Precautions for use
Be sure to match the motor output power with the driver output power.
z
Connecting the motor and driver
To connect the motor and driver, always use the dedicated connection
cable (sold separately).
Limit the number of times so that attaching/detaching between the
connection cable and the motor or driver will not exceed 100 times.
z
Connection cable
Do not apply a strong force on the locking lever of the connector for
motor connection. Applying a strong force on the locking lever may cause
damage. Refer to p.5 for details.
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.
z
Do not conduct the insulation resistance measurement or
dielectric strength test with the motor and driver connected.
Conducting the insulation resistance measurement or dielectric strength
test with the motor and driver connected may result in damage to the
product.
z
Rotation direction of the output shaft
The relations of the motor output shaft and gearhead output shaft are
described in the figure below.
The figure shows the foot mount gearhead. The parallel shaft gearhead also
rotates in the same direction.

Check the operating manual supplied with the driver for the rotation
direction of the motor output shaft and the setting method.
About rotation speed and gear ratio
z
Maximum rotation speed 3600 r/min
Use the motor in conditions where the motor rotation speed is
3600 r/min or lower.
