<p>An elevator device operated based on a standard (overspeed level) varying according to the operating conditions of a car (2), comprising a position information correction means (80) for automatically correcting the errors of values for setting the standard, wherein the position information correction means (80) determines the overspeed level by using sequential information corresponding to the position of the car and corrects the sequential information by using intermittent information corresponding to the actual position of the car, whereby adjustment at site and maintenance over a long period can be eliminated, and an overspeed detection level can be easily varied according to the conditions of the car.</p> |
