• Maximum holding torque refers to the holding torque at motor standstill when the rated current is supplied to the
motor (5-phase excitation), with consideration given to the permissible strength of the gear. Use this value to
compare motor torque performance. When using the motor with the dedicated driver, the driver’s “Automatic
current cutback” function at motor standstill reduces maximum holding torque by approximately 50%.
• The power source input current value represents the maximum current. (The input current varies according to the
pulse frequency.)
• Permissible torque is the marginal value of the mechanical strength of the gear unit. Use the product with a total
torque (load and acceleration) less than the permissible torque.
• Maximum overhung load indicates the value measured at 10mm (0.39in.) from the tip of the gear output shaft.
Note
•
Do not measure insulation resistance or perform the dielectric withstand test while the motor and driver are connected.

Full Step at “photocoupler OFF” Half Step at “photocoupler ON”
When in the “photocoupler ON” state, the current to the motor is cut off and the motor shaft can be rotated manually.
When in the “photocoupler OFF” state, the current level set by the RUN switch is supplied to the motor.
When in the “photocoupler ON” state, the “Automatic Current Cutback” function at motor standstill is disabled.
When in the “photocoupler OFF” state, the “Automatic Current Cutback” function at motor standstill is activated.
