Category: Warning

Cause

1. Encoder fault
2. Motor encoder wiring abnormal (for example, a broken wire)
3. Motor encoder wiring subject to interference (for example, no shielded twisted-pair cable, coupling with motor power cables, or an insecure drive grounding connection)
4. Strong interference sources near the drive

Corrective action

1. Replace the encoder
2. Check the motor encoder wiring and ensure that it is correct and meets wiring requirements
3. Add ferrite cores to the encoder and motor power cables
4. Securely connect the drive grounding conductor
5. Remove strong interference sources around the drive, or the drive and nearby strong interference sources separately
