PROBLEM TO BE SOLVED: To prevent an injection molding cycle also from being prolonged without imposing an overload on a motor when an electromotive injection molding machine is controlled. SOLUTION: When ejection of an ejector device driven with a motor 21 of a motor-operated injection molding machine is controlled, the motor is at first driven by a low speed and a low torque, and the ejector device is ejected to a previously determined ejecting position. The ejector device stops a mechanical end motor. Then, a stop position of the motor is stored as a set ejecting position, and ejction of the ejector device is controlled according to the set ejecting position.
