A kind of the pulse control mode, the drive and motor closedloop, but not to the numerical control system, the feedback device, in a sense, can open loop control called the servo control.
Adopting ac servo motor as the driving device, can the dc servo motor and a high precision, high performance as the half closedloop or closed loop control system.
采用交流伺服电机作为驱动器件,可以和直流伺服电机一样构成高精度,高性能的半闭环或闭环控制系统。
