Specifications
• Maximum holding torque refers to the holding torque at motor standstill when the rated current is supplied to the
motor (5-phase excitation). Use this value to compare motor torque performance. When using the motor with the
included 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.)
Note
•
Do not measure insulation resistance or perform the dielectric withstand test while the motor and driver are connected.

Full Step (0.72°) at “photocoupler OFF”
Half Step (0.36°) 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.
