Precautions for use
•When conducting the insulation resistance measurement and the
dielectric strength test, be sure to separate the connection between the
motor and the driver.
Conducting the insulation resistance measurement or withstand voltage test with the
motor and driver connected may result in injury or damage to equipment.
•Do not apply a radial load and axial load in excess of the specied
permissible limit
Operating the motor under an excessive radial load or axial load may damage the motor
bearings (ball bearings). Be sure to operate the motor within the specied permissible
limit of radial load and axial load.
•Motor surface temperature
The surface temperature on the motor case may exceed 100 °C (212 °F) depending on
operating conditions such as ambient temperature, operating speed, duty cycle and
others. To prevent the motor bearings (ball bearings) from reaching its usable life quickly,
use the motor in conditions where the surface temperature will not exceed 100 °C
(212 °F).
Use the geared motor in a condition where the gear case temperature does not exceed
70 °C (158 °F), in order to prevent deterioration of grease and parts in the gear part.
•Grease leakage
On rare occasions, a small amount of grease may ooze out from the geared motor. 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.

•Holding torque at standstill
The motor holding torque is reduced by the current cutback function of the driver at
motor standstill. When operating the motor, take account of the motor torque drop at
the time of stopping.
•Allowable torque
When operating the motor at a constant speed, use so that the torque does not exceed
the allowable torque in the specications. Operating the motor in excess of the allowable
torque may cause damage to the gear part.
•Speed range
Operate the motor at speeds within the speed range. Operating the motor at a speed
outside the speed range may result in a shorter gear life.
•Backlash
The gear output shaft is subject to backlash. To reduce the eect of backlash, perform
positioning operations from one direction only-either from the CW direction or the CCW
direction.
•Rotating direction of the gear output shaft
The relationship between the rotating direction of the motor shaft and that of the gear
output shaft changes as follows, depending on the gear type and gear ratio.
Model Gear ratio Rotation direction of the gear output shaft
PKP223 7.2, 36 Same as the motor output shaft

Connection
•When inserting the connector
Hold the connector main body, and insert it in straight securely. Inserting the connector
in an inclined state may result in damage to connector or a connection failure.
•When pulling out the connector
Pull out the connector in straight while releasing the lock part of the connector. Having
the motor lead wires or pulling out the connector in a state of being locked may damage
the connector.
Secure the lead wires at the connection part to prevent the connection
part from receiving stress due to the exing of the lead wires or the lead
wires’own mass. Also, do not excessively bend the lead wires near the
connection part of the connector. Applying stress on the motor lead wires
may cause poor contact or disconnection, leading to malfunction or heat
generation.
Bend excessively
Have length allowances
More than 4 times
of the diameter of
the lead wires.
Connection with the drivers of Oriental Motor
Refer to the following table when connecting with the drivers of Oriental Motor.
“Color” in the table represents the colors of lead wires of the connection cable (supplied
or accessory).
The motors of the model A and model B are dierent in pin assignments.
Wrong connection will not cause the motor to operate properly.
