An injection molding machine uses a controller to effectively control its operation. The controller may determine and/or receive information regarding the machine's maximum load capacity, and may also determine a current operational load value of the machine. The controller also may determine a number of set points used to operate the machine. The controller may cause the machine to operate at these set points, thereby resulting in the machine operating at or below the maximum load value by adjusting any number of machine parameters associated with the injection molding machine.
