Category: Alarm

Cause

Condition: Abnormal encoder internal memory and internal counter. Causes:

1. Encoder internal error (abnormal internal memory and internal counter).
2. The motor rotates at power on because of mechanical inertia or other factors.

Corrective action

1. Ensure that the motor grounding terminal is securely grounded. Connect the power cable grounding terminal (yellow-green) to the drive heat sink (Heat Sink).
2. Check whether the encoder signal cable is normal. Separate the encoder signal cable from power cables and high-current wiring to prevent interference.
3. Check whether the position detector cable is shielded.
4. Ensure that the motor shaft remains stationary at the instant of power on. Power on again to clear.
