1. Usage

WARNING The MELIPM series motor is a synchronous motor with high-performance magnets built in its rotor. Therefore, after the drive unit is powered off, there are high voltages at the motor terminals while the motor is running. Before starting wiring or maintenance and inspection, make sure that the motor has stopped. In any application where the motor is rotated by a load such as a fan or blower, connect a low-voltage manual switch on the drive unit's output side, open the switch, and start wiring or maintenance and inspection. Not doing so can cause an electric shock. Never disassemble or modify the unit. Doing so can cause an electric shock, fire or injury. Do not use the unit with any load other than the specified motor. Doing so can cause a fire or injury. Provide safety devices for the whole system, e.g. emergency brakes, to ensure that the machine or device is not placed in hazardous conditions when the drive unit fails.

CAUTION If a holding brake is required, prepare it separately. The brake function of the drive unit cannot keep holding the load. Injury may result. Before operating the drive unit which had been stored for an extended period of time, perform inspection and test operation on the unit before using. Not doing so may cause accidents.

2. Transportation

CAUTION Do not stack the drive unit boxes higher than the number indicated on the package. Doing so can cause injury. Confirm the weight before carrying the drive unit. Not doing so can cause injury. When carrying the drive unit, do not exert a force partially, i.e. do not hold the front cover operation panel. Doing so can cause the unit to drop, leading to injury. The drive unit is precision piece of equipment. Do not drop it or subject it to impact, this may damage the drive unit.

3. Installation

CAUTION Do not install or operate the drive unit if it is damaged or has parts missing. Such installation or operation can cause accidents. Always install the drive unit in the specified orientation and environment. Not doing so can cause a fire or accidents. Install the drive unit on an incombustible material such as metal. Not doing so can cause a fire.

Do not place combustible materials nearby. Doing so can cause a fire. Install the drive unit in a load-bearing place. Not doing so can cause accidents. Prevent screws, metal pieces or other conductive foreign matter, or wood scrap, oil or other flammable foreign matter from entering the drive unit. They can cause a fire or accidents.

4. Wiring

WARNING Any person who is involved in the wiring of this equipment should be fully competent to do the work. Otherwise, an electric shock or fire can occur. Install a no-fuse breaker or earth leakage circuit breaker. Otherwise, a drive unit failure can cause large currents to flow, resulting in a fire. Always install the unit before wiring. Otherwise, an electric shock or fire can occur. Before restarting wiring after power-on, make sure that the motor is at a stop, wait for more than 10 minutes after switching power off, and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do the work. Immediately after power-off, the DC terminals P/+, N/- are charged with more than 200V (residual voltage of the internal capacitor). Therefore, an electric shock may occur.

Even after power-off, the motor connection terminals U, V, W have high voltages while the motor is running. Always start wiring after confirming that the motor has stopped. Not doing so can cause an electric shock. Earth the drive unit. Not doing so can cause an electric shock or fire.

CAUTION Make sure that the input power supply voltage matches the rated voltage specifications. Mismatch can cause a fire or accidents. Check the terminal layout and terminal symbols to ensure that connections are correct. Wrong connections can cause a fire or accidents.

Do not connect a power supply to the motor connection terminals U, V, W. Doing so can cause a fire or accidents.

Connect the motor connection terminals U, V, W to match the motor phase sequence. Wrong connections can cause accidents due to reverse rotation of the motor.

Do not connect a resistor across the DC terminals P/+-N/-. Doing so can cause a fire or accidents.

Take measures to prevent peripheral sensors and equipment from malfunctioning due to electromagnetic noises. Not doing so can cause accidents.

Take measures to prevent peripheral power capacitors and generators from overheating or being damaged due to power harmonics. Not doing so can cause a fire. Connect the power capacitor, surge suppressor and radio noise filter (FR-BIF option) on the power supply side. Connection on the output side can cause a fire.

5. Operation

WARNING Always replace the front cover before switching input power on. While power is on, do not remove the front cover. Doing so can cause an electric shock. Operate the switches with dry hands. Not doing so can cause an electric shock. Prepare an emergency stop switch separately. The "STOP/RESET" key of the operation panel or parameter unit is valid for stopping only when the function setting has been made. Not using a separate emergency stop switch can cause accidents.

