PURPOSE:To shorten the delay when a motor reversely rotates by shortcircuiting an integrating capacitor of a momentary speed amplified input with a rotating direction inverting signal pulse of a motor. CONSTITUTION:A proportional integrating controller composed of an operational amplifier Q1, resistors R1-R4 and an integrating capacitor C1 proportionally integrates a deviation between a motor speed command Vs and a motor speed Vd, and outputs a current command Is. When a direction inverting signal pulse is input from a command function generator, a relay R is turned ON for a short time. Thus the capacitor C1 is discharged, and the command Is momentarily becomes 0. When the relay R is OFF, the command Is is increased in reverse polarity. Thus, the response delay of the motor is shortened. |
