- The origin proximity switch is an inductive proximity sensor. Its installation position provides the origin information of linear motion. Both the left and right limit switches are micro switches with contacts, which are used to provide protection signals in case of overtravel fault: when the sliding slide passes the left or right limit position in motion, the limit switch will act, thus sending the overtravel fault signal to the system.（ ）
- The servo system has a good tracking ability to the given position signal, so it can still accurately reach the target position when it runs again after suspension.（ ）
