<p>A system for controlling the revolution of a screw in an injection molding machine, wherein an injection shaft 2'' and a screw (2) are driven by electric motors (20) and (22). Output signals of a position detector means (21) of the injection shaft are input to an error register (35-1), the position detector means (21) being designed to obtain rotational data of the electric motor (22) that drives the injection shaft 2''. By monitoring the error register (35-1), the position of the injection shaft is detected, and the number of revolutions of the screw (2) corresponding to the position of the injection shaft 2'' is obtained by utilizing the override function.</p> |
