ABSTRACT:
A control device for a servo motor comprises feedforward means for correcting a speed reference obtained by a position control device by a correction amount obtained on the basis of an objective position or an objective speed of the servo motor so that a response delay of the position control device for obtaining a reference speed necessary to control the rotation angle position of the servo motor to an objective rotation angle position is compensated for while restricting vibration.
