Abstract

PURPOSE:To eliminate an overshoot at accelerating and decelerating time even in case of large inertial load by providing an overshoot preventing feedback circuit for suppressing the integrating amplification factor of a proportional integrating amplifier when the output of the amplifier exceeds the prescribed value. CONSTITUTION:A speed control amplifier SC outputs a current reference signal in response to a deviation of the outputs of between a speed setter SRH and a tachometer generator TG, and a current control amplifier CC applies a deviation between current reference signal of the amplifier CC and a current signal detected by a current transformer CT to a phase controller PHC. The amplifier SC normally operates as a proportional integrating amplifier. On the other hand, when the output signal of the speed control amplifier becomes the set value or higher, a current is flowed to a diode D to operate as the primary delay amplifier. Thus, it can be regulated to eliminate an overshoot.
