Elevator device

Abstract

An elevator apparatus has a criterion (overspeed levels) that changes in accordance with an operational condition of a car. The elevator apparatus also has a position information correcting means that corrects an error in value that determines the criterion. In the elevator apparatus, the overspeed levels are determined using continuous information corresponding to car position, while the continuous information is corrected using intermittent information corresponding to actual car position. According to the elevator apparatus, on-the-spot adjustment or long-time maintenance becomes unnecessary, and overspeed detection levels can easily be changed in accordance with the operation conditions of the car.
