Abstract

PURPOSE:To improve starting characteristic of a servo circuit by activating a servo system under keeping an artificial motor circuit equivalent ot a motor in operation at the time of motor starting. CONSTITUTION:A DC voltage from a DC supply 22 is supplied to a motor 1 at starting, an output of a voltage comparing circuit 9 is supplied to an input end of an artificial motor circuit 21, and a frequency signal obtainable throught the artificial motor circuit 21 is supplied to a digital phase comparing circuit 4 and a frequency-voltage converting circuit 10. When a frequency signal from a frequency generator 2 exceeds a DC voltage 27 and the output of the voltage comparing circuit 9 exceeds the DC voltage 27, switch circuits 18-20 are charged to a terminal N side. Thus the frequency signal is supplied to the digital phase comparing circuit 4 and the frequency voltage converting circuit 10, and the output of the voltage comparing circuit 9 is supplied to the motor 1 through a drive amplifier 11.
