Abstract
A method for controlling a motor-driven injection molding machine which includes a plurality of drive motors. In the method, load current flowing through at least one drive motor serving as a drive source is detected in order to estimate heat generation value of the drive motor. When the estimated heat generation value reaches a preset stopping point, the drive motor is stopped. When the estimated heat generation value reaches a preset alarming point, which is lower than the stopping point, an alarm is issued.