When the stall prevention function is activated, operation will be performed independently of the preset acceleration/deceleration time and preset speed. Design the machine to ensure safety if the stall prevention function is activated. Not doing so can cause accidents.

Selecting the retry function will restart the drive unit suddenly when it is at an alarm stop. Design the machine to ensure personal safety if the drive unit is restarted. Not doing so can cause accidents. At the occurrence of an alarm, turn off the run signal before resetting the alarm. The drive unit will restart abruptly if you reset the alarm with the run signal on. It can cause injury. At occurrence of an alarm, turn off the run signal. If you do not turn off the run signal, the alarm may be reset due to power OFF-ON at occurrence of an instantaneous power failure or like, restarting the drive unit suddenly. It can cause injury.

CAUTION You can set the motor speed easily between low speed and high speed. Set the speed command which will not exceed the permissible range of machine design. Not doing so can cause accidents. If the motor is rotated by the load, ensure that the motor will not exceed its maximum speed. The drive unit may be damaged. While power is on or some time after power-off, do not touch the heat sink and brake resistor as they are hot. You may get burnt. The electronic overcurrent protection function for motor overheat protection is initialized when the drive unit is reset. Frequent resetting of the drive unit will disable motor overheat protection. The motor may be burnt if it is operated under overload.

6. Maintenance, Inspection and Part (Cooling Fan) Replacement

WARNING Any person who is involved in maintenance, inspection or part replacement should be fully competent to do the work. Otherwise, an electric shock or injury can occur. Before starting maintenance, inspection or part replacement, make sure that the motor is at a stop, wait for more than 10 minutes after switching power off, and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do the work. Immediately after power-off, the DC terminals P/+, N/- are charged with more than 200V (residual voltage of the internal capacitor). Therefore, an electric shock may occur.

Even after power-off, the motor connection terminals U, V, W have high voltages while the motor is running. Always start the work after confirming that the motor has stopped. Not doing so can cause an electric shock.

Do not conduct a pressure test. A pressure test can damage the drive unit. Do not perform an insulation resistance test on the control circuit using a megger. Such a test can damage the drive unit. While power is on, do not replace the cooling fan. Replacing the cooling fan during power- on can be hazardous.

7. Disposal

CAUTION Dispose of the drive unit as general industrial waste. Its solder (lead) can cause environmental contamination.

NOTICE

Choose the size of the wires connected to the motor connection terminals so that a voltage drop due to the wires is less than 4V. The minimum wire size in the above selection table assumes that the wiring length is less than 20m. A voltage drop can be found by the following expression: Line voltage drop (mV) = 3 wire resistance (/km) wiring length (m) current (A)

Use the ground cable which is as thick as possible.

We recommend you to use the 0.75mm2 or less wire size for the control circuit terminals. Using the wire size of 1.25mm2 or more may cause the front cover to bulge, leading to a contact fault in the operation panel or parameter unit, when there are many cables wired, for example.

2.3 Installation Method

1) Remove the front cover. 2) Pass screws or bolts into the four mounting holes and secure the drive unit. 3) Replace the removed cover. Leave the cover removed when continuing the wiring work.

CAUTION Prevent screws, metal pieces and other conductive foreign matter and oil and other flammable foreign matter from entering the drive unit. Securely screw or bolt the unit to the mounting surface vertically without looseness. Always install the unit in the specified mounting orientation. Not doing so can cause a failure.

Do not drop the unit, or subject it to impact.

NOTICE

Fully check that the front cover has been mounted securely. Insecure mounting can cause a drop due to vibration or a display fault of the operation panel.

This chapter describes the wiring of the drive unit.

WARNING Any person who is involved in the wiring of this equipment should be fully competent to do the work. Otherwise, an electric shock or fire can occur. Always install the unit before wiring. Otherwise, an electric shock or fire can occur. Before restarting wiring after switching power "ON", make sure that the motor is at a stop, wait for more than 10 minutes after switching power "OFF", and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do wiring. Immediately after power "OFF", the DC terminals P/+, N/- are charged with more than 200V (residual voltage of the internal capacitor). Therefore, an electric shock may occur. Even after power-off, the motor connection terminals U, V, W have high voltages while the motor is running. Always start wiring after confirming that the motor has stopped. Not doing so can cause an electric shock.

