PURPOSE:To improve a level holding capacity by providing a speed command control circuit for carrying out the speed command of a riding cage, and previously rotating a pump in a defined condition. CONSTITUTION:When an elevator sinks after stoppage due to the loading of baggage or the riding-in of riders, etc., as the sinking is detected by a position detecting circuit 130, a driving motor is immediately rotated. Then, when a starting command of an inching command, etc., is outputted, pulses are outputted to carry out a floor aligning correction. In this case, approx. 2-sec. starting delay time is generated from the output of the inching command by detecting sinking to the start of inching. At this time, if a sinking of 2mm is detected, the starting delay time can be reduced to 1.5sec. by rotating the driving motor. Also, when a user passes through a photo-electric device under a condition of stopping by a hall call without a cage call, since the cage positively sinks, a pump may be previously rotated together with the ON of the photo-electric device to carry out inching. Thereby, rapid inching can be carried out. |
