The iSA decentralized controller is the basis for modular machines that are free of control cabinets. It has a three-phase power connection and provides both a dc bus supply for servo drives and integrated 24-V supply and control intelligence, including motion control. The controller’s compact design is completed by a lean, real-time Linux operating system. The system’s real-time capability is ensured via EtherCAT. The product also can be used in combination with other controllers as a gateway for Ethernet/IP and Profibus.
