SERVOMOTOR CONTROL SYSTEM FOR MULTI-AXES

摘要

A servomotor control system for multi-axes in which a single servo-amplifier can operate m rotational speed control loops and m current control loops as well for m servomotors simultaneously, where m is a predetermined integer greater than unity, while a single positioning controller with a signal teaching box can handle n servo-amplifiers in parallel, where n is a predetermined integer greater than unity, thereby mn servomotors in total can be controlled by a single system. In the system of the invention, the multiple servomotors can be divided into groups each including up to six servomotors to be controlled as a group and independently from servomotors belonging to other groups. The system of the invention can easily be expanded by a minimum addition of servo-amplifiers and/or positioning controllers to include servomotors more than mn, in which addition of one or more teaching boxes is possible whenever they become necessary.