CAUTION Take measures to prevent peripheral sensors and equipment from malfunctioning due to electromagnetic noises. Not doing so can cause accidents. Take measures to prevent peripheral power capacitors and generators from overheating or being damaged due to power harmonics. Not doing so can cause a fire. Do not leave wire offcuts in the drive unit. Doing so can cause a fault, failure or malfunction. If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor on the power supply side and also make up a sequence which will not turn "ON" the start signal automatically when power is restored. Tighten the terminal screws to the specified torque. Undertightening can cause an inter-terminal short circuit or malfunction. Overtightening can cause the screws and unit to be damaged, resulting in a short circuit, malfunction or the like. When using the unit having a built-in brake resistor or using the brake resistor (option), switch power off with the alarm signal of the unit. If you do not so, a brake transistor failure or like may overheat the brake resistor abnormally, causing a fire.

3.1.2 Noises

Take the following measures if you want to further suppress noises which affect the drive unit or when there are devices nearby which are susceptible to noises (e.g. measuring instruments, telephone lines, various sensors).

(1) When noises are expected from the drive unit signal cables Fit data line filters to the signal cables.

(2) When there are devices nearby which are connected to the power supply whose line is different from that of the drive unit

Run the signal cables of the device as far away as possible from the drive unit and its power cable.

Avoid the parallel wiring and bundling of the device's signal cables and the drive unit's power cable.

Connect a line noise filter to the input or output side of the drive unit's power cable.

Connect a radio noise filter to the input side of the drive unit's power cable.

Use shielded cables as the signal and power cables.

Run the signal and power cables in separate metal conduits.

(3) When there are devices which are connected to the power supply whose line is the same as that of the drive unit

Connect a line noise filter to the input or output side of the drive unit's power cable.

Connect a radio noise filter to the input side of the drive unit's power cable.

NOTICE

The effects of the above noise suppression techniques depend on the propagation paths of noises and the noise immunities of the devices.

3.3.3 Switching between sink logic and source logic

Description

Sink Logic Source Logic

In this logic, a signal turns ON when a current flows out of the input terminal.

In this logic, a signal turns ON when a current flows into the input terminal.

To use the contact input terminals as source logic, the connector on the back of the control circuit terminal block must be moved to the other position. The control logic is factory-set to sink logic.

MEMO You need not change the connector position when using only the transistor output terminals as source logic.

To use the terminals as source logic, change the setting in the following procedure.

1) Loosen the two mounting screws on both ends of the control circuit terminal block. (The screws cannot be removed.)

2) With both hands, pull down the terminal block from the back of the control circuit terminals.

Loosen. Loosen.

3) Change the connector position on the back of the terminal block from "SINK" to "SOURCE".

4) Reinstall the control circuit terminal block in the original position and fix it with the screws.

NOTICE

While power is on, never disconnect the control circuit terminal block. Check the control circuit connector CON1 to ensure that the pins are fitted properly without bending. Make sure that the logic changing connector is inserted correctly. The logic changing connector is a small component. Handle it with care when changing the logic. The logic changing connector must be fitted in only one of the above positions. Fitting it in both positions at the same time can cause a failure.

5.1 Power On

Switch power on after making sure that the unit has been installed and wired properly and that the start signal is OFF. The LEDs and POWER lamp of the operation panel are lit.

NOTICE

If the LEDs do not come on, check the following: There is no contact fault in the connection of the operation panel and the drive unit; The jumper across the DC reactor connection terminals P/+-P1 is fitted properly; and The jumper across the control circuit power supply terminals R1-S1 is fitted properly.

5.2 Parameter Setting

5.2.1 Setting of the operation mode parameter

Depending on the start signal (forward rotation command, reverse rotation command, stop command) and speed setting signal input method, you may need to set the parameter. Choose the used operation mode in Pr. 79 [Section 8.2].

5.2.2 Confirmation of the basic operation parameters

To meet various applications, a wealth of parameter functions are available for the drive unit. The drive unit is designed to perform simple variable-speed operation using the parameter values set before shipment from the factory. Depending on the specification conditions of the load (machine), however, some parameter values may need to be checked and changed. The parameters marked BASIC in the table of contents of Chapter 8 PARAMETER FUNCTIONS are the basic operation parameters whose values are recommended to be checked prior to operation. Set them to values which match the specification conditions of the load.

