WARNING
Thank you for purchasing an Oriental Motor product.
This Operating Manual describes product handling procedures and safety precautions.
• Please read it thoroughly to ensure safe operation.
• Always keep the manual where it is readily available.
• Do not disassemble or modify the motor and gearhead. Doing so may result in
injury or damage to equipment. Refer all such internal inspections and repairs to
the branch or sales office from which you purchased the product.
• Only qualified and educated personnel should be allowed to perform
installation, connection, operation and inspection/troubleshooting of the
product. Handling by unqualified and uneducated personnel may result in fire,
injury or damage to equipment.
• Use a motor, gearhead, and driver only in the specified combination. An
incorrect combination may cause fire or damage to equipment.
• Install the motor, gearhead and driver in an enclosure. Failure to do so may result
in injury.
• Do not use the motor and gearhead beyond the specifications. Doing so may
result in fire, injury or damage to equipment.
• Do not touch the motor and gearhead while operating or immediately after
stopping. The surfaces of the motor and gearhead are hot, and it may cause a
skin burn(s).
• Do not leave anything around the motor that would obstruct ventilation. Doing
so may result in damage to equipment.
• Do not lift up the product by holding the output shaft or the motor cable. Doing
so may result in injury.
• Do not touch the motor output shaft (end or pinion) with bare hands. Doing so
may cause injury.
• When assembling the motor (pinion shaft) with the gearhead, exercise caution
not to pinch your fingers or other parts of your body between the motor and
gearhead. Injury may result.
• When installing the motor or gearhead in the equipment, exercise caution not
to pinch your fingers or other parts of your body between the equipment and
motor or gearhead. Injury may result.
• Do not touch the rotating part (output shaft) while operating the motor. Doing
so may cause injury.
• Securely install the motor and gearhead to the mounting plate. Inappropriate
installation may cause the motor and gearhead to detach and fall, resulting in
injury or damage to equipment.
• Provide a cover over the rotating part (output shaft) of the motor or gearhead.
Failure to do so may result in injury.
• Securely install a load on the output shaft of the motor or gearhead.
Inappropriate installation may result in injury.
• Be sure to ground the motor and driver to prevent them from being damaged
by static electricity. Failure to do so may result in fire or damage to equipment.
• 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 figure. Failure to do so may
result in a skin burn(s).
Precautions for use
This section explains restrictions and requirements the user should consider when using
the product.
z Be sure to match the motor output power with the driver output
power.
z Connecting the motor and driver
Use a connection cable (sold separately) when extending the wiring distance between the
motor and the driver. The maximum extension distance including the length of the motor
cable should be 2 m (6.6 ft.).
z Do not perform gravitational operation (vertical drive).
If this product is performed operation (i.e. gravitational operation) in which the motor
output shaft is turned from the load side, the motor speed cannot be controlled. In
addition, gravitational operation will cause the internal voltage of the driver to exceed the
permissible value, thereby triggering the protective function and causing the motor to
coast to a stop. If this happens, there is a possibility that the load will drop.
