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, electric shock, injury, or damage to equipment.
•
The motor is Class
Ⅰ
equipment. Install the motor so as to avoid contact
with hands, or ground it to prevent the risk of electric shock.
•
Use a motor and driver only in the specified combination. Failure to do so
may result in fire, electric shock, or damage to equipment.
•
Always turn off the power before performing maintenance or inspection.
Failure to do so may result in electric shock.
•
Do not use the motor beyond the specifications. Doing so may result in
fire, electric shock, injury or damage to equipment.
•
Do not touch the motor while operating or immediately after stopping.
The surface of the motor is 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 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 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 in equipment, exercise caution not to pinch
your fingers or other parts of your body between the equipment and
motor. Injury may result.
•
Do not touch the rotating part (output shaft) while operating the motor.
Doing so may cause injury.
•
Securely install the motor to the mounting plate. Inappropriate installation
may cause the motor to detach and fall, resulting in injury or damage to
equipment.
•
Provide a cover over the rotating part (output shaft). Failure to do so may
result in injury.
•
Securely install a load on the output shaft. 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).

•
Dispose the product correctly in accordance with laws and regulations, or
instructions of local governments.
Precautions for use
Be sure to match the motor output power with the driver output power.
z
Connecting the motor and driver
Use an accessory connection cable (sold separately) when extending the wiring
distance between the motor and the driver.
z
Grease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern
over possible environmental damage resulting from the leakage of grease,
check for grease stains during regular inspections. Alternatively, install an oil pan
or other device to prevent leakage from causing further damage. Oil leakage
may lead to problems in the customer’s equipment or products.
z
Caution when using under low temperature environment
When an ambient temperature is low, since the load torque may increase by the
oil seal or viscosity increment of grease used in the gearhead, the output torque
may decrease or an overload alarm may generate. However, as time passes, the
oil seal or grease is warmed up, and the motor can be driven without generating
an overload alarm.
