBL40M-H MR-EKCBL50M-H MR-ESCBL30M-L MR-ESCBL30M-H MR-ESCBL40M-H MR-ESCBL50M-H

POINT

The control axis No. set to the axis selection rotary switch (SW1) should be the same as the one set to the servo system controller. The number of the axes you can set depends on the servo system controller.

For setting the axis selection rotary switch, use a flat-blade screwdriver with the blade edge width of 2.1 mm to 2.3 mm and the blade edge thickness of 0.6 mm to 0.7 mm.

Use the axis selection rotary switch (SW1) to set the control axis number for the servo. If the same numbers are set to different control axes in a single communication system, the system will not operate properly. The control axes may be set independently of the SSCNET cable connection sequence. Set the switch to "F" when performing the test operation mode by using MR Configurator.

alone in JOG operation of test operation mode

Test operation of the servo motor alone by commands

Test operation with the servo motor and machine connected

In this step, confirm that the servo amplifier and servo motor operate normally. With the servo motor disconnected from the machine, use the test operation mode and check whether the servo motor rotates correctly. Refer to section 4.5 for the test operation mode. In this step, confirm that the servo motor rotates correctly under the commands from the controller. Give a low speed command at first and check the rotation direction, etc. of the servo motor. If the machine does not operate in the intended direction, check the input signal. In this step, connect the servo motor with the machine and confirm that the machine operates normally under the commands from the controller. Give a low speed command at first and check the operation direction, etc. of the machine. If the machine does not operate in the intended direction, check the input signal. Check any problems with the servo motor speed, load ratio, and other status display items with MR Configurator. Then, check automatic operation with the program of the controller.

4.5 Test operation mode

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 servo motor alone.

If the servo motor operates abnormally, use EM1 (Forced stop) to stop it.

POINT

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

By using a personal computer and MR Configurator, you can execute JOG operation, positioning operation, DO forced output program operation without connecting the servo system controller.

5. PARAMETERS

CAUTION

Never make a drastic adjustment or change to the parameter values as doing so will make the operation unstable.

Do not change the parameter settings as described below. Doing so may cause an unexpected condition, such as failing to start up the servo amplifier.

Changing the values of the parameters for manufacturer setting

Setting a value out of the range

Changing the fixed values in the digits of a parameter

When you write parameters with the controller, make sure that the control axis No. of the servo amplifier is set correctly. Otherwise, the parameter settings of another axis may be written, possibly causing the servo amplifier to be an unexpected condition.

POINT

When you connect the amplifier to a servo system controller, servo parameter values of the servo system controller will be written to each parameter.

Setting may not be made to some parameters and their ranges depending on the servo system controller model, servo amplifier software version, and MR Configurator software version. For details, refer to the servo system controller user's manual.

Changing operation mode initializes parameters. When operation mode is changed, make gain adjustment again.

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. 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 using [Pr. 13 Position loop gain 1] of MR-J4-_B_-RJ020 and MR-J2S-_B_ simultaneously such as in the interpolation mode, check droop pulses for each axis and readjust gains.

6.1 Different adjustment methods

6.1.1 Adjustment on a single servo amplifier

The following 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", "Manual mode 1" and "Manual mode 2" in this order. (1) Gain adjustment mode explanation

Used when the condition of "Auto tuning mode 1" is not satisfied or the load to motor inertia ratio could not be estimated properly.

This mode permits adjustment easily with three gains if you were not satisfied with auto tuning results.

You can adjust all gains manually when you want to do fast settling or the like.

6.1.2 Adjustment using MR Configurator

POINT

When using the machine analyzer, set the axis No. of servo amplifier to "F". (Refer to section 4.3.1.)

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

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. You can automatically set the optimum gains in response to the machine characteristic. This simple adjustment is suitable for a machine which has large machine resonance and does not require much settling time.

6.2 Auto tuning

6.2.1 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 "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 "Auto tuning mode 1".

Parameter Symbol Name

12 GD2 Ratio of load inertia to servo motor inertia (load inertia ratio)

13 PG1 Position loop gain 1

14 VG1 Speed loop gain 1

15 PG2 Position loop gain 2

16 VG2 Speed loop gain 2

17 VIC Speed integral compensation

POINT

"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 is 5 s or less.

Speed is 150 r/min or higher.

The load to 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 "Auto tuning mode 2", "Manual mode 1" or "Manual mode 2" to make gain adjustment.

6. NORMAL GAIN ADJUSTMENT

6 - 4

(2) Auto tuning mode 2

Use "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. 12]. The following parameters are automatically adjusted in "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. 12 Ratio of load inertia to servo motor inertia (load inertia ratio). These results can be confirmed on the status display screen of the MR Configurator. 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 (_ _ _ 3)" in [Pr. 8] to stop the estimation (turning off the switch in the above diagram), and set the load to motor inertia ratio ([Pr. 12]) manually. From the preset load to motor inertia ratio ([Pr. 12]) value and response ([Pr. 9]), the optimum loop gains are automatically set on the basis of the internal gain table. The auto tuning results are saved in the motion controller about every 10 s since power-on. At power-on, auto tuning is performed with the value of each loop gain saved in the motion controller being used as an initial value.

6. NORMAL GAIN ADJUSTMENT

6 - 5

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 (_ _ _ 3)" in [Pr. 8] and then set the correct load to motor inertia ratio in [Pr. 12].

When any of "Auto tuning mode 1", "Auto tuning mode 2" or "Manual mode 1" settings is changed to the manual mode setting, the current loop gains and load to motor inertia ratio estimation value are saved in the EEP-ROM.

6.2.3 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 adjustment

Acceleration/deceleration repeated

Auto tuning conditions not satisfied?

(Estimation of load to motor inertia ratio is difficult)

Load to motor inertia ratio estimation value stable?

Set [Pr. 08] to "_ _ _ 3" and set [Pr. 12 Ratio of load inertia to servo motor inertia (load inertia ratio)] manually.

6.2.4 Response level setting in auto tuning mode

Set the response of the whole servo system by [Pr. 9]. As the response level setting is increased, the 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, [Pr. 18 Machine resonance suppression filter 1 (notch filter)] may be used to suppress machine resonance. Suppressing machine resonance may allow the response level setting to increase. For changing the setting value of the machine resonance suppression filter, refer to 7.1.1.

6.3 Manual mode 1 (simple manual adjustment)

If you are not satisfied with the adjustment of auto tuning, you can adjust all gains manually.

