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 wiring or inspection, the motor must be confirmed to be 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. Safety devices must be provided for the whole system, e.g. emergency
brakes, to ensure that the machine or device is not placed in hazardous conditions if the drive unit fails.
CAUTION If a holding brake is required, it must be prepared separately. Stop status
cannot be held by the inverter's brake function. This may result in injury. Before operating the drive unit which had been stored for an extended
period of time, inspection and test operations must be performed on the unit before using. Not doing so can cause accidents.
2. Transportation
CAUTION Do not stack the drive unit boxes higher than the number indicated on the
package. Injury may result. The weight must be confirmed 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 or operation panel. Doing so can cause the unit to drop, leading to injury.
The drive unit is precision piece of equipment. Do not drop the unit, or subject it to impact. Doing so can 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.
The drive unit must be always installed in the specified orientation and environment. Otherwise, they can cause a fire or accidents.
The drive unit must be installed on an inflammable material such as metal. Not doing so can cause a fire.
Do not place combustible materials nearby. Doing so can cause a fire. The drive unit must be installed to the position where it can withstand the
weight of the drive unit. Failure to do so can cause accidents. Foreign conductive objects must be prevented from entering the drive unit.
That includes screws and metal fragments or other flammable substance such as oil. 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 electric shock or fire may occur. A moulded case circuit breaker or earth leakage circuit breaker must be
installed. Otherwise, a drive unit failure can cause large currents to flow, resulting in a fire.
The unit must be installed before wiring. Not doing so can cause an electric shock or fire.
Before restarting wiring after power-on, the motor must be confirmed to be stopped, and 10 minutes or longer time must be elapsed after switching power off. Wiring must be performed after confirming 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). It may cause an electric shock.
Even after power-off, the motor connection terminals U, V, W have high voltages while the motor is running. The work must be started after confirming that the motor has stopped. Not doing so can cause an electric shock.
This drive unit must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). Not doing so can cause an electric shock or fire.
5
CAUTION
The input power supply voltage must match the rated voltage specifications. Mismatch can cause a fire or accidents.
The terminal layout and terminal symbols must be checked 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.
The motor connection terminals U, V, W must 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.
Measures must be taken to prevent peripheral power capacitors and generators from overheating or being damaged due to power harmonics. Not doing so can cause a fire.
The power factor correction capacitor, surge suppressor, and radio noise filter (FR-BIF option) must be connected on the power supply side. Connection on the output side can cause a fire.
5. Operation
WARNING The front cover must be reinstalled before switching input power on. While
power is on, do not remove the front cover. Doing so can cause an electric shock.
Do not touch the switches with wet hands. Doing so can cause an electric shock.
A separate switch that makes an emergency stop must be provided. The "STOP/RESET" key of the operation panel or parameter unit is valid for stopping only when the function setting has been made. Not providing a separate emergency switch may cause accidents.
When the stall prevention function is activated, operation will be performed independently of the preset acceleration/deceleration time and preset speed. The machine must be designed to ensure safety if the stall prevention function is activated. Not doing so can cause accidents.
At the occurrence of an alarm, the run signal must be turned off before resetting the alarm. The drive unit will restart abruptly if you reset the alarm with the run signal on. This may result in injury.
At occurrence of an alarm, the run signal must be turned off. If you do not turn off the run signal, the alarm may be reset due to power OFF-ON at the occurrence of an instantaneous power failure or like, restarting the drive unit suddenly. This may result in injury.
6
CAUTION
You can set the motor speed easily between low speed and high speed. The speed command must be set so that the machine speed will not exceed the permissible range of the machine design. Failure to do so can cause accidents.
If the motor is rotated by the load, the motor must be ensured not to exceed its maximum speed. Otherwise the drive unit may break.
While power is on or some time after power-off, do not touch the heatsink and brake resistor as they are hot. You may get burned.
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 burned 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.
The motor must be confirmed to be stopped and 10 minutes or longer time must be elapsed after switching power off. Replacement must be performed after confirming 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). Not doing so can cause an electric shock.
Even after power-off, the motor connection terminals U, V, W have high voltages while the motor is running. Always start replacement 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. A pressure 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

3. WIRING This section 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. Not doing so can cause an electric shock or fire.
Always install the unit before wiring. Not doing so can cause an electric shock or fire.
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 the work 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 factor improving 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.

should be 0.9mm maximum. If they are larger, the threads may be damaged during tightening.
3) Loosen the terminal screw and insert the cable into the terminal. 4) Tighten the screw to the specified torque.
Undertightening can cause cable disconnection or misoperation. Overtightening can cause damage to the screw or unit, leading to short circuit or misoperation. Tightening torque: 0.25Nm to 0.49Nm * Use a screwdriver No. 0 to tighten.
Note: When routing the stripped cables, twist them so that they do not become loose. In addition, do not solder it. Soldering can cause poor contact.
NOTICE
When using a blade terminal or a solid wire for wiring, use one of 0.9mm or less diameter. Using one of larger diameter may damage the threads during tightening.

