ELEVATOR SPEED CONTROL DEVICE

摘要

The device is designed to control the speed of an elevator by compensating the speed according to the vibration of a rope generating at the speed control. The device includes : a speed control section (1) for comparing a speed command signal(V1) and an actual speed detection signal (V2) and controlling the speed with the current command signal; an adder (24) for adding vibrating compensation signal; a current control meter (19) for controlling signal from the adder (24); a multiplier (17) for multiplying output signal of the current control meter (19) with the torque; an electric motor (18); and a vibration compensation sector (20).
