Abstract
PURPOSE: To detec the abnormality of a control system in the deceleration operation periods of a door opening operation period, etc., by obtaining a trouble detector for detecting the surpassing of the speed of an elevator more than a fixed value as a trouble if said surpassing takes place even when the speed command signals of the elevator are in low speed.
CONSTITUTION: A trouble detector containing a simulated circuit 55 for putting out the transitional delay time of a motor control circuit is normally mounted to a controller that the output signals 7 of a speed detector 22 of a motor 21 for driving an elevator and the command signals 6 of a speed command generator are compared at a comparator 2, the deviated signals are sent to a generator field winding 16 to generate voltage corresponding to the deviated signals to an armature 15 of a generator and the voltage is fed to an armature of the motor 21. In this case, however, a 2nd speed detector 23 is further installed, the detected signals are setn to a level comparison circuit 25 and signals are put out which operate the relay 25 when the signals are not less than a level.
