ABSTRACT:
A pulse motor control device is provided with a microprocessor for presetting time data in a counter to determine a rotating speed of a pulse motor according to an interrupt signal, in which an overflow pulse from the counter is supplied as an interrupt signal to the microprocessor and is also applied as a phase data changing signal, which determines the period of the phase data, to a motor control circuit. A gate is provided at a prestage of the interrupt terminal of the microprocessor. When the pulse motor is driven at a constant speed, the gate is disabled to prohibit the interrupt signal from being applied to the microprocessor.
