Cause

1. Inappropriate drive regulator parameter settings cause excessive speed tracking overshoot
2. Encoder data transmission subject to interference
3. Encoder damaged

Corrective action

1. Optimize the regulator parameters to improve speed tracking performance
2. Strengthen interference suppression for the encoder cable, for example by adding ferrite cores, using shielded twisted-pair cables, and ensuring reliable grounding
3. Replace the encoder
