Product Overview
The NX102-1000 sits in the middle of Omron's NX102 lineup — a step up from the NX102-9000 (no EtherCAT) and a tier below the NX102-1100/1200 (higher axis counts and program memory). The 1000 suffix is the model code for the standard variant: 5MB program memory, 33.5MB variables, 2 synchronous axes via the built-in EtherCAT master, 4 PTP axes, and 15 total axes including virtual. In a typical machine, the NX102-1000 acts as the main controller for packaging, material handling, and assembly cells that need deterministic motion but don't justify the larger NJ5 series. Two built-in EtherNet/IP ports (up to 64 connections) and two EtherCAT ports (100 Mbps) cover the network side, with OPC-UA server built in for MES/ERP integration. On the wiring side, the unit takes 24 VDC on the power supply terminal and draws 5.80 W max. The 72 × 100 × 90 mm footprint and 390 g weight make it one of the smallest EtherCAT-master controllers in the NX family. Up to 32 local NX I/O units can be mounted directly on the right side, with expansion to remote EtherCAT slaves as needed. The most common first-time-install gotcha is the NX Bus I/O configuration mismatch: if the hardware layout in Sysmac Studio doesn't match what's physically mounted, the unit throws error 0x85540000 ("NX Bus I/O Communication stopped") and refuses to go RUN. Synchronise the configuration with the physical rack before commissioning, or the controller will not start. Compared to the CJ2M-CPU33 (the previous-generation mid-range), the NX102-1000 adds native EtherCAT, built-in motion primitives, and removes the need for a separate EtherCAT slave unit. Compared to the NJ501-1300 (the flagship), the NX102-1000 is smaller, cheaper, and has lower axis capacity — but for most 2–4 axis machines it's the right fit.

Best-Fit Applications
- Synchronising sealing and cutting stations on horizontal-form-fill-seal packaging machines
- Coordinating 2-axis delta robots on food-grade pick-and-place cells with EtherCAT drives
- Running 4-axis SCARA arms in electronics assembly with vision-triggered corrections
- Replacing legacy CJ2M + pulse-output modules with native EtherCAT motion in retrofit projects
Buying Checklist
- Compact 72 mm width fits where NJ5 series can't, while keeping 15-axis motion capacity
- Native EtherCAT master removes the need for a separate CJ1W-ECT21 slave unit
- 5MB program memory and 33.5MB variables handle most mid-range machine programs without upgrade
- No-battery design reduces maintenance — no scheduled battery swaps like CJ1/NJ5
- OPC-UA server built in, no additional software required for MES data exchange

FAQ for NX102-1000
What's the difference between NX102-1000 and NX102-1100?
The 1000 has 5MB program memory and 2 synchronous axes; the 1100 has 10MB and 4 synchronous axes. For machines that don't need 4+ synchronised axes, the 1000 is the right pick. The 1100 is for larger or more complex machines with more EtherCAT slaves.
How many axes can the NX102-1000 control in total?
2 synchronous axes (motion engines running in lockstep) + 4 PTP axes (point-to-point, independently commanded) + virtual axes, for 15 total. PTP and synchronous axes can coexist — for example, 1 synchronous group of 2 axes plus 4 standalone PTP axes uses 6 of the 15.
Can the NX102-1000 work with existing CJ1 I/O over EtherCAT?
Indirectly, yes — via a CJ1W-ECT21 EtherCAT slave unit on the CJ1 rack. The NX102-1000 talks EtherCAT to the ECT21, and the ECT21 exposes the CJ1 I/O bus. Migration projects typically keep CJ1 I/O for cost reasons and replace the CPU with NX102 over a planned retrofit window.
How do I troubleshoot ERR/ALM on the NX102-1000?
Most ERR/ALM states stop the program and clear all outputs. Connect via USB or Ethernet, open Sysmac Studio, and read the error from the Controller Event Log. The most common error is 0x85540000 (NX Bus I/O config mismatch) — fix the unit layout in the project, transfer to controller, and cycle power. Other common errors are 0x04500001 (CPU error) and 0x84D00000 (motion periodic task overflow).
