EtherCAT Master 4 (EM4)
The KSMC-ECAT EM4 is a powerful, PC-based EtherCAT Master Motion Controller built on an industrial x86 platform. Designed for real-time, high-precision control across various industrial applications, the EM4 transforms your Mini-ITX form factor PC into a full-fledged EtherCAT master — with no extra hardware required. The Class-A EtherCAT master controller supports Distributed Clocks, Cyclic PDOs, Cable Redundancy, and more. Combined with a proven motion engine used in over 50,000 Sodick machines, the EM4 delivers robust, synchronized motion and automation capabilities for advanced CNC, robotics, and industrial automation systems.
