• Function:

  • System backplane / motherboard

  • Interconnection for CPU, I/O, servo, and communication boards

  • Power distribution and signal routing

• Revision: DF9203004‑C0（标准版本）

2. Specifications

2.1 Electrical

• Supply Voltage: 24 VDC ±10%

• Backplane Slots: 10（比 XBB01 多 2 槽）

• Signal Interface: Parallel bus + power rails

• Isolation: Enhanced opto‑isolation on I/O lines

2.2 Physical

• Humidity: 5%–80% RH (non‑condensing)

• Vibration: ≤ 0.5 G (10–500 Hz)

3. Board Outline & Slots

• Slot 0: CPU/Main Control Board (JANCD‑XCP series)

• Slot 1–8: General‑purpose I/O/Servo Boards (e.g., JANCD‑X1002, XEW01)

• CN1: 24 VDC Power Input

• CN2: System Bus / Signal Interface

• CN3: External I/O Terminal (DB or flat cable)

4. LED Indicators

• PWR (Green): ON = 24 VDC normal

• SYS (Green): Blinking = system bus active

• ALM (Red): ON = short circuit / overcurrent / board not seated

5. Installation & Replacement

1. Power OFF the controller; wait 5 minutes for capacitor discharge.

2. Use an anti‑static wristband.

3. Remove old backplane: Disconnect all cables → remove mounting screws → take out board.

4. Install new backplane: Align and insert → tighten M3 screws (0.8–1.0 N·m) → reconnect all cables.

5. Power ON and verify: PWR ON, SYS blinking, ALM OFF.

6. Compatibility

• Controller: XRC standard / extended cabinet

• Compatible Boards: JANCD‑X series (X1002, XEW01, XTU01, etc.)

• Replacement: Direct replacement for JANCD‑XBB01

7. Maintenance & Troubleshooting

7.1 Maintenance

• Quarterly: Check gold‑plated contacts for oxidation; verify connector tightness.

• Annually: Clean dust with low‑pressure air; inspect solder joints and connectors.

7.2 Troubleshooting

• PWR OFF: Check 24 VDC input at CN1 and fuse.

• ALM ON: Check for incorrect board insertion, short circuit, or dirty contacts.

• SYS not blinking: Re‑seat CPU and backplane; check bus connections.

8. Ordering Information

• Part Number: JANCD-XBB02 (DF9203004‑C0)

• Manufacturer: Yaskawa Electric Corporation

• Warranty: 12 months under normal operating conditions

9. Warnings

• For qualified personnel only.

• Disconnect power before servicing; wait for discharge to avoid electric shock.

• Do not modify the board; avoid touching gold‑plated contacts to prevent oxidation.
