Abstract
A position control apparatus has a target setting unit for setting a target position in a direction of the control axis of the controlled object able to be moved in directions of a plurality of control axes by moving unit; a position control unit for independently positioning the controlled object to the target position in the direction of the control axis set by the target position setting unit; and a position correcting unit for correcting the target positions in directions of other control axes by compensation amounts for correcting positioning derivation in directions of other control axes occurring when positioning the controlled object to a first target position in the direction of one control axis among the plurality of control axes and then reversing the feed direction from that first target position and positioning to a second target position.
