Cause
Encoder internal error (internal calculation error).
Corrective action
- Ensure that the motor grounding terminal is securely grounded. Connect the power cable grounding terminal (yellow-green) to the drive heat sink (Heat Sink).
- Check whether the encoder signal cable is normal. Separate the encoder signal cable from power cables and high-current wiring to prevent interference.
- Use shielded encoder cable, bring out the shield, and ground it correctly.
- Check motor speed and ensure it is within the rated range. If none of the above measures improves the situation, return the motor to the dealer or manufacturer for repair. Power on again to clear.
