Abstract Operational principle of traditional AC servo motor system used for static position control was introduced．Problem of lacking precision when AC servo motor system was used for dynamic position control was pointed out．Causation of inaccuracy when traditional AC servo motor system was used for dynamic position control was analysed．Solution based On high-speed terminal feedback was given．
