ABSTRACT:
An elevator speed instruction generating system using an electronic computer to generate speed instruction data comprises a pulse generator adapted to generate a pulse whenever the cage runs a predetermined distance, a counter for subjecting the pulse thus generated to addition and subtraction according to the travelling direction of the cage, and memory means provided in the electronic computer for storing acceleration and deceleration instruction data. Acceleration instruction data are read out of the memory means every predetermined time in the acceleration operation, and in the deceleration operation deceleration instruction data corresponding to the differences between the absolute position of a destination floor and outputs of the counter are read. Adjustment of the elevator, which is required when it is installed in different buildings, can be achieved merely by changing the data stored in the memory means.
