Safety precautions
5
Maintenance and inspection
Do not touch the motor or driver when conducting the insulation resistance measurement
or dielectric strength test.
Accidental contact may result in electric
shock.
Do not touch the connection terminals on the driver immediately (until the CHARGE LED
turns o) after the power is turned o.
Always turn o the power before performing maintenance or inspection.
Regularly check the openings in the driver for accumulated dust. Accumulated dust may cause re.
Repair, disassembly and modication
Do not disassemble or modify the motor, gearhead and driver. Refer all such internal
inspections and repairs to the branch or sales oce from which you purchased the product.
This may result in electric shock, injury
or equipment damage.
Handling of this product
Do not use the motor, gearhead, driver, and regeneration resistor in a state of exceeding the
specication values.
Doing so may result in re, electric shock,
injury or equipment damage.
Do not insert an object into the openings in the driver.
Do not touch the motor, gearhead, driver, and regeneration resistor while operating or for a
certain time after stopping.
The surface of the motor, gearhead,
driver, and regeneration resistor may be
hot, thereby causing a skin burn(s).
Installation
Do not leave anything around the motor and driver that would obstruct ventilation.
Doing so may result in damage to
equipment.
Securely install the motor, gearhead and driver to the mounting plates.
Inappropriate installation may cause
the motor, gearhead or driver to detach
and fall, resulting in injury or damage to
equipment.
Connection
Be sure to ground the motor and driver to prevent them from being damaged by static
electricity.
Failure to do so may result in re or
damage to equipment.
For the power supply of I/O signals, use a DC power supply with reinforced insulation on its
primary and secondary sides.
Failure to do so may result in electric
shock.
Operation
Do not touch the rotating part (output shaft) while operating the motor.
This may result in injury.
Provide 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.
Immediately when trouble has occurred, stop operation and turn o the driver power.
Failure to do so may result in re,
electrical shock or injury.
The motor surface temperature may exceed 70 °C (158°F) even under normal
operating conditions. If the operator is allowed to approach the motor in
operation, attach a warning label in a conspicuous position as shown in the gure.
Failure to do so may result in a skin
burn(s).

Warning information
A warning label with handling instructions is attached
on the driver.
Be sure to observe the instructions on the label when
handling the driver.
