result in electric shock.
yThe terminals on the driver’s front panel marked with symbol indicate the
presence of high voltage. Do not touch these terminals while the power is on. Doing
so may result in re or electric shock.
yWhen an alarm is generated in the driver (any of the driver's protective functions
is triggered), the motor stops and loses its holding torque. Accordingly, provide
measures to hold the moving part in a specic position in the event of an alarm.
Failure to do so may result in injury or damage to equipment.
yWhen an alarm is generated in the driver (any of the driver's protective functions
is triggered), remove the cause before clearing the alarm (protective function).
Continuing the operation without removing the cause of the problem may cause
malfunction of the motor and driver, leading to injury or damage to equipment.
Installation
yThe driver is Class I equipment. When installing the driver, install it inside an enclosure
so that it is out of the direct reach of users. Be sure to ground if users can touch it.
Failure to do so may result in electric shock.

supply. Failure to do so may result in re, electric shock, or injury.
yUse only an insulated screwdriver to adjust the driver’s switches. Failure to do so may
result in electric shock.
Maintenance and inspection
yDo not touch the terminals while conducting the insulation resistance measurement
or dielectric strength test. Doing so may result in electric shock.
Precautions for use
This chapter covers restrictions and requirements the user should consider when using
the product.
•Be sure to use our cable to connect the motor and driver.
Check the USER MANUAL for the cable models.
•When conducting the insulation resistance measurement or the
dielectric strength test, be sure to separate the connection between the
motor and the driver.
Conducting the insulation resistance measurement or dielectric strength test with the
motor and driver connected may result in damage to the product.
•Motor excitation at power ON
Simply turning on the power will not excite the motor. To excite the motor, always turn
the C-ON input ON. It is possible to set the motor to be excited automatically after the
power has been turned on, by changing the applicable driver parameter using the
support software MEXE02 or our data setter OPX-2A.
•Preventing electrical noise
Refer to the USER MANUAL for measures with regard to noise.
•Preventing leakage current
Stray capacitance exists between the driver’s current-carrying line and other current-
carrying lines, the earth and the motor, respectively. A high-frequency current may
leak out through such capacitance, having a detrimental eect on the surrounding
equipment. The actual leakage current depends on the driver’s switching frequency, the
length of wiring between the driver and motor, and so on. When providing a leakage
current breaker, use the following products, for example, which have high-frequency
signal protection:
Mitsubishi Electric Corporation: NV series
•Saving data to the non-volatile memory
Do not turn o the main power supply or 24 VDC power supply while writing the data to
the non-volatile memory and also do not turn o for 5 seconds after the completion of
writing the data. Doing so may abort the writing the data and cause an alarm of EEPROM
error to generate. The non-volatile memory can be rewritten approximately 100,000
times.
•When an alarm of overvoltage protection is generated
If vertical drive (gravitational operation) such as elevator applications is performed or if
sudden start-stop operation of a large inertial load is repeated frequently, an alarm of
overvoltage protection may be detected. If an overvoltage protection alarm is detected,
adjust the driving condition or use our regeneration resistor RGB100.
Notes when the connection cable is used
Note the following points when our cable is used.
•When inserting the connector
Hold the connector main body, and insert it
in straight securely. Inserting the connector
in an inclined state may result in damage to
terminals or a connection failure.
•When pulling out the connector
Pull out the connector in straight while releasing the lock part of the connector. Pulling
out the connector with holding the cable may result in damage to the connector.
•Bending radius of cable
Use the cable in a state where the bending
radius of the cable is more than six times of
the cable diameter.
Do not bend the lead wires part or x it
with a clamp. Doing so may cause damage
to the connector. More than 6 times
of cable diameter
Do not bend the lead wires part
•How to x the cable
Fix the cable near the connector so that stress is not applied to the connector part.
Use a wide clamp or x the connector at two places to prevent stress from being applied
to the connector.
In the case of a exible cable,
this area is a movable range.

* If the distance between the motor and driver is extended to 20 to 30 m (65.6 to
98.4 ft.), use a power supply of 24 VDC±4 %.
Once a 24 VDC power supply is connected, you can check the contents of alarms that
have generated even when the main power is cut o.
If a motor with electromagnetic brake is used, be sure to connect a 24 VDC power supply
as a power supply for the electromagnetic brake.
Since the 24 VDC power supply is not used for operating the motor, connect it as
necessary.
When turning on the 24 VDC power supply again, turn o the 24 VDC power
supply and wait for at least 1 second before doing so.
zConnecting the regeneration resistor
If vertical drive (gravitational operation) such as elevator applications is performed or if
sudden start-stop operation of a large inertial load is repeated frequently, connect our
regeneration resistor RGB100.
