Abstract
A method of converting pulse frequency in a control circuit of a pulse motor which comprises converting the constant frequency of pulses into the voltage corresponding thereto, leading the pulses having said voltage to a charge and discharge circuit having a preset time constant, converting the voltage of the pulses outputted from the charge and discharge circuit into the frequency corresponding to change in the voltage, feeding the pulses outputted from a V/F converter to the exterior, and stopping the output of the pulses converted by the V/F converter when the count number of the input pulses having the constant frequency becomes coincident with the count number of the pulses outputted from the V/F converter.
