Abstract
An elevator control device which selectively employs an operational mode in which the cage of the elevator is run at a maximum rated speed or an operational mode in which the cage is run at a speed lower than the rated speed as determined by distance codes read out from a memory. The cage is accelerated in accordance with an acceleration signal the value of which is determined by the total distance between the start and stop floors. A deceleration instruction signal is produced in accordance with the difference between the acceleration instruction signal and the distance to the floor at which the cage is to be stopped. The acceleration instruction signal is compared with the deceleration instruction signal and a decision is made as to which is utilized as a speed instruction signal to a motor operating the elevator cage in accordance with which is the larger.