POINT

If the machine resonance occurs, you can suppress the machine resonance with [Pr. 18 Machine resonance suppression filter 1 (notch filter)]. (Refer to section 7.1.1.)

6.3.1 Manual mode 1 basis

In this mode, setting of three gains of PG1 (position loop gain 1), VG2 (speed loop gain 2) and VIC (speed integral compensation) automatically sets the other gains to the optimum values according to these gains.

PG1 VG2 VIC

PG2 VG1Automatic setting

GD2 User setting

Therefore, you can adjust the model adaptive control system in the same image as the general PI control systems (position gain, speed gain and speed integral time constant). Here, the position corresponds to PG1, speed gain to VG2 and speed integral compensation time constant to VIC. When you adjust the gain with this mode, set [Pr. 12 Ratio of load inertia to servo motor inertia (load inertia ratio)] properly. 6.3.2 Adjustment by manual mode 1

Step Operation Description

1 Brief-adjust with auto tuning. Refer to section 6.2.3.

2 Change the setting of auto tuning to the manual mode 2 ([Pr. 8]: _ _ _ 2).

3 Set an estimated value in [Pr. 12 Ratio of load inertia to servo motor inertia (load inertia ratio)].

Increase the speed loop gain.

5 Decrease the [Pr. 17 Speed integral compensation] within the vibration-free range, and return slightly if vibration takes place.

Decrease the time constant of the speed integral compensation.

6

If the gains cannot be increased due to mechanical system resonance or the like and the desired response cannot be achieved, response may be increased by suppressing resonance with the machine resonance suppression filter and then executing steps 4 and 5.

(c) Parameter adjustment

1) [Pr. 16 Speed loop gain 2] This parameter determines the response level of the speed control loop. Increasing the setting increases the response level, but the mechanical system is liable to vibrate. The actual response frequency of the speed loop is as indicated in the following expression.

Speed loop response frequency [Hz] = (1 + Load to motor inertia ratio) 2

Speed loop gain 2

2) [Pr. 17 Speed integral compensation]

To eliminate stationary deviation against a command, the speed control loop is under proportional integral control. For the speed integral compensation, set the time constant of this integral control. Increasing the setting lowers the response level. However, if the load to motor inertia ratio is large or the mechanical system has any vibratory element, the mechanical system is liable to vibrate unless the setting is increased to some degree. The guideline is as indicated in the following expression.

However, if the load to motor inertia ratio is large or the mechanical system has any vibratory element, the mechanical system is liable to vibrate unless the setting is increased to some degree. The guideline is as indicated in the following expression.

Speed integral compensation setting [ms] 2000 to 3000

Speed loop gain 2/(1 + Load to motor inertia ratio)

3) [Pr. 13 Position loop gain 1]

This parameter determines the response level to a disturbance to the position control loop. Increasing the position loop gain 1 increases the response level to a disturbance, but the mechanical system is liable to vibrate.

1 Set the auto tuning mode 1 ([Pr. 8: _ _ _ 1]) and machine resonance frequency of response level to 15 Hz ([Pr. 9: _ _ _ 1]).

Select the auto tuning mode 1.

2 During operation, increase the response level setting value in [Pr. 9], and return the setting if vibration occurs.

3 Check the values of [Pr. 13 Position loop gain 1] and [Pr. 14 Speed loop gain 1].

Check the upper setting limits.

4 Set to the interpolation mode ([Pr. 8: _ _ _ 0]). Select the interpolation

mode.

5 Set the position loop gain 1 of all the axes to be interpolated to the same value. At that time, adjust to the setting value of the axis, which has the smallest position loop gain 1.

Set the position loop gain 1.

Considering the speed loop gain 1 value you checked in step 3 as an upper limit guideline, set not less than three times the position loop gain 1 setting value while checking the servo motor movement.

Set the speed loop gain 1.

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 depth 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 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 Configurator. 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 can suppress the resonance of the mechanical system.

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) and gain decreasing depth.

7.1.2 Low-pass filter

POINT

In a mechanical system with extremely high rigidity where resonance is difficult to occur, setting the low-pass filter to "Disabled" may increase the servo system response to shorten the settling time.

(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 the initial value. The filter frequency of the low-pass filter is automatically adjusted to the value in the following equation.

Filter frequency (Hz) = Speed loop gain 2 setting value 10

7.1.3 Adaptive vibration suppression control function

The adaptive vibration suppression control function is a function where the servo amplifier detects mechanical resonance and sets filter characteristics automatically to suppress mechanical vibration. The MR-J4-_B_-RJ020 servo amplifier has an adaptive vibration suppression control function different from that of the MR-J2S-_B_ servo amplifier. You can set filter characteristics with the adaptive filter II (adaptive tuning) or vibration tough drive function, both of which are equivalent to those of the MR-J4-_B_(-RJ) servo amplifier. (1) 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 s 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.

Adaptive vibration suppression control may provide no effect on a mechanical system which has complex resonance characteristics.

Unlike the MR-J2S-_B_, the MR-J4-_B_-RJ020 supports the adaptive filter II (adaptive tuning) equivalent to that of the MR-J4-_B_. However, only the standard mode is available for the tuning accuracy.

Adaptive filter II (adaptive tuning) is a function in which the servo amplifier detects machine resonance 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.

(2) 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. The vibration tough drive function operates when the detected machine resonance frequency is within 30% of that detected in adaptive tuning.

POINT

The vibration tough drive function continuously resets the machine resonance frequency. However, the data is written to the EEP-ROM once per hour.

The vibration tough drive function does not detect a vibration of 100 Hz or less.

When "Enabled (_ 1 _ _)" is set in [Pr. 25 (_ x _ _)], the vibration tough drive function resets the machine resonance frequency.

When the servo amplifier is removed and installed to a different machine, set "Disabled (_ 0 _ _)" in [Pr. 25 (_ x _ _)] to initialize the filter characteristics.

7.2 Gain switching function

You can switch gains with the function. You can switch gains during rotation and during stop, and can use a control command from a controller 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 a control command from a controller 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).

8.2 Remedies for alarms

CAUTION

When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before restarting operation. Otherwise, it may cause injury.

If [AL. 25 Absolute position erased] occurs, always make home position setting again. Otherwise, it may cause an unexpected operation.

As soon as an alarm occurs, set the servo amplifier to the servo-off status and interrupt the main circuit power.

