Title:
ELEVATOR CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/207830
Kind Code:
A1
Abstract:
Provided is an elevator control apparatus (8) capable of determining whether a suitable current sensor (6) is used or not. The elevator control apparatus is provided with: a current controller (14) that outputs, on the basis of an inputted current command, a voltage command to a motor (2) that drives a car (4) of an elevator; a current detecting section (11) that detects a current value from a current sensor that detects a drive current flowing in the motor, said current value corresponding to the drive current; a car load detecting section (12); and a determining section (15b), which acquires a first current value detected by means of the current detecting section when the current controller outputs a voltage command corresponding to a load of the car in a state wherein the rotation of the motor is braked, and which acquires a second current value detected by means of the current detecting section when the current controller outputs the voltage command, such that the motor does not rotate in a state wherein rotation of the motor is not braked, and which determines whether the current sensor is normal or not on the basis of the first current value and the second current value.
