Servo Drive Details

Tips: Speed control a AC servo motor
The rotation speed can be controlled by analog input or pulse frequency. When there is outer loop PID control of the upper computer control device, the speed mode can also be used for positioning. However, the position signal of the servo motor or the position signal of the direct load must be fed back to the upper computer for calculation. Speed mode also supports direct load outer loop detection position signal. At this time, the encoder at the servo motor shaft end only detects the motor speed, and the position signal is provided by the direct detection device at the final load end. This has the advantage of reducing errors in the intermediate transmission process and increasing the positioning accuracy of the entire system.
