Servo loop processor in association with a central processing unit for closed loop control of a servo system

摘要

A servo loop processor (2) is a dedicated controller for use with a main central processing unit (4) (CPU), through an appropriate interface (8,10) whereby closed loop control of a servo system (22) is achieved. Servo loop parameters as well as servo motor speed and/or position are downloaded from the main CPU (4) to the servo loop processor (2) through a configuration including a microcomputer (12) so that the main CPU (4) is free to perform other tasks.
