Abstract

PURPOSE:To deny revolution due to inertia, and to stop a servomotor rapidly by forcedly supplying input having polarity reverse to error signals to the servomotor in a short time when the error signals enter an allowable error range. CONSTITUTION:The error voltage of an error detector 1 is inputted to a comparator 4 together with reference voltage VRef, and a change-over switch S1 is changed over to a terminal (b) from a terminal (a) by the output signals of the comparator 4 when the error voltage reaches the reference voltage VRef or lower. A polarity detecting circuit 5 outputs signals corresponding to the polarity of the error voltage to a polarity holding circuit 6, the polarity holding circuit 6 holds predetermined voltage having polarity reverse to the polarity of the error voltage for a fixed time and the predetermined voltage is inputted to a servo amplifier 2. Accordingly, voltage turning the servomotor 3 in the opposite direction is applied to the servomotor 3 driving the object P to be controlled, and the servomotor 3 is stopped rapidly. After a fixed time passes, the input voltage of the servo amplifier 2 is brought forcedly to zero potential.
