Product Overview
The Omron NJ501-1400 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. Specifications on this page were checked against Omron's NJ-series Robot Controller documentation.
It runs motion control, sequence control, and an OPC-UA server from a single program. The built-in EtherCAT master handles up to 32 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 NJ501-1300 sibling is the 16-axis version on the same body; the NJ501-1420 adds database connectivity (SQL client); the NJ501-1500 is the 64-axis version. The NJ301-1200 is the smaller 4-axis NJ3 CPU.
Key Features
- Sysmac NJ5-series machine automation controller, 20 MB program memory, 6 MB variable memory, 0.5 ms primary task cycle
- Built-in EtherCAT master handles up to 32 synchronous 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 CJ-series expansion units (3 expansion racks, 2,560 I/O points) on the CJ I/O Bus; NX-series units require an NX-EIC/NX-EIC2 coupler plus CJ-series expansion units on the CJ I/O Bus, 90 x 96 x 150 mm DIN-rail body, 550 g
- SKU: NJ501-1400
- Series: Omron Sysmac NJ5-series machine automation controller (NJ501 family)
- I/O: 2560 points
Best-Fit Applications
- Motion controller on a 32-axis cartoning line running 1S servo drives over EtherCAT and reporting to a NA5 HMI
- Multi-station assembly cell where the NJ5 replaces a CJ2H plus a separate motion controller and consolidates into one Sysmac Studio project
- Spare replacement on a packaging line where the existing NJ501-1400 fails and the project loads directly from SD card to the new CPU
Buying Checklist
- Pick the NJ501-1400 for a Sysmac NJ5 CPU with 20 MB memory, 32 EtherCAT axes, and EtherNet/IP, with no safety.
- Pick the NJ501-1300 instead when the cabinet only needs 16 EtherCAT axes on the same Sysmac NJ5 platform.
- Pick the NJ501-1500 instead when the cell needs CIP-Safety (SL3) integrated safety on top of 64 EtherCAT axes on the same NJ5 body.

FAQ for NJ501-1400
What is the Omron NJ501-1400 used for?
It is the Sysmac NJ5-series machine automation controller with 20 MB program memory, a built-in EtherCAT master for up to 32 servo axes, a built-in EtherNet/IP port, and an OPC-UA server. It is the 32-axis non-safety step up from the NJ501-1300 and replaces a separate PLC + motion controller + network gateway pair with a single Sysmac Studio project.
NJ501-1400 vs NJ501-1300 - what is the difference?
Both are NJ5 CPUs with 20 MB memory, EtherCAT, EtherNet/IP, and OPC-UA. The 1400 addresses up to 32 synchronous servo axes; the 1300 is the 16-axis version. Pick the 1400 when the machine needs more than 16 axes; pick the 1300 for the typical 16-axis packaging cell on the same Sysmac Studio project.
Does the NJ501-1400 have built-in safety?
No. The NJ501-1400 is the non-safety 32-axis variant. For CIP-Safety (SL3) on the same NJ5 body, pick the NJ501-1500 (64 axes + safety) or add a separate NX-SL5500 safety CPU and an NX-CSG320 communication unit. The NJ501-1300, NJ501-1400, and NJ501-1500 all share the same 20 MB program memory.
What software does the NJ501-1400 run?
Sysmac Studio version 1.0 or later. The package supports IEC 61131-3 languages (ladder, structured text, function block), CFC, and the Syscam motion toolkit for configuring 1S / G5 servo drives and Accurax inverters. Project files transfer over USB or SD card. The OPC-UA server exposes variables to MES and SCADA clients.
Can the NJ501-1400 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 I/O table, so existing CJ1W special I/O modules and CJ1W basic I/O stay in the cabinet during a migration. Up to 40 CJ expansion units on 3 racks.
