The Omron NX502-1500 is an NX-series machine automation controller designed to scale a single machine up to complete line control, with the NX Local Bus as its slice-expansion path and EtherCAT plus 2× EtherNet/IP ports built in for motion and cell networking. It mounts on DIN rail, programs over Ethernet in ladder, structured text or function block, and uses an SD-card flash port for recipe and project handover in the field.
Headline ratings and what they govern
Local I/O capacity is rated at 1024 points, expandable to 8960 points with an NX Coupler; up to 63 NX units attach locally. Minimum cycle time is 0.25 ms, which is the figure that places the NX502-1500 in continuous high-speed motion duty on EtherCAT rather than slower scan-and-log applications; sized against this, the unit is not the right slot for slow process loops where a smaller NX CPU would do the job. Motion is rated for 64 total axes with 64 coordinated and no dedicated point-to-point axes, which confirms the controller class as a multi-axis coordinated motion platform rather than a point-to-point indexer. Program capacity is 80 MB with 256 MB of non-retained data, sized for cell-level recipes and multi-machine sequencing without offloading to external storage on a routine basis.
Where this class of controller is used
NX-series machine automation controllers sit in the Omron PLC and controller family and are specified into packaging lines, material-handling cells and discrete machine builds where EtherCAT motion and EtherNet/IP plant integration are required on the same CPU.
Sourcing reality
Lifecycle status is recorded as current on the seed listing, so the NX502-1500 remains a live production line and the quoteable posture is specified-into-the-BOM against an RFQ rather than last-time-buy — quote the part number with quantity and required delivery window and it will be priced off the active channel.
