Abstract
The duty of a current to be supplied to an injection motor is calculated on the basis of the ratio between set injection time for which the injection motor operates and molding cycle time, a shaft torque of the injection motor is calculated on the basis of a set maximum injection force of the injection molding condition, a maximum current for the injection motor is determined on the basis of the calculated shaft torque, and it is decided that the injection motor is overloaded, an alarm is given, a duty for a current that enables continuous molding is retrieved for the maximum current, a state that enables continuous molding is displayed and the molding cycle time determining the duty of the current that enables continuous molding is corrected when the current having the calculated desired duty is smaller than the maximum current.
