Abstract
A movable member encoder is used to detect the position of a movable member, and a correction value calculator calculates a correction value corresponding to the amount of displacement of the movable member from a reference position and the integration of the amount of displacement. The correction value calculated by the correction value calculator is then used in correcting a voltage instruction value output from a feed motor controller to a feed motor.
