The Omron CJ1W-NCF71 is a motion control module for the CJ Series PLC platform, handling up to 16 axes of servo or stepper control. The module accepts a USB connection for setup and monitoring—no serial port on the face, so a USB cable is the expected link to CX-Motion or Sysmac Studio.
What the 16-axis rating means for selection
A 16-axis controller means this module can independently coordinate motion on up to 16 servo or stepper axes without burdening the CPU rack with pulsed output modules or separate motion cards. Each axis is managed via a dedicated pulse train or analogue command from the CJ1W-NCF71, so it replaces a stack of position controllers for multi-axis machinery—assembly stations, packaging cut-offs, or gantry pick-and-place that need synchronized moves.
CE, cULus, and C-tick marks cover the module for use in CE-marked EU machinery, UL-compliant North American panels, and Australian installations. No RoHS or REACH certificate appears in this listing, but those are typically included in the shipment documentation for current-production Omron parts.
