16-axis robot-capable machine controller with EtherCAT motion, 2,560 I/O points, 20 MB program memory, and 3 expansion racks.
Omron NJ501-4310 is a Sysmac NJ5-series machine automation controller configured as an NJ Robotics CPU Unit. It is positioned for coordinated machine control with EtherCAT-based motion and robot control support. Official Omron materials identify it as a 20 MB program-capacity controller with 2 MB retained variable memory and 4 MB non-retained variable memory, supporting 2,560 I/O points, 40 units, up to 3 expansion racks, and 16 motion axes. Omron’s robotics documentation indicates it is intended for robotics applications and supports OMRON G5-series servo drives with built-in EtherCAT communications, plus compatible encoder and SSI input terminals.

Suitable for a packaging line with coordinated robot motion and synchronized servo axes, using EtherCAT to align pick, place, and transport actions.
Eliminates motion-controller fragmentation in compact robot cells that need synchronized control of many axes and I/O points.
Well matched to precision assembly machines requiring coordinated multi-axis trajectories and robot-capable control logic for repetitive part handling.
Provides a single controller for deterministic coordination of motion, handling, and machine sequencing in high-repeatability assembly systems.
Useful in modular production equipment where distributed I/O, servo drives, and encoder feedback must be controlled in a unified architecture.
Reduces cabinet complexity by consolidating motion, robot, encoder, and remote I/O coordination in one controller platform.