POINT

When any of the following alarms has occurred, do not deactivate the alarm to restart. Doing so will cause a malfunction of the servo amplifier and servo motor. Remove its cause and allow about 30 minutes for cooling before resuming the operation. To protect the main circuit elements, any of these alarms cannot be deactivated from the servo system controller until the specified time elapses after its occurrence. Judging the load changing condition until the alarm occurs, the servo amplifier calculates this specified time automatically.

[AL. 30 Regenerative error] [AL. 50 Overload 1]

10. CHARACTERISTICS

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 an 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-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 a servo motor overload protective function. (The servo motor overload current (full load current) is set on the basis of 115% rated current of the servo amplifier.) The following table shows combinations of each servo motor and graph of overload protection characteristics.

Note 1. If an 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 30 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.

(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 T

P (10.1)

A: Heat dissipation area [m2] P: Loss generated in the cabinet [W] T: Difference between the internal and ambient temperatures [C] K: 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 lists the cabinet dissipation area for each servo amplifier (guideline) when the servo amplifier is operated at the ambient temperature of 40 C under rated load.

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

POINT

Do not use the 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) after servo motor stops when using EM1 (Forced stop) 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. 39] and [Pr. 56].

When an HG series servo motor is used with a servo amplifier of 11 kW or more, use the external dynamic brake for MR-J4. The external dynamic brake for MR- J2S cannot be used.

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

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.

Since large inrush currents flow in the power supplies, always use molded-case circuit breakers and magnetic contactors. (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 table indicates the inrush current (reference data) that will flow when 240 V AC is applied to the servo amplifier with the power supply capacity of 2500 kVA and the wiring length of 1 m. Even when you use a 1-phase 200 V AC power supply with MR-J4-10B-RJ020 to MR-J4-70B-RJ020, the inrush current of the main circuit power supply will be 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 peripheral 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.

The CN1A and CN1B connectors are not used in the J2S compatibility mode. Always put caps came with the servo amplifier.

The CN8 connector is not used in the J2S compatibility mode. Always attach the short-circuit connector came with the servo amplifier.

For connecting the servo amplifier with the HG series servo motor, refer to "Servo Motor Instruction Manual (Vol. 3)".

Please purchase the cable and connector options indicated in this section.

Inverse efficiency (m): Efficiency including some efficiencies of the servo motor and servo amplifier

when the rated (regenerative) torque is generated at the 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.

ER [J] = m Es - Ec

Calculate the power consumption of the regenerative option on the basis of one-cycle operation period tf [s] to select the necessary regenerative option.

For the wire sizes used for wiring, refer to section 11.9.

The regenerative option generates heat of 100 C higher than the ambient temperature. Fully consider heat dissipation, installation position, wires used, etc. before installing the option. For wiring, use flame-resistant wires or make the wires flame-resistant and keep them away from the regenerative option. Use twisted wires with a maximum length of 5 m for a connection with the servo amplifier. (1) MR-J4-500B-RJ020 or less/MR-J4-350B4-RJ020 or less

Always remove the wiring across P+ and D and fit the regenerative option between P+ and C. G3 and G4 are terminals for a thermal sensor. The connection between G3 and G4 is opened when the regenerative option overheats abnormally.

the 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 (92 92, minimum air flow: 1.0 m3) improves the regeneration capability. In this case, set "_ _ 0 E" in [Pr. 2].

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

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.

The temperature of the resistor unit case will be higher than the ambient temperature by 100 C or over. Keep cables and flammable materials away from the case.

The ambient temperature condition for the brake unit is between -10 C and 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.

For executing a continuous regenerative operation, use the FR-RC-(H) power regeneration converter or FR-CV-(H) power regeneration common converter.

Brake unit and regenerative options (Regenerative resistor) cannot be used simultaneously.

11. OPTIONS AND PERIPHERAL EQUIPMENT

11 - 27

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 "_ _ 0 1" in [Pr. 2]. When using the brake unit, always refer to "FR-BU2 Brake Unit Instruction Manual". 11.3.1 Selection

11.11 Power factor improving DC reactor

The following shows the advantages of using the 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 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 the wiring between P3 and P4. If they remain 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. (1) 200 V class

11.12 Power factor improving AC reactor

The following shows the advantages of using the 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 about 80%. When using power factor improving reactors for two or more servo amplifiers, 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/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 equipment 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 equipment 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 3.9.)

(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 killers 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 equipment 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 equipment located near the main circuit cables, and those transmitted through the power supply cables.

Noises produced by servo amplifier

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 cable 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 circuit 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 circuit 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. Noise-reducing effect will be enhanced.

Ig1 Iga Ig2 Igm

Servo amplifier MR-J4-40B-RJ020

Use an earth-leakage current breaker designed for suppressing harmonics/surges. Find the terms of equation (11.1) from the diagram.

Ig1 = 20 5

1000 = 0.1 [mA]

Ig2 = 20 5

1000 = 0.1 [mA]

Ign = 0 (not used)

Iga = 0.1 [mA]

Igm = 0.1 [mA]

Insert these values in equation (11.1).

Ig 10 {0.1 + 0 + 0.1 + 1 (0.1 + 0.1)} 4 [mA]

According to the result of calculation, use an earth-leakage current breaker having the rated sensitivity current (Ig) of 4.0 mA or more. An earth-leakage current breaker having Ig of 15 mA is used with the NV-SP/SW/CP/CW/HW series.

11.17 External dynamic brake

CAUTION

Use an external dynamic brake for a servo amplifier of MR-J4-11KB-RJ020 to MR-J4-22KB-RJ020/MR-J4-11KB4-RJ020 to MR-J4-22KB4-RJ020. 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.

POINT

Configure a sequence which switches off the magnetic contactor of the external dynamic brake after (or as soon as) servo-on command has been turned off at a power failure or a malfunction.

For the braking time taken when the 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).

When an alarm, [AL. E6 Servo forced stop warning], or [AL. E6 Controller forced stop warning] occurs, or the power is turned off, the external dynamic brake will operate. 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) after servo motor stops when using EM1 (Forced stop) 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. Set [Pr. 2] to "_ 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 12.5 for the replacement procedure of the battery.

For configuring the absolute position detection system, there are three batteries of MR-BAT6V1SET, MR-BAT6V1BJ and MR-BT6VCASE. Compared with other batteries, MR-BAT6V1BJ has the following advantages.

You can disconnect the encoder cable from the servo amplifier.

You can change 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. When an MR-BAT6V1SET and MR-BT6VCASE are used...

The encoder cable was disconnected.

The battery was replaced when the control circuit power supply was off. When an MR-BAT6V1BJ is used...

