1. The common causes of mechanical oscillation (during acceleration/deceleration) causing such problems are: ① The pulse encoder is malfunctioning.At this moment, you should check whether the voltage on the feedback line terminal of the speed detection unit has dropped at a certain point. If there is a drop, it indicates that the pulse encoder is bad. Replace...
