This Operating Manual describes product handling procedures and safety precautions.
y Please read it thoroughly to ensure safe operation.
y Always keep the manual where it is readily available.
y When 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 specific position in the event of an alarm.
Failure to do so may result in injury or damage to equipment.
y When 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
y The 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.
y Install the driver inside an enclosure. Failure to do so may result in electric shock or
injury.
Connection
y Always keep the power supply voltage of the driver within the specified range. Failure
to do so may result in fire or electric shock.
y Connect the cables securely according to the wiring diagram. Failure to do so may
result in fire or electric shock.
y Do not forcibly bend, pull, or pinch the connection cable. Doing so may result in fire or
electric shock.
Operation
y Turn off 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.
y Do 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
y Do not touch the connection terminals on the driver while the power is supplied or
for at least 10 minutes after turning off the power. Turn off the power to check the
CHARGE LED being turned off before starting connection or inspection.
Repair, disassembly, and modification
y Do not disassemble or modify the driver. Doing so may result in electric shock or
injury. Refer all such internal inspections and repairs to the Oriental Motor sales office
from which you purchased the product.
General
y Do not use the driver beyond its specifications. Doing so may result in electric shock,
injury, or damage to equipment.
y Keep your fingers and objects out of the openings in the driver. Failure to do so may
result in fire, electric shock, or injury.
y Do not touch the driver during operation or immediately after stopping. The surface is
hot, and this may cause a skin burn(s).
Installation
y Do not leave anything around the driver that would obstruct ventilation. Doing so
may result in damage to equipment.
Connection
y The data edit connector (CN4) and I/O signal connector (CN5) 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 equipment and driver to short, damaging both.
