ABSTRACT:
There is provided a molding machine controlling unit and method capable of preventing the operation of a molding machine from suddenly stopping due to the temperature of an electric motor. The control unit comprises: a calculating part40for analyzing molding condition data to generate a command value for producing a torque to the rotating shafts of electric motors71through73of an injection molding machine and to calculate an effective value on the basis of the command value; an entry part30for entering a reference value, which is to be compared with the effective value, and the molding condition data; a storing part35for storing the reference value and the molding condition data; a display part50for displaying the effective value and the reference value; and driving parts61through63for entering the command value to drive the rotating shafts of the electric motors, wherein the effective value and the reference value are displayed as a standard for preparing the molding condition data so that the effective value does not exceed the reference value.
