PURPOSE:To shorten an acceleration or deceleration time, by correcting the speed command signal of output generated from an acceleration or deceleration arithmetic means, with a speed command correcting means. CONSTITUTION:The input of speed setting signal and speed command signal to an acceleration or deceleration discriminating circuit 4 is provided, and it is discriminated whether a motor is accelerated or decelerated. The input of acceleration or deceleration discriminating signal, a current detecting value, and the speed command signal to a speed command signal correcting circuit 6 is provided. As a result, under the accelerating operation of the motor, from the speed command signal correcting circuit 6, correction command is applied to an acceleration or deceleration arithmetic circuit 3, and motor current is controlled to be always set between 95 % and 100 %. At the time of decelerating operation, the motor current is controlled to be set between zero and 5 %. |
