64-axis machine controller CPU with EtherNet/IP, EtherCAT, 20 MB program memory, and 2,560-point I/O capacity.
Sysmac NJ501 Machine Automation Controller CPU unit with built-in EtherNet/IP and EtherCAT, designed as the flagship NJ5 controller platform. Manufacturer and catalog pages identify the NJ501-1500 as a 64-axis CPU with 20 MB program capacity, 2 MB retained variable memory, and 4 MB non-retained variable memory. The NJ-series catalog also lists 2,560 I/O points / 40 units (3 expansion racks) for the NJ501 CPU family. Official Omron product pages describe the platform as a high-performance machine controller for motion, robotics, database connectivity options, and harsh industrial environments.

Coordinates many synchronized servo axes in a single controller for complex packaging lines with multi-axis motion and line synchronization.
Eliminates controller fragmentation in machines requiring up to 64 coordinated axes.
Serves as the central CPU for assembly cells that need deterministic motion, discrete I/O, and robot-adjacent machine coordination.
Provides one control platform for motion, I/O, and cell-level sequencing in dense automation cells.
Fits modular production equipment that needs high I/O density and distributed expansion across multiple racks while keeping one CPU core.
Supports scalable machine architectures without splitting logic across multiple controllers.
