General Description

Basic Information

• Model: JANCD-NBB31B

• Manufacturer: Yaskawa Electric / Motoman Robotics

• Type: Controller backplane / system baseboard

• Compatible Controller: NXC100 series robot controller

• Revision: Rev D (final production revision)

• Manufacturing Part Number: F352077-1

• Weight: approx. 1.5 kg

• Status: Discontinued (spare parts only)

Technical Specifications

• Power Distribution: Routes 24 VDC and internal bus voltages to all slots; includes overvoltage and overcurrent protection.

• Slot Configuration: Provides multiple high‑speed card edge connectors for CPU, I/O, servo, and communication boards.

• Signal Integrity: Enhanced ground plane design, controlled impedance traces, and EMI shielding to reduce noise and crosstalk.

• Operating Temperature: 0 °C to +45 °C (industrial standard).

• PCB Material: FR‑4 with gold‑plated contacts for reliability and oxidation resistance.

• Construction: Reinforced mounting points to withstand vibration in factory environments.

Key Functions

1. System Interconnection: Acts as the main backbone connecting the CPU, digital/analog I/O, network modules, and servo drives inside the NXC100 controller.

2. Power Routing: Distributes stable, filtered power to all plug‑in boards, protecting against voltage spikes and fluctuations.

3. Signal & Communication Bus: Transfers high‑speed control signals, safety interlocks, and network data between internal modules and external devices.

4. Mechanical Support: Secures and aligns all controller cards, ensuring structural stability during vibration or thermal cycling.

Compatibility & Applications

• Primary Use: Yaskawa NXC100 robot controller (for industrial robots, automation cells, and semiconductor equipment).

• Not Compatible With: YRC1000, DX, FS series controllers or non‑Yaskawa systems.

• Drop‑in Replacement: Directly replaces JANCD-NBB30 / NBB30B in existing NXC100 cabinets.

Installation & Safety Notes

• Power Off First: Disconnect main power and wait for capacitors to discharge before installation/removal.

• ESD Protection: Always use a grounded anti‑static wristband to avoid static damage to sensitive components.

• Slot Alignment: Insert boards carefully into backplane connectors; do not force or bend pins.

• Cable Separation: Route signal cables away from high‑voltage power cables to minimize EMI.

• Qualified Personnel: Installation and maintenance must be performed by certified technicians.
