Abstract
In an injection molding machine, a predetermined torque limit value set in advance and acceleration/deceleration torque calculated by an acceleration/deceleration torque calculation section are added to set an output torque limit value for a motor. By this operation, quick acceleration or deceleration can be achieved in an injection process, and breakage of a mold and mechanism section of the injection molding machine can be prevented.
