ABSTRACT:
An apparatus for decelerating an elevator at a terminating floor having a plurality of terminating detectors successively provided in the vicinity of the terminating floor for generating a terminating deceleration command value gradually decreasing upon operation of the detectors when the cage of the elevator approaches the terminating floor which comprises; a pulse generator for generating pulses corresponding to the moved distance of the cage; memories for storing the distances from the terminating floor to said respective terminating detectors; a counter for setting the distance information of the detectors of said memories upon operation of the detectors and counting the output pulses of said pulse generator, thereby subtracting the pulses from the set value; and a distance-to-speed converter for calculating the terminating deceleration command value corresponding to the output of said counter.
