PROBLEM TO BE SOLVED: To provide an elevator operation control which is able to limit an elevator operating speed in case of emergency operation using a charging battery because of a power failure happening. SOLUTION: This elevator operation control device is composed of installing a battery charger, and it is provided with a power supply unit 17 outputting a specified control signal a1 after detecting the propriety of a supply from the main electric power source 1, an operation controller 18, receiving each input of the control signal a1 and another control signal being requested by a user, outputting a speed control signal b1 and a load compensating signal b2, and controlling an elevator system, a speed limiter 19S limiting speed of an AC motor 9 after receiving the power consumption of the AC motor 9 calculated from a speed signal of the AC motor 9 and a power consumption detector 19R, and a speed controller 19 controlling a rotational speed of the AC motor 9 after receiving each control signal to be outputted from those of load compensating signal b2 and speed limiter 19S, respectively. |
