ABSTRACT:
A control circuit for a step motor includes means for stepping the motor at a speed at which it can not be reliably stopped at a given step. The control circuit also includes a motor deceleration circuit that includes a bistable device, a pulse delay circuit with a given delay time and controlled by the bistable device, and a gating circuit all of which cooperate to decelerate the motor by supplying stepping pulses to the motor stator windings with a one step delay.
