Zero Servo Fault

The value set in the torque limit is too small.

Adjust torque limit-related parameters L7-01 to L7-04.

The load torque is too large.

Decrease the load torque.

Noise interference along the encoder cable

Isolate the encoder cable from the drive output line or a different source of electrical interference.
Note:

  • The drive detects this error if motor rotation position moves during Zero Servo.

  • Do a Fault Reset to clear the fault.
