The KNC-SRV-FD423-EA-000 EtherCAT Servo Drive is an open network based on Ethernet to achieve real time control. It is capable of supporting very high speeds and synchronized control. The EtherCAT drive is best suited for establishing protocol in motion control and factory automation applications. With this technology the process of receiving Ethernet data, decoding the data, and then copying the process data to different devices, is not needed. The EtherCAT slave device can read the data marked with the devices address information when the frame passes this device. Data reading and data writing could be done within several nanoseconds.
