Abstract

PURPOSE:To reduce the actuation shock of an elevator cage due to fluctuations of a load, by performing actuation while observing the output of a speed detecting circuit. CONSTITUTION:The output of a speed generator 6 coupled directly with an electric motor 1 and extracting a voltage proportional to its rotational frequency is inputted to a speed detecting circuit 7 as the actual-speed signal Vt of a cage 4. A computer 8 consists of a CPU9, ROM10, RAM11, converter 12, and data bus 13 and to the converter 12, an output signal from the speed detecting circuit 7, an actuation command signal 16, and a deceleration start signal 17 are supplied. An acceleration command generator 14, on the other hand, is supplied with a digital acceleration command signal Vp from the computer 8 to convert it into an analog acceleration command signal Vp, which is inputted to a controller 15 for control over the electric motor.
