ABSTRACT:
A current to be fed to a stepping motor for driving is determined by an operating circuit to which are input digital values converted from analog values representing various factors which may affect the stepping motor driving current. The results output from the operating circuit are sent to counters operated in response to a clock pulse signal supplied from an oscillator to thereby generate a pulse-width-modulation (PWM) signal to a stepping motor driving circuit through an output control circuit. The stepping motor driving current may be controlled in dependence on the values of PWL and PWH of the PWM signal.
