what you want to ask is what should I do if the clip of the steamed bread setting machine cannot be lifted? The specific operations are as follows:

1. Check whether the servo system is stable and whether the circuit board maintenance detection current is stable.

2. The cross coupling of the pulse encoder is damaged, which causes the shaft speed to be out of sync with the detected speed. Replace the coupling.

3. Remove the brush of the tachometer, polish it with steel sandpaper several times, and clean the dirt of the commutator at the same time, and then reinstall it.
