Abstract

PURPOSE:To prevent the hunting of a pulse motor by controlling the revolution of the pulse motor following an input signal within an allowable speed range thereof so as to regulate it to the maximum level within the allowable range when the input signal exceeds the allowable revolution. CONSTITUTION:An input signal 22 is compared with an output of an integrating circuit 4 by means of comparators 5 and 6. When the input signal 22 is less than the output, a one-shot circuit 10 operates to reset a flip flop 9, so that the output of the integrating circuit 4 presents a tailing characteristic. When the input signal 22 is larger than it, the one shot circuit 11 operates to set the filp flop 9, so that the output of the integrating circut 4 presents a rising characteristic. When the input signal 22 is inputted with a rising (tailing) sharper than the rising (tailing) characteristic of the integrating circuit 4, the output of the circuit 4 converted into a pulse signal with a V/F converter 131 and taken out of an OR gate 21. Otherwise, the input signal 22 is converted into a pulse signal with a V/F converter 132 and released.