You may turn the start signal on/off to start operation after entering the speed setting signal. In this case, the motor speed rises or falls in accordance with the preset acceleration/deceleration time.

Use Pr. 902 to 905 [Section 8.3.1] to change the relationship between the analog speed command and motor speed.

When the start signal is entered after the input of the speed command, the motor starts running approx. 0.1s after the input of the start signal.

When the analog signal is used to give the speed command, the motor starts running approx. 0.1s after the speed command has reached the value equivalent to 100r/min (value set in Pr. 13).

For forward/reverse rotation operation, there is an about 0.1s to 3.0s stop depending on the operating conditions.

NOTICE

When restarting the motor after decelerating it to a stop, start the motor after ensuring that it has stopped. If you start the motor that has not yet come to a complete stop, sufficient torque may not be provided. Especially when the load torque (friction torque) is small and the load inertia moment is large, the motor will run slightly even after the voltage braking operation has stopped. Therefore, restart the motor after making sure that it has stopped completely.

6.4.2 Wear parts

The replacement lives of the parts are as indicated below. Since the lives vary with the operating environment and/or usage, you must replace the parts if you have found any fault during periodic inspection or the like.

Part Name Standard

Replacement Intervals

Method Remarks

Cooling fan 2 to 3 years Change (as required)

The bearing life of the cooling fan is 10,000 to 35,000 hours. For continuous operation, therefore, normally replace the fan every 2 to 3 years as a guideline.

Main circuit smoothing capacitor

10 years Change (as required)

On-board smoothing capacitor

10 years Change (as required)

The life greatly depends on the ambient temperature and operation specifications of the drive unit. When continuous operation is performed in normal air-conditioned environment, the life is approximately 10 years. The life halves for each 10C rise in ambient temperature. The capacitor deteriorates rapidly after the given period has elapsed, causing the motor to run unstably or activating the overcurrent protective function.

Note 1. When the carrier frequency exceeds 5kHz (Pr. 72 = 3 [Section 8.5.7]), do not use the instrument because eddy current losses occurring in the metallic parts inside the instrument will increase and may lead to burnout. In this case, use an approximate effective value type instrument.

2. Use an FFT to measure the output voltage accurately. Accurate measurement cannot be made if you use a tester or general measuring instrument.

6. TROUBLESHOOTING

(2) Measurement of power factor The power factor cannot be measured with a commercially available power-factor meter which is designed to measure the phase difference between a voltage and a current. Measure the power supply side voltage, current and power, then calculate the power factor using the following expression. Calculate the power factor of the motor alone from the output side voltage, current and power.

This chapter describes the parameter functions of the drive unit. The parameters are basically explained in the following format.

Example: Pr. 10, 11

Pr. 10 100

Pr. 11 9999"voltage braking operation time"

Parameter number Parameter description Factory setting Initial value

"voltage braking operation speed"

Pr. Setting Range Unit Operation

10 0 to 200 r/min At the preset speed or less, the motor is stopped by voltage braking.

0.0 to 60.0 s Set the voltage braking time. Setting 0 coasts the motor to a stop at the Pr. 10 setting or less.11

9999 The voltage braking time (0 to 3s) is adjusted automatically.

The minimum increment of the setting is 0.1 in the setting range 0.0 to 60.0, or 1 in the range 0 to 60.

The value having a 0 on the right of the decimal point can be entered as an integer. (Example: 10.0 10)

MEMO

If any parameter cannot be set, check that: The start signal (STF or STR) is not "ON". The parameter write disable selection (Pr. 77) setting has not been made. The PU operation mode has not been selected. When the PU operation mode cannot be selected, check that: The start signal (STF or STR) is not "ON".

In response to the selection of the PU operation mode or external operation mode from the operation panel or parameter unit (FR-PU04), the operation command right can be changed from the external operation to the PU operation or from the PU operation to the external operation without stopping the operation.

The operation in the switch-over mode is performed as described in the following table.

Operation Mode Switching Switching Control/Operation Status

External operation PU operation

The operation mode is switched to the PU operation mode. The rotation direction remains unchanged from the direction

of the external operation. The speed remains unchanged from the setting of the

external operation. (Once power is switched "OFF" or a reset is made, the stored setting of the external operation is cleared to "0" and the operation stops.)

