Working Principle
24VDC power supply inputs to module internal isolated power conversion circuit to generate multi-group stable working voltage for motion control CPU, signal acquisition chips and communication transceivers. 32-bit industrial RISC main processor executes preloaded wafer handling motion control programs, outputs pulse/direction or CANopen motion commands to external servo drives to control wafer transfer robot positioning. Onboard analog front-end circuits continuously sample process sensor signals (vacuum, temperature, gas flow); digital input channels collect equipment safety interlock switch signals, all data is processed in real-time and uploaded to factory MES system via Ethernet. If safety interlock fault signal triggers, internal logic immediately stops all axis motion and outputs fault alarm digital signal to cabinet indicator lamp.