A connector or cable was disconnected between the servo motor and battery.

The battery was replaced with procedures other than those of (3) in section 11.8.3.

MR-BAT6V1BJ is only for the HG series servo motors.

Power is not supplied from the SSCNET cable connection connector to the encoder. When using the servo amplifier in absolute position detection system, always connect a battery to the CN4 connector.

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 servo system 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.

selected for "operation mode".

(4) Press "Write". (5) Cycling the power of the servo amplifier or drive unit switches the mode to the J2S compatibility mode. 13.2 Parameter

CAUTION

Never make a drastic adjustment or change to the parameter values as doing so will make the operation unstable.

Do not change the parameter settings as described below. Doing so may cause an unexpected condition, such as failing to start up the servo amplifier.

Changing the values of the parameters for manufacturer setting

Setting a value out of the range

Changing the fixed values in the digits of a parameter

When you write parameters with the controller, make sure that the control axis No. of the servo amplifier is set correctly. Otherwise, the parameter settings of another axis may be written, possibly causing the servo amplifier to be an unexpected condition.

POINT

When you connect the amplifier to a servo system controller, servo parameter values of the servo system controller will be written to each parameter.

Setting may not be made to some parameters and their ranges depending on the servo system controller model, servo amplifier software version, and MR Configurator2 software version. For details, refer to the servo system controller user's manual. Check the software version of the servo amplifier or drive unit using MR Configurator2.

13.3 Troubleshooting

POINT

Refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)" for details of alarms and warnings.

As soon as an alarm occurs, make the Servo-off status and interrupt the main circuit power.

[AL. 37 Parameter error] and warnings (except [AL. F0 Tough drive warning]) are not recorded in the alarm history.

When an error occurs during operation, the corresponding alarm and warning are displayed. When an alarm or warning is displayed, refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)" to remove the failure. When an alarm occurs, ALM will turn off. 13.3.1 Explanation for the lists

(1) No./Name/Detail No./Detail name Indicates each No./Name/Detail No./Detail name of alarms or warnings.

(2) Stop method

For the alarms and warnings in which "SD" is written in the stop method column, the servo motor stops with the dynamic brake after forced stop deceleration. For the alarms and warnings in which "DB" or "EDB" is written in the stop method column, the servo motor stops with the dynamic brake without forced stop deceleration.

(3) Alarm deactivation

After cause of the alarm has been removed, the alarm can be deactivated by any of the methods marked in the alarm deactivation column. Warnings are automatically canceled after the cause of occurrence is removed. Alarms are deactivated with alarm reset, CPU reset, or cycling the power.

Alarm deactivation Explanation

Alarm reset 1. Reset command from controller 2. Click the "Occurring Alarm Reset" in the "Alarm Display" window of MR

Configurator2

CPU reset Resetting the controller itself

Cycling the power Turning the power off and then turning it on again.

14.1.1 Summary

This section explains MR-J4-DU_B_-RJ020 drive unit compatible with conversion unit for SSCNET of MR- J2S-B and MR-J4-T20 conversion unit for SSCNET of MR-J2S-B. Always use MR-J4-T20 with MR-J4-DU_B_-RJ020. Using MR-J4-T20 with an MR-J4-DU_B_-RJ020 enables the MR-J4-DU_B_-RJ020 to connect to SSCNET of MR-J2S-B. MR-J4-DU_B_-RJ020 drive unit has "J2S compatibility mode (factory setting)" and "J4 mode" as the operation mode. "J2S compatibility mode" is the operation mode compatible with the previous functions of MR-J2S-B series. This section explains a case where the drive unit is used in "J2S compatibility mode". When using it in "J4 mode", refer to chapter 13. When you use an MR-J4-DU_B_-RJ020 drive unit, please note the following items. (1) When an HG series servo motor is used in the J2S compatibility mode, the encoder resolution per servo

motor revolution will be 131072 pulses/rev (17 bits), not 4194303 pulses/rev (22 bits). (2) It may be required to change existing equipment program because the initialization time after power on

is different between MR-J2S-_B_ servo amplifier and MR-J4-DU_B_-RJ020 drive unit. Especially when using it in vertical motion applications, please be careful of electromagnetic brake release time. The moving part may fall.

(3) Motor-less operation cannot be used with MR Configurator. To use motor-less operation, set "_ 1 _ _" in

[Pr. 24]. (4) When using [Pr. 13 Position loop gain 1] of MR-J4-DU_B_-RJ020 and MR-J2S-_B_ simultaneously such

as in the interpolation mode, check droop pulses for each axis and readjust gains as necessary. (5) MR-J4-DU_B_-RJ020 drive unit is not compatible with adaptive vibration suppression control. (6) Power is not supplied from the SSCNET cable connection connector to the encoder. When using it in

absolute position detection system, always connect a battery to the CN4 connector of the MR-J4- DU_B_-RJ020 drive unit.

(7) When the servo amplifier is set to the J2S compatibility mode, it supports the fully closed loop system. In

the fully closed loop control mode, when an HG series servo motor is used for the load-side encoder, the resolution of the load-side encoder will be 131072 pulses/rev (17 bits), which is the same as that of the servo motor side. Refer to chapter 15 for details.

Note 1. For specifications of the cooling fan power supply, refer to "Servo Motor Instruction Manual (Vol. 3)".

2. Use an external dynamic brake for the drive unit. 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. For wiring of the external dynamic

brake, refer to section 14.9.3.

3. This is not used when the drive unit is in the J2S compatibility mode. Always attach the short-circuit connector came with the

14.2.4 Parts having service life

Service life of the following parts is listed below. However, the service life varies 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 local sales office.

Part name Life guideline

Smoothing capacitor 10 years

Relay Number of power-on, forced stop by EM1

(Forced stop 1), controller forced stop, and on/off for STO: 100,000 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 will occur due to contact wear arisen from switching currents. Relays reach the end of their lives when the number of power-on, forced stop by EM1 (Forced stop 1), controller forced stop, and on/off for STO while the servo motor is stopped under servo-off state reaches 100,000 times. However, the lives of relays may depend on the power supply capacity.

(3) Cooling fan

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

Item Detailed explanation

I/O signal connection example Section 3.2

14.3.1 Input power supply circuit

WARNING

Insulate the connections of the power supply terminals. Otherwise, an electric shock may occur.

Always connect the magnetic contactor wiring connector to CNP1 of the converter unit. If the connector is not connected, an electric shock may occur.

