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 ter mi nals while the motor is running. Before
starting wiring or maintenance and inspection, make sure that the motor has
stopped. In any application wh er e the motor is rotated by a load su ch as a
fan or blower, connect a low -voltage manual switch on the drive unit' s output
side, open the switch, and start w iring or maintenance and inspe ction. Not
doing so can cause an electric shock.
Never disassem ble or modify the unit. Doing so can cause an electric shock,
fire or injury.
Do not use the unit with any load other than th e 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 c onditions
when the drive unit fails.
CAUTION
If a holding brake is required, prepare it separately. 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 cau s e accidents.
2. Transportation
CAUTION

4. Wiring
WARNING
Any person who is involv ed in the wiring of this equipment should b e fully
competent to do the work. Otherwise, an electric shock or fire can occur.
Install a no-fuse breaker or earth leakage circuit breake r. Othe rwise, a drive
unit failure can cause large currents to flow, resulting in a fire.
Always install the unit before wiring. Otherw is e, an electric shock or fire can
occur.
Before restarting wiring after pow er-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 enou gh to do the
work. Immediately after power-off, the DC terminals P/+, N/- are charged
with more than 200V (residual voltage of th e inter nal 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. Alw ays 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 o r fire.
CAUTION
Make sure that the input power supply voltage matches the rated voltage
specifications. Mismatc h c an cause a fire or accidents.
Check the terminal layout and ter minal symbols to ensure that connection s
are correct. Wrong connection s can cause a fire or accidents.
Do not connect a power supply to the motor connection ter minals U, V, W.
Doing so can caus e a fire or accidents.
Connect the motor connection terminals U, V, W to match the motor phase
sequence. Wrong connections can cause a ccidents 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 d oing so can
cause a fire.
Connect the power capacitor, surge suppressor an d r adio 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 befo re switching input power on. While power
is on, do not remove the front cover. D oing 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 parameter unit is valid for stop ping only when the function setting has
been made. Not using a se parate 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 ensu re safety if the stall prevention function is
activated. Not doing so can c ause 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 sig nal. If you do not turn off the
run signal, the alarm may be reset due to power OFF-ON at occur rence of
an instantaneous pow er 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 oc cur.
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 d rive unit.
While power is on, do not replace the cooling fan. Replacing the cooling fan
during power-on c an be hazardous.

2. INSTALLATION
2.3 Installation Method
1) Remove the front covers. (Up per and lower)
2) Remove the wiring cover.
3) Pass screws or bolts into the four mountin g holes and secure the drive unit.
(Three mounting holes for 0.75K or les s)
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 m ounting 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.
4) Replace the removed cover. Leave the cover re moved when continuing the
wiring work.
Fully check that the front cover has been mounted securely.
Insecure mounting can cause a drop due to vibration.
The front cover (Lower) is fitted wi th the c apacity plate and the drive

unit with the name plate. The same serial number is printed on
these plates. Always reinstall the c over to the drive unit from where
it had been removed.

3. WIRING
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 wirin g. 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 hav e high
voltages while the motor is running. Always start wiring after
confirming that the mo tor has stopped. Not doing so can cause an
electric shock.
CAUTION
Take measures to prevent peripheral sensors and equipm ent from
malfunctioning due to electromagne tic noises. Not doing so can cause
accidents.
Take measures to prevent peripheral power capacitors and generators
from overheating or being damaged du e 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.

*This resistor is not needed when you use the
parameter unit (FR-PU04) to make calibration. This
resistor is used when you need to calibrate the meter
nearby because the meter is at a remote location, for
example. Note that when you connect the calibration
resistor, the meter may not deflect to the full scale. In
this case, use the parameter unit with the resistor to
make calibration .
