する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency operation device for an AC elevator, and more particularly to an emergency operation device for an AC elevator that switches to an emergency power source to perform an emergency operation of a main motor when a regular power supply fails. Regarding driving equipment.

点で問題があるので、エレベータの設備自体に非常運転
を行ない得る装置を設けることが切望されていた。Generally, when a power failure occurs in the service power of an elevator, the brakes are immediately applied and the car is stopped. Therefore, the stop position of the car is often a position where the passenger cannot be lowered by opening the door. As a result, the car becomes a closed room, giving passengers a great deal of anxiety, and even in the event of a power failure due to a fire in the building, even life is endangered. As a countermeasure against such an emergency, a large-scale building is equipped with a private power generation facility so that the car can be operated in an emergency even when there is a power outage. However, in a small building such as an apartment, there is a problem in terms of economy in installing a private power generation facility, and therefore it has been earnestly desired to provide a device capable of performing an emergency operation in the elevator facility itself.

得ることができた。Therefore, as an example of performing emergency operation, Japanese Patent Publication No. 57-5739
As described in Japanese Patent Laid-Open No. 2 (1994), there has been proposed one that performs an emergency operation with an emergency power source. In order to reduce the burden on the emergency power supply, the emergency operation device that performs this emergency operation uses the load detector in the car to perform descending operation if the passenger is 50% or more of the capacity, and conversely if it is less than 50%. It was controlled to perform ascending operation. In addition, the control was made so as to eliminate the large impulse of start-up due to the immediate switching from the regular power supply to which there was a power outage, so an emergency operation device for an AC elevator with good riding comfort and landing accuracy is obtained even during emergency operation. I was able to.

な非常運転によつて非常電源が無駄に消費されてしま
う。Since the conventional AC elevator emergency operation device was configured as described above, it is possible to perform emergency operation at any time if the regular power source is a power failure, and with the above-mentioned in-car load detector, it will be 50% or more of the capacity. If so, it started to drive up without passengers. For example, a user who is going to use an elevator now calls a hall from a certain hall, and in response to that, a waiting car runs. At this time, in the case where the utility power supply fails and the car is stopped, the emergency operation is performed even though there is no passenger to rescue. Therefore, the unnecessary power is wasted by the unnecessary emergency operation.
