ABSTRACT:
Apparatus and method for controlling a hydraulic actuator in an injection molding machine, where the hydraulic actuator moves in a linear or rotary manner to effect movement of an injection molding device, such as a mold clamp. A microcontroller is locally disposed adjacent to the actuator or the hydraulic fluid distribution manifold to cause the actuator to drive the device. The microcontroller is electrically coupled to the system control processor. This distributed control architecture increases system processing throughput, enhances reliability, and permits easier upgrades/repair. Preferably, the microcontroller is mounted on the manifold and controls all of the actuators supplied from that manifold.
