<P>PROBLEM TO BE SOLVED: To provide a voltage monitoring method which can evaluate influence of the quality of three-phase AC voltage supplied from the outside on a molded article, and can prevent a trouble due to defect of the three-phase AC voltage. <P>SOLUTION: The voltage monitoring method of the electric injection molding machine measures a voltage value of the three-phase AC voltage supplied to the electric injection molding machine (1), records in a controller (3) in a predetermined cycle or by being synchronized with a molding cycle, records the maximum voltage value and the minimum voltage value between the previous recording timing and the present recording timing, and stops the electric injection molding machine (1) when the measured voltage value exceeds the set allowable range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
