The outlook of ac servo
In modern CNC system，AC servo replace DC Servo motor and software controlled servo control has become development trend of servo technology, thus Resulting in the application of CNC machine tool servo and spindle device exchange of digital drive system. With the raise of microprocessor and all-digital AC servo system, the computing speed of numerical control systems greatly improve, the sampling time is greatly reduced. Servo control hardware convert into software servo control has significantly improved the performance of the servo system. For example OSP-U10/U100 network NC system is a high performance servo control loop servo motor controls network; it has achieved a distributed configuration and Self-regulation for all of its servo control devices and components. The development of these technologies make the servo system performance has improved .
