Industry 4.0 controller is called IFC for short, users obtain more multiple intelligent function. For making machine tool to reach intelligent function, we provides IFC to combine with IO to connect sensors such as vibration, temperature and stress, through EtherCAT communication protocol to gain real-time and accurate data. For further, those data will be calculated and analyzed for informing machine to make compensation and protection. Additional, IFC can control both divided circle( not move with axis of Fanuc) and linear robot. Many users choose IFC to assist their machine to develop more innovation function.
