The performance comparison and precautions of servo motors, the difference between control accuracy and low-frequency characteristics, etc. are all worth noting. This article will provide you with some very important knowledge of servo motor performance comparison and precautions to share with you.
As an open-loop control system, the servo motor has an essential connection with modern digital control technology. Servo motors are widely used in current CNC systems. With the emergence of all-digital AC servo systems, the application of AC servo motors in digital control systems is becoming more and more extensive. In order to adapt to the development trend of digital control, most motion control systems use servo motors or full-digital AC servo motors as executive motors. Although the two control methods (pulse train and direction signal) are similar, they are quite different in terms of performance and application.
