The Omron CJ1W-NC482 is a high-performance EtherCAT-compatible position control unit designed for the SYSMAC CJ1-series programmable logic controllers. This CPU bus unit provides precise 4-axis servo control with support for up to 64 I/O communication nodes and up to 72 total EtherCAT nodes including servo drives. It delivers fast positioning operation with start times as low as 0.15 to 0.4 milliseconds from PLC command to servo operation. The unit supports both memory operation and direct operation via ladder programming, offering a wide range of positioning functions including linear interpolation for up to four axes, circular interpolation, independent positioning, automatic positioning, and continuous positioning. It features a minimum EtherCAT communication cycle of 250 microseconds at 100 Mbps, enabling fast and accurate position control for demanding industrial automation applications.
