Four control modes of servo drive

1.Feedback compensation open loop control. The accuracy of open-loop system is low, because the step error , start stop error and mechanical system error of servo driver will directly affect the positioning accuracy. This system has the advantages of both open-loop and closed-loop, that is, it has the stability of open-loop and the accuracy of closed-loop.
