Abstract

PURPOSE:To contrive the enlargement of the control range, by discriminating whether control voltage is less than the minimum value of threshold value or not to stop the control of the switching circuit by the output from a monostable multivibrator. CONSTITUTION:The input signal and feedback signal are compared by the servo- amplifier 1 for control voltage CV supplied to the monostable multivibrator 3 with the control of the sweep time thereof to control a motor 2 via the switching circuit 5. Besides, comparison voltage Vr corresponding to the minimum value of the threshold voltage of the multivibrator 3 is provided to break and make an AND gate 7 via a comparator 6. Therefore, when the control voltage CV is less than the minimum value of the threshold voltage, the control can be stopped for the switching circuit 5 with the reduction of the mean value of current flowing through the motor 2 to enlarge the range of control.
