  • Publication number: 20230302639
    Abstract: A control device for controlling a machine with axes having a corotational relation includes: axis position detectors; motor position detectors; a position command calculation unit calculating a position command for each of the axes based on an operation program; a position control unit outputting a speed command of each motor based on the position command and the detection position of the corresponding axis; a speed control unit controlling each motor based on the speed command; and a correction value calculation unit calculating a correction value for correcting, based on the corotational relation, the speed command of a motor with a to-be-controlled axis which is an axis rotating dependent on the corotational relation. The speed control unit corresponding to the to-be-controlled axis corrects the speed command based on the correction value so as to be applied to control of the motor with the to-be-controlled axis.
