Abstract

PURPOSE:To achieve high response, by limiting variation of output from a speed control amplifier when the difference between an output integrated with a predetermined positive or negative voltage corresponding to the polarity of output from a speed control amplifier and an output from the speed control amplifier exceeds over a predetermined level. CONSTITUTION:A speed control amplifier 18 obtains a difference v between a setting speed v0 and a speed v, and provides the difference v to a current control amplifier 24. An integrating circuit 50 integrates a constant voltage corresponding to the polarity of the output v from the speed control amplifier 18. When the difference ¦b-c¦ between an output (c) which inverted the polarity of the output v and an integrated output (b) exceeds over a bias voltage VB, comparators 72, 74 output a positive or negative voltage. Consequently, variation of the output v from the speed control amplifier 18 is limited, and high response can be obtained.
