Abstract:
1. A method for controlling a molding machine, said method comprising: setting up a reference value as a standard to prevent temperatures of electric motors which drive each units of the molding machine from exceeding an allowable range; inputting molding condition data, the data determining operating conditions of the molding machine; storing the reference value and the molding condition data; calculating to analyze the molding condition data to generate a torque command value for producing a torque to the rotating shaft of the electric motor of the holding machine and to calculate at least an integrated value over time of a function of the torque command value to calculate an effective value of the torque command value; driving the electric motors based on the torque command value; and displaying an table showing the effective value and the reference value arranged in comparison as an guide when an operator for the molding machine prepares the molding condition data.
