6.9 Group F8 PID control parameters
The commonly used closed-loop control systems can be divided into two types of
analog closed-loop and pulse closed-loop according to different feedback quantities. Figure
6-36 and Figure 6-37 shown the wiring diagrams of analog closed-loop control and pulse
feedback closed-loop control composed of drives.
