Category: Alarm
Cause
- The drive power cable (U V W) is short-circuited to ground
- The motor is short-circuited to ground
- Drive fault
Corrective action
- Disconnect the motor cable and measure whether each drive power cable U V W is short-circuited to ground (PE). Rewire or replace the drive power cable.
- After ensuring that the drive power cable and motor cable are securely connected, measure whether the insulation resistance between each drive U V W terminal and the ground wire (PE) is in the megohm (MΩ) range. Replace the motor.
- Remove the drive power cable from the servo drive. If the fault is still reported after repeatedly powering on, replace the servo drive.
