Abstract
Response delay error is calculated from an instructed position based on a position of a moving body and a position instruction to detect reversal of a servo motor and to compare response delay error produced in reversal of the servo motor and threshold value. In the case where response delay error is a threshold value or greater, the value of the already determined compensation torque is updated into a value that enables the response delay error to be decreased, and allows the moving body to carry out circular arc complementary feed motion under the same condition to compensate, based on the updated compensation torque, instructed torque for instructing the servo motor when reversal of the servo motor is detected. Compensating the instructed torque and updating the compensation torque is repeated until the response delay error is at the threshold value or less. Thus, a reasonable compensation torque is determined such that response delay error at the time of reversal of the servo motor is minimized.
