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.

A method of converting pulse frequency in a control circuit of a pulse motor comprising:
- converting the constant frequency input of pulses into a voltage indicative thereof in a F/V converter, inputting such corresponding voltage to a charge and discharge circuit having a preset time constant, converting the output voltage from said charge and discharge circuit into output pulses having changing frequencies corresponding to changes in the voltage in a V/F converter, feeding such output pulses to the circuit output and stopping the output of such output pulses when the number of such input pulses becomes coincident with the number of such output pulses.