CAUTION

Always connect the magnetic contactor between the power supply and the main circuit power supply (L1/L2/L3) of the converter unit, in order to configure a circuit that shuts down the power supply on the side of the converter unit power supply. If the magnetic contactor is not connected, a large current keeps flowing and may cause a fire when the converter unit or the drive unit malfunctions.

Switch main circuit power supply off at detection of an alarm on the controller side. Not doing so may cause a fire when a regenerative transistor malfunctions or the like may overheat the regenerative resistor.

The converter unit 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.

Do not connect the servo motor of a wrong axis to U, V, W, or CN2 of the drive unit. Otherwise, a malfunction may occur.

Check the converter unit model, and then input proper voltage to the converter unit power supply. If input voltage exceeds the upper limit, the converter unit and the drive unit will break down.

(1) Magnetic contactor control connector (CNP1)

CAUTION Always connect the magnetic contactor wiring connector to the converter unit. If the connector is not connected, an electric shock may occur since CNP1-1 and L11 are always conducting.

By enabling magnetic contactor drive output, the main circuit power supply can be shut off automatically when an alarm occurs in the converter unit or the drive unit. To enable magnetic contactor drive output, set [Pr. PA02] of the converter unit to "_ _ _ 1" (initial value).

Note 1. A step-down transformer is required when coil voltage of the magnetic contactor is

200 V class, and the converter unit and the drive unit are 400 V class.

2. When the voltage between L11 and L21 drops due to an instantaneous power

failure and others, the magnetic contactor is turned off.

When the converter unit receives a start command from the drive unit, CNP1-2 and L21 are shorted, and the control circuit power is supplied to the magnetic contactor. When the control circuit power is supplied, the magnetic contactor is turned on, and the main circuit power is supplied to the converter unit. In the following cases, CNP1-2 and L21 in the converter unit are opened, and the main circuit power supply is automatically shut off.

1) An alarm occurred in the converter unit.

2) An alarm occurred in the drive unit.

3) The forced stop (EM1) of the converter unit was disabled.

4) [AL. E6 Servo forced stop warning] occurred in the drive unit.

(b) When magnetic contactor drive output is disabled

The main circuit power supply is not automatically shut off even when an alarm occurs in the converter unit or the drive unit. Therefore, configure an external circuit to shut off the main circuit power supply when detecting an alarm.

14.8.1 Overload protection characteristics

(1) Converter unit An electronic thermal is built in the converter unit to protect the converter unit from overloads. [AL. 50 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve shown in fig. 14.1. [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 graph.

(2) Drive unit

An electronic thermal is built in the drive unit to protect the servo motor, drive unit 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. 14.2. [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 lower of the motor's rated torque. The drive unit has the servo motor overload protective function. (The servo motor overload current (full load current) is set on the basis of 120% rated current of the drive unit.)

an abnormally high frequency in a servo motor stop status (servo-lock status) or

in a 30 r/min or less low-speed operation status, the drive unit may malfunction

regardless of the electronic thermal protection.

14.8.2 Power supply capacity and generated loss

(1) Generated heat of the converter unit/drive unit Table 14.1 indicates the generated loss and power supply capacity under rated load per combination of the converter unit and drive unit. When the servo motors are run at less than the rated speed, the power supply equipment capacity is lower than the value in the table but the heat generated does not change. Since the servo motor requires 2 times to 2.5 times greater instantaneous power for acceleration, use the power supply which ensures that the voltage lies within the permissible voltage fluctuation at the main circuit power supply terminals (L1/L2/L3) of the converter unit. The power supply equipment capacity changes with the power supply impedance. The actually generated heat falls within the ranges at rated output and at servo-off according to the frequencies of use during operation. When designing an enclosed cabinet, use the values in the table, considering the worst operating conditions. The generated heat in table 14.1 does not include heat produced during regeneration.

The enclosed type cabinet (hereafter called the cabinet) which will contain the converter unit and drive unit 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 14.1.

A = K T

P (14.1)

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

When calculating the heat dissipation area with equation 14.1, assume that P is the sum of all losses generated in the cabinet. Refer to table 14.1 for the generated heat of the converter unit/drive unit. "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 14.1 lists the cabinet dissipation area (guideline) when the converter unit and drive unit are operated at the ambient temperature of 40 C under rated load.

(Outside the cabinet) (Inside the cabinet)

Air flow

Fig. 14.3 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.

14.8.3 Dynamic brake characteristics

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.

When an HG series servo motor is used with the drive unit, use the external dynamic brake for MR-J4. The external dynamic brake for MR-J2S cannot be used.

(1) Dynamic brake operation

(a) Calculation of coasting distance Fig. 14.4 shows the pattern in which the servo motor comes to a stop when the dynamic brake is operated. Use equation 14.2 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 (b) of 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.

There is delay caused by magnetic contactor built into the external dynamic brake (about 50 ms) and delay caused by the external relay.

(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 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 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.

14.8.4 Inrush currents at power-on of main circuit/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, always use molded-case circuit breakers and magnetic contactors. (Refer to section 14.9.5.) 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 table indicates the inrush currents (reference data) that will flow when 240 V AC is applied at the power supply capacity of 2500 kVA and the wiring length of 1 m.

14.9 Options and peripheral equipment

WARNING

Before connecting any option or peripheral equipment, turn off the power and wait for 20 minutes or more until the charge lamp turns off. Then, confirm that the voltage between L+ and L- is safe with a voltage tester and others. Otherwise, an electric shock may occur. In addition, always confirm whether the charge lamp is off or not from the front of the converter unit.

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

POINT

We recommend using HIV wires to wire the converter units, drive units, options, and peripheral equipment. Therefore, the recommended wire sizes may different from those of the used wires for the previous converter units, drive units and others.

Inverse efficiency (): Efficiency including some efficiencies of the servo motor and drive unit 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 converter unit

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.

The regenerative option generates heat of 100 C higher than the ambient temperature. Fully consider heat dissipation, installation position, wires used, etc. before installing the option. For wiring, use flame- resistant wires or make the wires flame-resistant and keep them away from the regenerative option. The G3 and G4 terminals act as a thermal protector. Between G3 and G4 is opened when the regenerative option overheats abnormally. Use twisted wires with a maximum length of 5 m for a connection with the converter unit.

14.9.3 External dynamic brake

CAUTION

Use an external dynamic brake for this drive unit. 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.

POINT

Configure a sequence which switches off the magnetic contactor of the external dynamic brake after (or as soon as) servo-on command 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 14.8.3.

