場合のエレベータ制御装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly, to an elevator control device when the load (or load; referred to as load in the present invention) in a car is no load or less than a predetermined load. Regarding

た。2. Description of the Related Art Conventionally, when a call occurs on another floor when there is no passenger in the car and there is no passenger in the car, from the viewpoint of servicing as fast as possible, the elevator is below the rated speed at that time I was rushing at the maximum speed I could get out.

【０００４】さらに最近、かごの軽量化，ビルの高層化
に伴うエレベータの高揚程化が図られつつある。More recently, the weight of a car has been reduced, and the height of an elevator has been increased in accordance with the height of a building.

とが懸念される。In the above prior art, the weight of the car reduces the inertia moment of the elevator, and if a power failure or some abnormality occurs during operation of the elevator with no load or in a state close to it, the emergency stop of the elevator will occur. However, during the short time from the braking command due to power failure detection or abnormality to the braking effect being exerted (this is called the idling period), the elevator inertia moment is small, so the car speed There is concern that the governor device may operate at the operating speed of the governor device.

There is concern that the governor device may operate at the operating speed of the governor device.

ある。An object of the present invention is to operate the elevator with a maximum speed lower than the rated speed even when the rated speed can be obtained when the elevator is operated with no load or with a load smaller than a predetermined load. By doing so, the car speed will not reach the operating speed of the governor device during the uncontrollable idle period at the time of emergency stop due to power outage (including momentary power failure) or abnormality, and unnecessary operation of the governor device will be prevented. To avoid it.

A comparing means for comparing and detecting that the load is smaller than the load, a judging means for judging the direction detected by the direction detecting means, and a maximum speed generated by the speed command generating means according to the results of the judging means and the comparing means is a rated speed. In the case of, the control device for the elevator is equipped with speed command changing means for changing the maximum speed to be lower than the rated speed. .
