Cause : Encoder Loss comes when incorrect encoder parameters or faulty encoder wiring. This fault also comes when encoder is faulty.
- Check Wiring.
- If P047, P049, P051 [Speed Referencex] = 16 “Positioning” and A535 [Motor Fdbk Type] = 5 “Quad Check”, swap the Encoder channel inputs or swap any two motor leads.
- Replace encoder.
