Document Type and Number:
WIPO Patent Application WO/2019/111404
Kind Code:
A1
Abstract:
Provided is an elevator control device with which it is possible to detect erroneous wiring to a hoist even when a car is subjected to an emergency stop and movement in a downward direction is suppressed. This elevator control device detects erroneous wiring of a motor wire or erroneous wiring of an encoder wire on the basis of a determination result from a torque limit determination unit and a determination result from a stall determination unit after control of a synchronous motor has started so as to raise the car, from a state in which the synchronous motor has stopped. Providing the above configuration makes it possible to detect erroneous wiring to a hoist even when the car is subjected to an emergency stop and movement in a downward direction is suppressed.
