yWhen an alarm is generated in the driver (any of the driver's protective
functions is triggered), take measures to hold the moving part in a specic
position since the motor stops and loses its holding torque. 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.
yInstall the driver inside an enclosure. Failure to do so may result in electric
shock or injury.
Connection
yAlways keep the power supply voltage of the driver within the specied
range. Failure to do so may result in re or electric shock.
yConnect the cables securely according to the wiring diagram. Failure to do
so may result in re or electric shock.
yDo not forcibly bend, pull, or pinch the cable. Doing so may result in re or
electric shock.
Operation
yTurn o the driver power supply in the event of a power failure. Otherwise,
the motor may suddenly start when the power is restored, causing injury or
damage to equipment.
yDo not remove the motor excitation during operation. Doing so may cause
the motor to stop and lose the holding force, resulting in injury or damage
to equipment.
Maintenance and inspection
yDo not touch the connection terminal of the driver while the power is
supplied. Turn o the power to check the CHARGE LED being turned o
before starting connection or inspection. Failure to do so may result in
electric shock.
Repair, disassembly and modication
yDo not disassemble or modify the driver. This may cause electric shock or
injury. Refer all such internal inspections and repairs to the Oriental Motor
sales oce from which you purchased the product.
General
yDo not use the driver beyond its specications. Doing so may result in
electric shock, injury, or damage to equipment.
yKeep your ngers and objects out of the openings in the driver. Failure to
do so may result in re, electric shock, or injury.
yDo not touch the driver during operation or immediately after stopping.
The surface is hot, and this may cause a skin burn(s).
Installation
yDo not leave anything around the driver that would obstruct ventilation.
Doing so may result in damage to equipment.
Connection
yThe data edit connector (CN4) and the analog I/O connector (CN6) on the
driver are not electrically insulated. When grounding the positive terminal
of the power supply, do not connect any equipment (PC, etc.) whose
negative terminal is grounded. Doing so may cause the driver and these
equipment to short, damaging both.
Operation
yProvide an emergency-stop device or emergency-stop circuit external to
the equipment so that the entire equipment will operate safely in the event
of a system failure or malfunction. Failure to do so may result in injury.
yBefore supplying power to the driver, turn all input signals to the driver to
OFF. Otherwise, the motor may suddenly start when the power is turned
on, leading to injury or damage to equipment.
yWhen moving the moving part manually, put the motor into a non-
excitation state. Continuing the work while the motor is in an excitation
state may result in injury.
yUse a 24 VDC power supply that has been given reinforced insulation
between the primary side and secondary side. Failure to do so may cause
electric shock.
yImmediately when a problem occurred, stop operation and turn o the
driver power supply. Failure to do so may result in re, electric shock, or
injury.
yTo prevent electric shock, use only an insulated screwdriver to adjust the
driver’s switches.
Maintenance and inspection

Precautions for use
•Be sure to use our cable to connect the motor and the driver.
If a exible cable or cable longer than 3 m (9.8 ft.) is to be used, be sure to
purchase our cable separately. Check on the Oriental Motor Website for the
model name of cables.
•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 the dielectric strength
test with the motor and the driver connected may result in damage to the
product.
•Noise elimination measures
Refer to the USER MANUAL for noise elimination measures.
•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 writing the data
and cause an EEPROM error alarm to generate. The non-volatile memory can
be rewritten approximately 100,000 times.
•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
•Motor excitation at power ON
When the driver has been set to lock the servo after the motor stops in the
position control mode or speed control mode: Turning on the power supply
will not excite the motor. To excite the motor, you must turn the S-ON input
ON.
You can 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 the data setter OPX-2A.
•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.
The factory setting is to use the internal regeneration resistor. Note, however,
that the internal regeneration resistor does not support continuous
regenerative operation, gravitational operation or other operations involving
up/down movements, or frequent repeating of sudden starting/stopping of
a large inertial load. If any of these operations must be performed, use our
regeneration resistor. Check on the Oriental Motor Website for the model
name.
•Note on connecting a power supply whose positive terminal is
grounded
The data edit connector (CN4) and the analog I/O connector (CN6) on the
driver are not electrically insulated. When grounding the positive terminal of
the power supply, do not connect any equipment (PC, etc.) whose negative
terminal is grounded. Doing so may cause the driver and these equipment to
short, damaging both. Use the OPX-2A to set data, etc.