PU operation external operation

The operation mode is switched to the external operation mode. The rotation direction is determined by the input signal of the

external operation. The speed is determined by the external setting signal.

Setting Mode Function

7 PU operation interlock

When the contact input terminal for the X12 signal has been selected is "OFF", the operation mode is fixed to the external operation mode. To switch it to the PU operation mode, turn "ON" the X12 signal and change the operation mode from the operation panel. Turning the X12 signal "OFF" automatically returns the operation mode to the external operation mode. When the X12 signal is not selected, the MRS terminal acts as the terminal having the function of the X12 signal.

8 External signal switching

When the contact input terminal where the X16 signal has been selected is "ON", the operation mode is fixed to the external operation mode, or when that terminal is "OFF", the operation mode is fixed to the PU operation mode. Switching is enabled during a stop only.

Refer to: 8.4 Selection of the Control Circuit Contact Input Terminal Functions

MEMO

If the X12 signal is "ON" in the PU operation interlock mode, the operation mode cannot be changed to PU operation when the start signal (STF, STR) is "ON". Switching to external operation is independent of "ON"/"OFF" of the start signal. When the X12 signal is turned "OFF" with the start signal "ON", operation is performed in accordance with the external operation command. When the MRS terminal is used as the X12 signal, the signal logic change set in Pr. 17 [Section 8.4] is valid. When using the unit in the communication operation mode from the PU connector, change the operation mode through communication. You need not set Pr. 79.

Initial value

Pr. 59 "remote setting function selection" 0

You can perform operation by changing the speed continuously with only the contact signals without using the analog speed signal.

FunctionSetting Remote setting function Speed setting storage function 0 No 1 Yes Yes 2 Yes No

When "Yes" is selected for the remote setting function, the terminals assigned to the RH, RM and RL signals in Pr. 180 to 187 "8.4 Selection of the Control Circuit Input Terminal Functions" provide the acceleration, deceleration and clear functions.

While the RH signal is "ON", the speed increases according to the preset acceleration time. While the RM signal is "ON", the speed decreases according to the preset deceleration time.

When "Yes" is selected for the speed setting storage function, the running speed at the time when the start signal (STF or STR) is turned "OFF" is stored. If the start signal is not turned "OFF", the running speed more than 1 minute after the RH or RM signal is turned "OFF" is stored.

When the running speed has been stored, merely switching power on again and inputting the start signal starts operation at the stored running speed.

Turning "ON" the RL signal clears the stored speed and decelerates the motor to a stop. Controlling the RH/RM signal with the start signal "OFF" varies the preset speed. When the acceleration or deceleration signal turns ON, the preset speed varies according to the

slope set in Pr. 44 or 45 [Section 8.5.2]. The acceleration/deceleration times of the output speed are as set in Pr. 7 and 8 [Section 8.5.2]. Therefore, the actual output speed varies at the longer preset times.

The speed can be added to the preset speed other than the multi-speed.

MEMO

The minimum value of acceleration/deceleration time is 0.08s. Any acceleration/deceleration time setting of less than 0.08 is handled as 0.08s. The upper limit of acceleration time at up to 100r/min is 5s (converted at reference speed 2000r/min). When the acceleration time setting is greater than 5s, therefore, the acceleration time required to reach the acceleration/deceleration reference speed is represented by the following expression and is shorter than the preset acceleration time:

Required acceleration time = 0.25 + T1 T1 = (preset speed command - 100) Pr. 7 setting/Pr. 20 setting

The value less than the Pr. 10 setting will voltage-brake or coast the motor to a stop. Therefore, the deceleration time required to decrease the speed from the speed set in Pr. 20 to the speed set in Pr. 10 is as follows:

Required deceleration time = Pr. 8 setting (Pr. 20 setting - Pr. 10 setting)/ Pr. 20 setting

A too short acceleration/deceleration time setting can cause an abnormal stop due to overload, overcurrent or overvoltage. Make a setting which will not display overload on the operation panel. Rapid acceleration of less than 0.2s may make the starting torque insufficient.

