Abstract
An input control circuit for a step motor is disclosed. The circuit includes three separate counters for selectively monitoring command pulses and motor pulses such that the rate of acceleration and the initial point of deceleration are independent of (i) the entry rate of command pulses and (ii) the entry timing. This permits operation of the step motor with an undedicated source of command pulses, e.g., a microprocessor.
