In the synchronous Drive control manner of the injection molding machine which makes

摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine which carries out a synchronized control by each electric motor well in the injection molding machine which moves a movable section at least by two or more electric motors, and at the same time, can reduce stops at work of the injection molding machine as much as possible.;SOLUTION: A drive control method for the injection molding machine which moves the movable section at least by two or more electric motors comprises carrying out control to allow each electric motor 19a, 19b to follow-control to a command value V1 of a virtual master axis, and changing the command value V1 of the virtual master axis when the deflection of a measured value of at least one axis 34a to the command value V1 or a set value of the virtual master axis, or a deflection of mutual measured value of each axis 34a, 34b exceeds a first deflection A or coincides with the first deflection A.;COPYRIGHT: (C)2010,JPO&INPIT
