The Yaskawa Motoman NX100 controller revolutionized robot control with its ability to manage up to four robots (36 axes) from a single CPU. Although succeeded by the DX and YRC series, the NX100 remains a workhorse in many automotive and metal fabrication plants.
This NX100 Spare Parts Index is a structured reference to help maintenance teams identify critical JZNC and JANCD components, from the Windows CE-based programming pendant to high-performance servo packs.
1. NX100 System Identification
The NX100 system is easily recognized by its silver/grey cabinet and the NX100 Programming Pendant (NPP) featuring a large color LCD and Windows CE interface.
- Controller Generation: Successor to XRC; Predecessor to DX100.
- Common Robot Models: EA1400, EA1900, HP6, HP20, UP20, UP50.
- Core Technology: PC-architecture with Sigma III servo technology.
2. NX100 Programming Pendant (NPP) & Cables
The NX100 pendant was a major leap forward, offering a more intuitive GUI and lighter weight than previous generations.
| Component Name | Part Number / Type | Function |
|---|---|---|
| NX100 Programming Pendant | JZRCR-NPP01-1 | The primary handheld interface (Windows CE). |
| Pendant Connection Cable | JZNC-N660-2005-T506 | Available in 7m, 10m, and 15m lengths. |
| LCD Replacement Kit | NPP LCD Assembly | High-brightness 5.7-inch color display. |
| NPP Protective Cover | Bumper Kit | Silicon-based protection against drops. |

3. CPU Rack & Control Boards (JANCD/JZNC)
The NX100 uses a modular board system. Failures here usually result in "Communication Error" or "System Boot" alarms.
| Component Name | Part Number / Type | Function |
|---|---|---|
| Main CPU Board | JZNC-NRK01 | The core processor module. |
| Robot Control Board | JANCD-NTU01 / NTU02 | Handles robot motion calculation. |
| Safety/Interface Board | JANCD-NIF01 | Handles E-Stop and external I/O. |
| Power Supply Unit (PSU) | JZNC-NPS01 | Provides DC power to the CPU rack. |
| Expansion I/O Board | JANCD-NIO01 / NIO02 | Digital input/output modules. |
4. Servo Packs & Motion Control (Sigma III)
NX100 utilizes the Sigma III series amplifiers. These units are often multi-axis modules to save cabinet space.
| Component Name | Part Number / Type | Function |
|---|---|---|
| Servo Amplifier Module | JZRCR-NUAxx (e.g., NUA01) | Axis control amplifiers. |
| Rectifier Module | JZRCR-NTV01 | Converts AC to DC for servo packs. |
| Converter Unit | JZRCR-NCT01 | Signal conversion. |
| Brake Release Unit | Brake Release Module | Safely moving the robot without power. |
5. NX100 Maintenance & Troubleshooting FAQ
Q: My NX100 pendant is stuck on the "Windows CE" boot screen. What should I do?
A: This often indicates a corrupted CF (Compact Flash) card on the CPU or a failure in the JZNC-NRK01 board. We recommend keeping a verified "CMOS" backup and a spare CF card pre-loaded with your system parameters.
Q: Can I use an NX100 pendant on an older XRC controller?
A: No. While they look somewhat similar, the communication protocols and hardware architecture (Windows CE vs. proprietary) are incompatible.
Q: How often should I replace the encoder batteries?
A: Yaskawa recommends replacing the encoder backup batteries every 12 months. If the "Encoder Battery Low" alarm appears, do not turn off the power until the batteries are replaced, or you will lose the robot's home positions (Original Data).
6. Sourcing Obsolete NX100 Spares
As the NX100 ages, many original boards and servo packs are no longer in production by Yaskawa. inrobots.shop provides:
- Refurbished JZNC/JANCD Boards: Fully tested on our internal NX100 test rigs.
- Sigma III Drive Repairs: Expert repair and exchange for NUA and NTV modules.
- Pendant Repair Services: Replacing joysticks, screens, and keypad membranes for the JZRCR-NPP01-1.
