Product Overview
The Omron NJ501-1300 is a Sysmac NJ5-series machine automation controller CPU, manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
It runs motion control, sequence control, and an OPC-UA server from a single program. The built-in EtherCAT master handles up to 16 servo axes (192 total EtherCAT nodes). The built-in EtherNet/IP port connects to HMIs and remote I/O. Primary task cycle time is 0.5 ms, with 20 MB of program and 6 MB of variable memory.
Programming is in Sysmac Studio (IEC 61131-3 plus CFC and structured text). The unit is 90 x 96 x 150 mm, 550 g. The NJ501-1500 sibling adds CIP-Safety (SL3); the NJ501-1400 is the 16-axis variant with safety; the NJ301-1200 is a smaller 4-axis NJ3 CPU. The NJ101-1000 is the entry NJ1-series 2-axis controller.
Key Features

- Built-in EtherCAT master handles up to 16 servo axes (192 total nodes) for Accurax G5 / 1S servo drives
- Built-in EtherNet/IP port, OPC-UA server, USB Type-B slave for Sysmac Studio programming, SD card slot for project transfer
- Up to 40 NX-series I/O units on the local rack, 90 x 96 x 150 mm DIN-rail body, 550 g, CE / cULus / KC listed
- SKU: NJ501-1300
- Series: Omron Sysmac NJ5-series machine automation controller (NJ501 family)
- I/O: 40 I/O
Best-Fit Applications
- Motion controller on a 16-axis carton-packing line running 1S servo drives over EtherCAT and reporting to a NA5 HMI
- Mid-volume machine-build where the NJ5 replaces a CJ2H plus EtherCAT slave module and consolidates into one Sysmac Studio project
- Spare replacement on an automotive assembly cell where the existing NJ501-1300 fails and the project loads directly from SD card
Buying Checklist
- Pick the NJ501-1300 for a Sysmac NJ5 CPU with 20 MB memory, 16 EtherCAT axes, and EtherNet/IP, with no safety.
- Pick the NJ501-1500 instead when the cell needs CIP-Safety (SL3) integrated safety on top of the same 16-axis EtherCAT.
- Pick the NJ301-1200 instead when the application only needs 4 axes of motion and a smaller NJ3 CPU on the same Sysmac Studio platform.

FAQ for NJ501-1300
What is the Omron NJ501-1300 used for?
It is the Sysmac NJ5-series machine automation controller with 20 MB program memory, a built-in EtherCAT master for up to 16 servo axes, a built-in EtherNet/IP port, and an OPC-UA server. It replaces a separate PLC + motion controller + network gateway pair and runs everything from a single Sysmac Studio project.
NJ501-1300 vs NJ501-1500 - what is the difference?
Both are NJ5 CPUs with 20 MB memory, 16 EtherCAT axes, and EtherNet/IP. The 1300 is the basic NJ5; the 1500 adds CIP-Safety (SL3) for integrated safety over the same EtherCAT port. Pick the 1300 for non-safety machines; pick the 1500 when the cabinet needs integrated safety without adding a separate safety controller.
What software does the NJ501-1300 run?
Sysmac Studio version 1.0 or later. The package supports IEC 61131-3 languages (ladder, structured text, function block), CFC, and the Sysmac motion toolkit for configuring 1S / G5 servo drives and Accurax inverters. Project files transfer over USB or SD card.
Can the NJ501-1300 connect to a CJ-series I/O rack?
Yes, with a CJ1W-IC101 I/O control unit on the option-board slot. The IC101 maps a CJ-series expansion rack onto the NJ5's I/O table, so existing CJ1W special I/O modules and CJ1W basic I/O can stay in the cabinet during a migration.
How many EtherCAT nodes can the NJ501-1300 address?
Up to 192 EtherCAT nodes in total, with a firm cap of 16 synchronous servo axes. The remaining 176 are typically distributed NX-IO slaves, I/O terminals, and 1S servo drives running in non-synchronous mode. The number of physical nodes is also limited by the cycle time and the node count of each slave.