The external dynamic brake is rated for a short duration. Do not use it very frequently.

The specifications of the input power supply for external dynamic brake are the same as those of the converter unit control circuit power supply.

When an alarm, [AL. E6 Servo forced stop warning], or [AL. E7 Controller forced stop warning] occurs, or the power is turned off, the external dynamic brake will operate. 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 external dynamic brake is designed to bring the servo motor to a sudden stop when a power failure occurs or the protective circuit is activated.

Note 1. Terminals 13 and 14 are normally open contact outputs. If the dynamic brake is seized, terminals 13 and 14 will open. Therefore, configure an external sequence to prevent servo-on.

2. Step-down transformer is required when coil voltage of the magnetic contactor is 200 V class, and the converter unit and the drive unit are 400 V class.

3. To enable DB (Dynamic brake interlock), set [Pr. 2] to "_ 1 _ _". 4. For power supply specifications, refer to section 14.1.3. 5. 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, delay the time to turn off the magnetic contactor.

6. Turn off EM1 when the main circuit power supply is off. 7. Install an overcurrent protection device (molded-case circuit breaker, fuse, or others) to protect the branch circuit. (Refer to

section 14.9.5 and (1) in this section.) 8. Configure the power supply circuit which turns off the magnetic contactor after detection of alarm occurrence on the controller

side.

14.9.6 Power factor improving DC reactor

The following shows the advantages of using power factor improving DC reactor.

It improves the power factor by increasing the form factor of the converter unit's input current.

It decreases the power supply capacity.

The input power factor is improved to about 95%. When connecting the power factor improving DC reactor to the converter unit, be sure to remove the short bar across P1 and P2. 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.

14.9.7 Noise reduction techniques

Noises are classified into external noises which enter the converter unit and drive unit to cause them to malfunction and those radiated by the converter unit and drive unit to cause peripheral equipment to malfunction. Since the converter unit and drive unit are electronic devices which handle small signals, the following general noise reduction techniques are required. Also, the drive unit can be a source of noise as its outputs are chopped by high carrier frequencies. If peripheral equipment malfunctions due to noise generation, take noise suppression measures. 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 of the converter unit/drive unit 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 converter unit, drive unit and the servo motor, etc. together at one point. (Refer to section 3.7.)

(b) Reduction techniques for external noises that cause the converter unit/drive unit 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 converter unit and drive unit and the converter unit/drive unit may malfunction, the following countermeasures are required.

Provide surge killers 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 converter unit, to protect the converter unit, drive unit and other equipment against large exogenous noise and lightning surge, attaching a varistor to the power input section of the equipment is recommended.

14 - 99

(c) Techniques for noises radiated by the converter unit/drive unit that cause peripheral equipment to

malfunction Noises produced by the converter unit and drive unit are classified into those radiated from the cables connected to the converter unit, drive unit and their main circuits (input and output circuits), those induced electromagnetically or statically by the signal cables of the peripheral equipment located near the main circuit cables, and those transmitted through the power supply cables.

Noises produced by converter unit and drive unit

Noises transmitted in the air

Noise radiated directly from converter unit and drive unit

Magnetic induction noise

Static induction noise

Noises transmitted through electric channels

Noise radiated from the power supply cable

Noise radiated from servo motor cable

Suppression techniques

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 converter unit and drive unit or run near the converter unit and drive unit, 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 converter unit/drive unit. 2. Provide maximum clearance between easily affected signal cables and the I/O cables of the

converter unit/drive unit. 3. Avoid wiring the power lines (input/output lines of the converter unit/drive unit) 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 signal and power lines or put 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 converter unit/drive unit. 2. Provide maximum clearance between easily affected signal cables and the I/O cables of the

converter unit/drive unit. 3. Avoid wiring the power lines (input/output lines of the converter unit/drive unit) and signal lines

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

7)

When the power supply of peripheral equipment is connected to the power supply of the converter unit/drive unit systems, noises produced by the converter unit and drive unit 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 converter unit/drive

unit. 2. Install the line noise filter (FR-BSF01/FR-BLF) on the power lines of the converter unit/drive unit.

8) When the grounding wires of peripheral equipment are connected to the converter unit/drive unit to make a closed loop circuit, leakage current may flow to malfunction the peripheral equipment. If so, malfunction may be prevented by disconnecting the grounding cable of the peripheral device.

14 - 101

(2) Noise reduction techniques

The following explains how to use the line noise filter unique to the converter unit and drive unit. Other noise reduction techniques are the same as those of MR-J4-_B_-RJ020. Refer to section 11.14 (2).

(a) Line noise filter (FR-BLF)

This filter is effective in suppressing noises radiated from the power supply side and output side of the converter unit, drive unit and also in suppressing high-frequency leakage current (0-phase current). It especially affects the noises between 0.5 MHz and 5 MHz band. The filters are used with the main circuit power supply of the converter unit (L1/L2/L3) and the power output of the drive unit (U/V/W).

1) Usage

Pass the 3-phase wires through four line noise filters. When you use the line noise filters with the power wires, passing the power wires together with the ground wire will reduce the filter effect. Run the ground wire separately from the power wires.

Use four FR-BLFs.

14.9.8 Earth-leakage current breaker

(1) Selection method High-frequency chopper currents controlled by pulse width modulation flow in the AC servo circuits. Leakage currents containing harmonic contents are larger than those of the motor which is run with a commercial power supply. Select an earth-leakage current breaker according to the following formula, and ground the drive unit, servo motor, etc. securely. To minimize leakage currents, make the input and output wires as short as possible, and keep a distance of 30 cm or longer between the wires and ground.

14.9.10 FR-BU2-(H) Brake Unit

POINT

Use a 200 V class brake unit and a resistor unit with a 200 V class converter unit, and a 400 V class brake unit and a resistor unit with a 400 V class converter unit. 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.

The temperature of the resistor unit case will be higher than the ambient temperature by 100 C or over. Keep cables and flammable materials away from the case.

Ambient temperature condition of the brake unit is between -10 C and 50 C. Note that the condition is different from the ambient temperature condition of the converter unit (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 14.9.10 (1).

Brake unit and regenerative options (Regenerative resistor) cannot be used simultaneously.

When using the brake unit, set the parameters as follows. Parameter Setting value

[Pr. PA01 Regenerative option] of the converter unit

_ _ 0 0 (initial value)

[Pr. 2 Regenerative resistor] of the drive unit _ _ 0 1

Connect the brake unit to the bus of the converter unit (L+ and L- of TE2-1) for use. 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, always refer to "FR-BU2 Brake Unit Instruction Manual". (1) Selection

15. FULLY CLOSED LOOP SYSTEM

POINT

The fully closed loop system is enabled only in J2S compatibility mode.

