Core Functions

1. Main System Interconnection: Serves as the central backbone connecting all internal NXC100 PCBs (CPU, servo, I/O, etc.).

2. Power Distribution: Distributes regulated 24 VDC power to all plug-in boards.

3. Signal Routing: Routes motion control, safety, I/O, and communication signals between boards and external devices.

4. Mechanical Support: Provides structural mounting and alignment for all internal modules.

5. System Expansion: Enables integration of optional boards (e.g., additional I/O, network interfaces).

Application

• Primary Use: Yaskawa Motoman NXC100 series robot controllers.

• Key Industries: Semiconductor wafer handling, LCD/FPD manufacturing, and high-precision automation cells.

• Compatibility: Not interchangeable with other Yaskawa controller families (XRC, DX100, YRC1000).

Maintenance Notes

• ESD Critical: Always use anti-static gloves and mats when handling.

• Connector Inspection: Periodically clean and check all edge connectors and slots for wear or contamination.

• Replacement: Use only original Yaskawa F352774-1 / JANCD-NBB31-E to ensure signal integrity and mechanical fit.
