Abstract:
A servomotor control system includes: an integrated control unit for integrally controlling servomotors; and servomotor units coupled with the integrated control unit and the servomotors. Each servomotor unit includes: a motor driver; a rotation detector of the servomotor; an original point detector for detecting an original point of the servomotor; a communication element for obtaining control information including rotation position instruction information from the integrated control unit; a rotation position calculator for calculating a current rotation position of the servomotor based on a rotation detection signal; a motor drive instruction element for outputting driving instruction information to the motor driver according to the control information and the current rotation position; and a current rotation position correction element for resetting the current rotation position to a predetermined original point when the original point detector detects the original point.
