2.Frequently asked questions about drives
1）What are the advantages of subdividing servo drives?
●Since the step angle of each step is reduced, the step uniformity is improved, so the control
accuracy can be improved.
●It can greatly reduce the vibration of the motor. Low-frequency oscillation is an inherent
characteristic of the stepper motor. Subdivision is the best way to eliminate it.
