When implementing an origin reset, operating conditions for the origin reset are corrected in correspondence to changes in operating conditions such as the source voltage to implement an accurate origin reset. Changes in the operating conditions for actuator are detected and if the operating conditions for the actuator have changed in the direction in which the drive force on a member to be driven is reduced, a correction is performed by a means for initial reset control setting in the direction in which the drive torque is increased for the initial reset control and a correction is performed by a means for return control setting to increase the drive torque and to reduce the number of steps during return control, whereas when the operating conditions for the actuator have changed in the direction in which the drive force on the drive member is increased, a correction is performed by the means for initial reset control in the direction in which the drive torque is reduced during the initial reset control, and a correction is performed by the means for return control setting to reduce the drive torque and to increase the number of return steps during the return control.