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 starting torque may not be provided. Especially with small load torque (friction torque) and large load moment of inertia, the motor rotates slightly even after the voltage brake operation is completed. Make sure the motor is completely stopped before restarting the operation.
Refer to: Section 8.5.3 Stop operation Do not switch off the AC input power while the motor is running at
a high speed. Doing so may activate the undervoltage protective circuit instantaneously under the influence of a motor-generated voltage.

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
5 years Change (as required)
On-board smoothing capacitor
5 years Change (as required)
The life greatly depends on the surrounding air temperature and operation specifications of the drive unit. When continuous operation is performed in normal air-conditioned environment, the life is approximately 5 years. The life halves for each 10C rise in surrounding air temperature. The capacitor deteriorates rapidly after the given period has elapsed, causing the motor to run unstably or activating the overcurrent protective function.

6.4.3 Cooling fan replacement method Removal
1) Remove the wiring cover. 2) Unplug the fan connector.
The cooling fan is connected with the cooling fan connector on the drive unit terminal block side. Unplug the connector and remove the drive unit and cooling fan.
3) Remove the cooling fan cover. Push the cover in the direction of arrows and pull it down.
4) Remove the cooling fan and cooling fan cover. The cooling fan is secured by latches. The cooling fan and cooling fan cover can be removed by disengaging the latches.
Reinstallation
1) After confirming the orientation of the fan, reinstall the fan to the cover so that the arrow on the left of "AIR FLOW" faces in the opposite direction of the fan cover. Note: The wrong direction of air flow can shorten the drive unit life.
2) Reinstall the fan cover to the drive unit. Pass the wiring through the wiring groove to avoid it from being caught between the chassis and cover.
3) Connect the wiring to the connector. 4) Reinstall the wiring cover.

Pr. Setting Range Unit Operation
10 0 to 200 r/min Voltage braking is applied to stop the motor when the speed drops to the set speed or lower.
0.0 to 60.0 s Set the voltage braking time. While "0" is set, the motor coasts to stop when the speed drops to the Pr.10 setting or lower. 11
9999 Voltage braking time (0 to 3s) is automatically adjusted.
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". The operation mode (Pr.79) is set to a value other than "0."

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 with 2000r/min as the reference speed). 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 motor stops by voltage braking or by coasting when the speed falls to a speed lower than the Pr.10 setting. The required deceleration time from the speed set in Pr.20 to the speed set in Pr.10 can be calculated with: Required deceleration time = Pr. 8 setting (Pr. 20 setting -Pr. 10 setting)/Pr. 20 setting.
Too short of an 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.
Sudden acceleration in a time period less than 0.2s may cause starting torque shortage.

8.5.5 Stall prevention operation level Initial Value Pr. 22 "stall prevention operation level" 150
Setting Range Unit Remarks 0,150 % When 0 is set, the stall prevention function is not activated.
When the output current reaches the Pr. 22 setting, the speed is varied with the running status to suppress the torque. The setting is based on the rated motor current. When the stall prevention function is activated, OL appears on the screen of the operation panel or FR-PU04 parameter unit. That the stall prevention function has been activated can be exported as OL signal from the terminal.
Refer to: Section 8.7.2 Selection of the control circuit output terminal functions
MEMO
If the stall prevention function is activated during acceleration or deceleration, the acceleration or deceleration time [Section 8.5.2] will be longer than the setting. When the travel of a machine or the like is determined by the acceleration or deceleration time, the travel will increase due to the operation of the stall prevention function.
If the stall prevention function is activated during constant speed operation, the running speed may vary abruptly.

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 trips (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.

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.

Pr. Setting Range Unit Signal 42 0 to 3000 r/min FU
0 to 3000 r/min FU 43 9999 Once the motor speed has reached or exceeded the speed set in the corresponding parameter, it is exported from the control circuit output terminals where the FU signal has been assigned. Pr. 43 is valid for only the operation performed using the reverse rotation signal (terminal STR or REV key). Setting the Pr. 43 value makes the Pr. 42 setting invalid for reverse rotation signal operation so that you can separate detection between forward rotation operation and reverse rotation operation. Setting "9999" in Pr. 43 provides the same function as set in Pr. 42
