Adjusting the motor’s run current
1. Turn the DC check switch to the “ON.”
2. Switch on the driver’s power supply.
3. Turning the motor’s run-current adjustment
control in the counter-clockwise direction
reduces the current. One-half the value
displayed on the ammeter is the current per
phase of the motor.
(Example: 5.6 A = 2.8 A/phase)

Note
• After adjusting the run current, always return the current check switch to the “OFF.” If
this switch is set to “ON,” when the motor stops the motor current does not decrease to
the motor-stop current level.
• Always adjust the run current to no more than value of rated current. Higher current can
damage the motor and driver.
4. After adjusting the run control, return the current check switch to the “OFF.”
The scale values are not displayed on the control.
