PURPOSE: To reduce the effect of wind at the time of passing each other by providing a means detecting the passing of elevators from the positions and call register information of one elevator and the other elevator in advance, and setting the value of the speed command at the time of an ordinary travel to a prescribed value or below from the detected result.
CONSTITUTION: An inverter control device 11A and a microcomputer device 12A are incorporated in the control device 10A of an elevator A (same for B). The microcomputer device 12A is provided with a speed command generating device 121A, a call registering device 124A registering the car call and landing call, a position signal generator 123A generating the elevator position signal from the output of a pulse generator 5A, and a passing detecting device 122A detecting whether the elevators A, B pass each other or not from the call register information and position information of the elevator A and the call register information and position information of the elevator B. When passing each other is expected, the speed command outputted from the speed command generating device 121A is limited to a prescribed value or below.