NOTICE

Communication operation is performed in response to the communication request from the personal computer. Therefore, if communication is suspended due to a communication cable break or computer failure during operation, the drive unit cannot detect a fault and stop operation. However, operation is brought to an alarm stop (E. PUE) if the time set as the communication check time interval has elapsed. To stop operation before the time set as the communication check time interval is reached, reset the CPU using the RES terminal or switch power off. The motor will then coast to a stop.

5) Error codes When the data received by the drive unit is in error, the error code is returned to the computer. The definitions of the error codes are as follows.

Error Code Error Item Error Definition Drive Unit Operation

H0 Computer NAK error

The number of errors consecutively detected in communication request data from the computer is greater than the permissible number of retries.

H1 Parity error The parity check result does not match the specified parity.

H2 Sumcheck error

The sumcheck value in the computer does not match that of the data received by the drive unit.

H3 Protocol error

Data received by the drive unit is in the wrong protocol, data receive is not completed within the given time, or CR and LF are not as set in the parameter.

H4 Framing error The stop bit length differs from the initial setting.

H5 Overrun

New data has been sent by the computer before the drive unit completes receiving the preceding data.

If errors occur consecutively more than the permissible number of communication retries (Pr. 121 setting), the drive unit displays E. PUE and comes to an alarm stop.

H7 Character error

The character received is invalid (other than 0 to 9, A to F, control code).

HA Mode error

Parameter write was attempted in other than the computer link operation mode or during drive unit operation, for example.

HB Instruction code error

The specified command does not exist.

HC Data range error

Invalid data has been specified for parameter write, running speed write, etc.

The receive data is made invalid and the drive unit continues operation.

NOTICE

The drive unit does not accept data from the computer if it is in error. Hence, always insert a data error retry program in the user program. Since the communication of any data, e.g. run command, monitor, is started from the computer, the drive unit will not return data without the computer's command. For monitoring, therefore, design the program to cause the computer to provide a data read request as required.

(6) Setting example

A detector which outputs the process values of 4mA at 0C and 20mA at 50C is used to adjust the temperature to 25C under PID control.

Procedure Description

Determine the set point.

Determine the set point of the item to be adjusted.

Set Pr. 128.

Convert the set point into

%.

Calculate the ratio of the set point to the detector output.

When the detector used has the specifications that 0C is equivalent to 4mA and 50C to 20mA, the set point 25C is 50% because 4mA is equivalent to 0% and 20mA to 100%.

Calibrate the signals.

Calibrate the set point input and detector output as required.

Make calibration using Pr. 902 to 905 [Section 8.3.1].

Set the set point.

Enter a voltage into terminal 2 according to the set point (%).

When the selected feature of the terminal 2 is 0 to 5V, 0V corresponds to 0% and 5V to 100%. Therefore, enter 2.5V which corresponds to 50%. When entering the set point from the operation panel, set "50" in Pr. 133.

Operation Turn "ON" the start signal and check that the process value is stable.

Set the proportional band, Pr. 129, slightly larger, the integral time, Pr. 130, slightly longer, and the differential time, Pr. 134, slightly shorter, and start operation.

Adjustment Stabilize the operating status (detector output).

When stable Reduce the proportional band, decrease the integral time, and increase the differential time to increase the response performance. When instable Increase the proportional band, increase the integral time, and decrease the differential time.

0 to 3000 r/min

When the motor speed at power "OFF" is greater than the value set in Pr. 263, deceleration starts at the value found by subtracting the Pr. 262 setting from the motor speed. When the motor speed is less than the Pr. 263 setting, the motor is decelerated to a stop, starting at the motor speed. When the Pr. 263 setting and motor speed are close, the Pr. 262 function may not be activated.

9999 The deceleration slope from the Pr. 266 setting to a stop is the value set in Pr. 264.

266 0 to 3000 r/min Set the speed at which the deceleration slope is changed.

MEMO

Depending on the load, the power-failure detection function may not be activated properly, causing the motor to coast to a stop. If the motor speed at power "OFF" is less than the Pr. 262 setting, the motor stops immediately. If power is switched on during power-failure deceleration operation, deceleration-to- stop operation is continued. To restart, turn "OFF" the start signal once, then turn it "ON" again. When the FR-HC high power factor converter is used, this function is made invalid.