For the fully closed loop system, use the servo amplifier or the drive unit with following software version:

A4 or later for 7 kW or less

A6 or later for 11 kW or more

In the fully closed loop system, the following cable can be used for the servo motor encoder:

Two-wire type for software version A4 or later

Two-wire and four-wire types for software version A6 or later

When the fully closed loop system is used with this servo amplifier, "Linear Encoder Instruction Manual" is needed.

The fully closed loop system is available only in the position control mode.

When using the fully closed loop system, change the mode to "fully closed loop control mode" by using the application "MR-J4(W)-B mode selection" came with MR Configurator2.

Controller

Note 1. Switching between semi closed loop control and fully closed loop control can be performed by changing the setting of [Pr. 62].

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. 62], dual feedback control in which the servo motor feedback signal and

load-side encoder feedback signal are combined by the fully closed loop dual feedback filter in ([Pr. 67]) 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 "1000" is set as the filter value of [Pr. 67 Fully closed

loop dual feedback filter], fully closed loop control is always performed.

15. FULLY CLOSED LOOP SYSTEM

15 - 2

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.

To perform fully closed loop control, set [Pr. 62] besides operation mode selection.

When an incorrect value is set in "Encoder cable communication method selection" in [Pr. 23], [AL. 70] will occur at power on of the servo amplifier.

For models and specifications of the servo system controller capable of switching semi closed loop control/fully closed loop control, contact your local sales office.

(a) Operation mode switching

The following explains how to change the MR-J4-_B_-RJ020 mode to J2S compatibility and fully closed loop control mode. When you use an MR-J4-_B_-RJ020 servo amplifier in J2S compatibility and fully closed loop control mode, use the application software "MR-J4(W)-B mode selection" came with MR Configurator2 whose software version is A3 or later. The application software "MR-J4(W)-B mode selection" is designed for USB connection only.

1) Turn on the servo amplifier with MR-J4-T20 connected.

2) Start the application software "MR-J4(W)-B mode selection" and check that "J2S compatibility

mode" is displayed in the "Compatibility Mode". If not displayed, check (5) in this section to repeat the procedure.

3) After selecting "Change the mode", select "J2S compatibility mode".

Select "Fully closed loop control mode" for "Operation Mode".

15. FULLY CLOSED LOOP SYSTEM

(4) Setting of load-side encoder polarity

CAUTION

Do not set an incorrect direction to "Load-side encoder polarity" in [Pr. 62]. An abnormal operation and a machine collision may occur if an incorrect direction is set, which cause a fault and parts damaged. Also, it may cause [AL. 42] during the positioning operation.

POINT

Setting of load-side encoder polarity is irrelevant to [Pr. 7 Rotation direction selection]. Make sure to set it according to the relationships between servo motor and linear encoder or rotary encoder.

(5) Setting of load-side encoder electronic gear

POINT

When an incorrect value is set in the linear encoder electronic gear ([Pr. 65], [Pr. 66]), normal operation may not be performed. Also, it may cause [AL. 42] during the positioning operation.

To change setting value, set "000F" in [Pr. 40 Parameter writing inhibit]. Cycling the power will enable the setting value.

Set the numerator ([Pr. 65]) and denominator ([Pr. 66]) of the electronic gear to the servo motor-side encoder pulse. Set the electronic gear so that the number of servo motor encoder pulses per servo motor revolution is converted to the number of load-side encoder pulses. The relational expression is shown below.

(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 Configurator (MRZJW3-SETUP161E) may be used. Refer to section 15.3.9 for the data displayed on the MR Configurator.

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 pulse 2 (on load-side encoder) 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 within-full-one-revolution position (load-side encoder position within one-revolution) value 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 the feedback direction at the within-full-one-revolution position (load-side encoder position within one-revolution) by moving the device (load-side encoder) manually in a servo off state. When the servo motor and load-side encoder feedback directions match, rotating the servo motor in the CCW direction (counterclockwise as viewed from the shaft end) increases the position in load-side encoder 1-revolution, and rotating the servo motor in the CW direction (clockwise as viewed from the shaft end) decreases the position in load-side encoder 1- revolution. When the servo motor and load-side encoder directions do not match, operation is performed oppositely.

4 Fully closed loop electronic gear setting

When the servo motor and load-side encoders operate synchronously, the cumulative feedback pulse (on motor encoder) and cumulative feedback pulse 2 (on load-side encoder) values increase in accordance with the setting ratio of the fully closed loop electronic gear ([Pr. 65]/[Pr. 66]). Confirmation example When the servo motor is directly coupled with a ball screw and the linear encoder resolution is 1.0 m

Servo motor encoder resolution = 131072 pulses/rev Ball screw lead = 4.0 mm Linear encoder resolution = 1.0 m

When the movement is equivalent to one servo motor revolution (Load-side: 4.0 mm), cumulative feedback pulse 2 (on load-side encoder) = 4000 pulses.

With the initial value (setting = 10) set in [Pr. 67 Dual feedback filter], make gain adjustment by auto tuning, etc. as in semi closed loop control. While observing the servo operation waveform with the graph function, etc. of MR Configurator (MRZJW3-SETUP161E), adjust the dual feedback filter.

Increasing the dual feedback filter setting shortens the settling time, but increases servo motor vibration since the motor is more likely to be influenced by the load-side encoder vibration. The maximum setting of the dual feedback filter should be less than half of the PG2 ([Pr. 15]) setting.

15.3.2 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.

Compatible encoder types are omitted as follows. Serial interface: Mitsubishi Electric serial interface compatible encoder General pulse output: A/B/Z-phase differential output encoder Common to all load-side encoders: Load-side encoders compatible with this model (For details, refer to section 15.1.)

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

(a) About proximity dog type home position return using absolute type linear encoder When an absolute type linear encoder is used, the home position reference 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.

direction When an incremental linear encoder is used, the home position is the position per servo motor revolution to the linear encoder home position (reference mark) passed through first after a home position return start. In the case of a proximity dog type home position return, the nearest position after proximity dog off is the home position. Set one linear encoder home position in the full stroke, and set it in the position that can always be passed through after a home position return start.

2) When the linear encoder home position does not exist in the home position return direction

POINT

To execute a home position return securely, start a home position return after moving the axis to the opposite stroke end by jog operation, etc. of the controller.

