PURPOSE: An operation speed control method for an elevator is provided for a car not to be shaken at a stop motion for exactly measuring story height by correctly establishing a car. CONSTITUTION: As an error in story height occurs while the required measurement of the story height in a safe state, the location of a car is decided to be placed in the door zone of the lowest floor. By the car in different door zone, the car is returned to the lowest floor at low speed. Then, the start command of a story height is inputted by an operation control unit for measuring the story height. The car is continuously accelerated at the maximum speed of the lowest speed while confirming the input of the operation signal of a highest floor slowdown switch and a door zone detect signal. Thus, reduction speed is calculated through dividing the maximum speed of at the lowest speed by half of the door zone length. A deceleration operation is started by calculating the equation, that is, speed = the maximum speed of the lowest speed - (125mm - the remained distance * reduction speed). The operation for measuring story height is stopped by a stop command as the car is moved to the distance corresponding to half of a location detector.
