Running control unit 13 first makes traction motor drive car Accelerating running to full gear value, is then traveled at the uniform speed with full gear value, is reaching
Run slowly until resting in predetermined floor by full gear value during to stop condition；When uplink/downlink floor is relatively low (for example the bottom of from
Layer runs to three layers), running control unit 13 first makes traction motor drive car Accelerating running, slows down when reaching stop condition
Run up to rest in predetermined floor.
Above-mentioned variable-speed elevator operation control system adjusts cage operation full gear value according to car weight, and creates fortune accordingly
Row curve is so that lift car improves the speed of service when passenger is less, so that traction motor plays maximal efficiency, simultaneously
Decrease the waiting time of passenger.