A home position return cannot be made if the incremental linear encoder does not have a linear encoder home position (reference mark). Always provide a linear encoder home position (reference mark). (one place in the fully stroke)

If the home position return is performed from the position where the linear encoder home position (reference mark) does not exist, a home position return error occurs on the controller side. The error contents differ according to the controller type. When starting a home position return at the position where the linear encoder home position (reference mark) does not exist in the home position return direction, move the axis up to the stroke end on the side opposite to the home position return direction by JOG operation, etc. of the controller once, then make a home position return.

3) Instructions when the system uses the positioning module (QD75M) or VME bus Position Board

(MR-MC01) as a servo system controller.

POINT

The home position return retry function of the positioning module (QD75M) cannot be used.

The linear encoder home position (reference mark) has some width in the region where the signal turns on.

ON OFFHome position signal

Signal ON width (Note)

Note. The signal ON width changes depending on the used linear encoder. For details,

contact each linear encoder manufacturer.

The positioning module (QD75M) or VME bus Position Board (MR-MC01) determines the home position reference position when the linear encoder home position (reference mark) is passed through first after power-on of the servo amplifier. Therefore, a lag equivalent to the home position signal width is produced in the home position reference position depending on the direction in which the linear encoder home position (reference mark) is passed through.

When it is desired to always make a home position return to the same position without a lag equivalent to the home position signal width, a home position return must be performed so that the home position is always passed through in the same direction after power-on. The following indicates a home position return method in which a lag equivalent to the home position signal width is not produced in the positioning module (QD75M) or VME bus Position Board (MR-MC01).

a) Move it to the position where the stroke end signal on the side opposite to the home position

(b) About data setting type/count type 2 (Common to all load-side encoders)

In the data setting type/count type 2 (QD75M) home position return method, a home position return can be normally made if the home position has been passed through (in either direction) before start of a home position return, since a linear encoder home position (reference mark) or the Z-phase signal of a rotary encoder is not required. In the data setting type home position return method, pass through a home position (reference mark) and the Z-phase signal of the rotary encoder, and then make a home position return. When a linear encoder does not have a linear encoder home position (reference mark), or the machine has no distance of one servo motor encoder revolution until the Z-phase of the rotary encoder is passed through, a home position return can be made by changing "Home position setting condition selection" in [Pr. 33] if the home position is not yet passed through.

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 need not be installed to the servo amplifier. When a rotary encoder is used, an absolute position detection system can be configured by installing the encoder battery 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. (1) Operation from controller

Positioning operation from the controller is basically performed like the semi closed loop control. (2) Servo system controller setting

When using fully closed loop system, make the following setting. After values of [Pr. 23], [Pr. 33], [Pr. 62], [Pr. 65], [Pr. 66], and [Pr. 68] are written to the servo amplifier, cycling the servo amplifier power supply enables the settings.

(3) Additional instructions

The positioning module (QD75M) controls the servo parameters [Pr. 0] to [Pr. 75]. Therefore, when setting any of the servo parameters up to [Pr. 75], change the buffer memory setting of the positioning module in a sequence program. If the settings of the parameters [Pr. 0] to [Pr. 75] are changed using MR Configurator, they are not reflected on the positioning module.

15.3.4 Fully closed loop control error detection functions

POINT

The speed deviation error detection and position deviation error detection are both enabled for the initial setting.

The detection level setting can be changed using [Pr. 63] and [Pr. 64]. To change these setting values, set "000F" in [Pr. 40 Parameter writing inhibit]. [Pr. 62] setting will be enabled after the power is cycled

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 different detection methods, speed deviation and position deviation, and errors are detected only when the corresponding functions are enabled by setting "Fully closed loop control error detection function" (_ x _ _) in [Pr. 62 Fully closed loop selection].

15.3.8 Absolute position detection system under fully closed loop system

POINT

When configuring an absolute position detection system in the semi closed loop control, the encoder battery must be installed to the servo amplifier as in the case that the operation mode is in "standard control mode". Connect the encoder cable of the servo motor-side encoder directly to the servo amplifier.

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 need not be installed to the servo amplifier. When a rotary encoder is used, an absolute position detection system can be configured by installing the encoder battery 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. For the absolute position detection system with linear encoder, the restrictions mentioned in this section apply. Enable the absolute position detection system with "Absolute position detection system selection" (_ _ _ x) in [Pr. 1] and use this servo within the following restrictions. (1) Using conditions

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

(b) Select Always fully closed loop selection ([Pr. 62] = "_ _ _ 1"). (2) Absolute position detection range using encoder

38 *ENR Encoder output pulses Used to set the encoder pulses (A-phase and B-phase) output by the servo amplifier. Set the value 4 times greater than the A-phase and B-phase pulses. You can use [Pr. 33] to choose the output pulse setting or output division ratio setting. The number of A-phase and B-phase pulses actually output is 1/4 times greater than the preset number of pulses. The maximum output frequency is 1.3 Mpulses/s (after multiplication by 4). Use this parameter within this range. When the fully closed loop function is enabled in [Pr. 62] (FCT), and the A/B/Z-phase pulse output of the load-side encoder is selected in [Pr. 68] (FC2), consider it as "equivalent to one motor revolution" = "travel distance of the load-side encoder equivalent to one revolution of the semi closed-side motor". For example, when the linear encoder of 0.1 m resolution is installed as the load-side encoder to move 10 mm per servo motor revolution, 1. On the assumption that the parameter setting value is "20" for dividing ratio setting

The following caution is added to the packages of the target batteries. "Containing lithium metal battery. Regulations apply for transportation."

(5) Transportation precaution for customers

For sea or air transportation, attaching the handling label (figure) must be attached to the package of a Mitsubishi Electric cell or battery. In addition, attaching it to the outer package containing several packages of Mitsubishi Electric cells or batteries is also required. When the content of a package must be handled as dangerous goods (Class 9), the Shipper's Declaration for Dangerous Goods is required, and the package must be compliant with Class 9 Packages. Documentations like the handling label in the specified design and the Shipper's Declaration for Dangerous Goods are required for transportation. Please attach the documentations to the packages and the outer package.

The IATA Dangerous Goods Regulations are revised, and the requirements are changed annually. When customers transport lithium batteries by themselves, the responsibility for the cargo lies with the customers. Thus, be sure to check the latest version of the IATA Dangerous Goods Regulations.

App. 12 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. 5 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
