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 test or dielectric strength test with the motor and
driver connected may result in damage to the product.

•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 motor surface temperature may exceed 100 °C (212 °F) under certain conditions
(operating ambient temperature, operating speed, duty cycle, etc.). To prevent the
bearings (ball bearings) from reaching its usable life quickly, use the motor in a condition
where the surface temperature does 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 case.

•Rotation direction of output ange of Harmonic geared type

The output ange of the Harmonic geared type rotates in the opposite direction to the
rotation direction of the motor output shaft.

•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.
