Abstract:
A stepping motor drive is provided, by which a recoil movement of a driven member upon an initialization action can be reduced. The stepping motor drive includes: a drive signal supply means which supplies a plurality of periodic drive signals having different phases from each other to generate a rotation torque in a stepping motor, one electric cycle being constructed by a plurality of excitation steps; a control means which makes the drive signal supply means supply the drive signal upon a initialization action in which a driven member connected with rotation of the stepping motor is made abut against a stopper; and a first storing means which stores a torque control parameter according to an inversion phase characteristic intrinsic to the stepping motor.
