3. Board Configuration & Slot Assignment

1. CPU Slot: JANCD-YCPxx series (YCP01-E/YCP02-E)

2. Safety Slot: JANCD-YSF21-E / YSF22-E (dual-safety compatible)

3. Servo Interface Slot: JANCD-YIF01-4E / YIF02-4E

   4–7. I/O Expansion Slots: JANCD-YIO21-E, JANCD-Y1021, YEW01-E (welding), YBK01-2E (brake)

   8–9. Optional Slots: For communication boards (e.g., Ethernet/DeviceNet)

   10–12. Reserved Slots: For future expansion

• CN1–CN4: DC24V power distribution (isolated for servo/I/O)

• CN5–CN7: System bus communication (high-speed differential signals)

• CN8: Cabinet ground terminal (heavy-duty, low-resistance)

• CN9: External emergency stop pass-through

4. Safety Precautions

• Disconnect main power before installation, removal, or handling.

• Wait 15+ minutes after power-off for capacitor discharge—risk of electric shock.

• Never insert/remove boards while powered; causes permanent damage and fire hazard.

• Ensure proper grounding of backplane and cabinet to prevent ESD damage and noise.

• Do not expose to water, oil mist, dust, or direct sunlight.

• Replace only with JANCD-YBB02 (YBB01 is not pin-compatible for all slots).

• Do not bend, drop, or over-tighten mounting screws—PCB cracking risk.

• Clean only with a dry lint-free cloth; no liquid cleaners.

5. Installation Procedure

1. Power OFF: Turn off controller main power; wait 15 minutes.

2. Cabinet Access: Open front door; locate backplane mounting rack.

3. Mounting: Align YBB02 with 4 mounting holes (2 top/2 bottom); secure with screws (0.8–1.0 N·m torque).

4. Board Insertion:

   • Insert CPU board into Slot 1 until fully seated (latch clicks).

   • Insert safety, servo interface, and I/O boards into assigned slots.

   • Verify all boards are fully locked (no loose connectors).

5. Wiring: Connect DC24V power cables to CN1–CN4; ground wire to CN8.

6. Close Cabinet: Secure door; restore main power.

7. Verification: Check system LED indicators; confirm no boot errors.

6. Replacement Instructions

1. Backup Data: Save all programs, parameters, and system data via teach pendant or CF card.

2. Power OFF: Disconnect main power; wait 15 minutes.

3. Remove Boards: Unplug and remove all boards from old backplane.

4. Remove Old Backplane: Unscrew 4 mounting screws; lift carefully (avoid snagging wires).

5. Install New Backplane: Follow Section 5 steps 3–5.

6. Reinstall Boards: Insert boards in correct slot order; ensure full seating.

7. Restore Data: Power on; restore backed-up data.

8. System Test: Perform full axis check, I/O test, and safety circuit verification.

7. Troubleshooting

No Power to Backplane

• Check main power ON status.

• Verify DC24V PSU output (24V ±10%).

• Inspect CN1–CN4 cables for looseness/damage.

• Check on-board fuse (if equipped) for continuity.

Boot Failure After Replacement

• Confirm all boards are fully inserted and locked.

• Inspect edge connectors for bent pins, dirt, or oxidation.

• Verify correct slot assignment (CPU in Slot 1, etc.).

• Reinstall or restore system firmware/data.

Communication Errors

• Clean edge connectors with contact cleaner (if dirty).

• Check for loose board insertion or damaged connectors.

• Verify CN8 ground connection (low resistance <0.1Ω).

• Reduce cabinet noise (check fan/EMI sources).

Overheating Alarms

• Ensure cabinet fans are operational; vents unblocked.

• Check for dust buildup on PCB surface and connectors.

• Verify no boards are short-circuited or drawing excess current.

8. Maintenance

• 6-Month Inspection: Check mounting screw torque, connector tightness, and dust accumulation.

• Cleaning: Use dry lint-free cloth to remove dust; avoid touching gold connectors.

• Connector Care: Inspect for oxidation; clean with contact cleaner if needed.

• Replacement Life: 5–8 years (or immediately if burned, corroded, or damaged).

9. Compatibility Notes

• Fully Compatible: DX100/DX200 with standard I/O configuration.

• Not Compatible: YBB01 cannot replace YBB02 (slot count/pinout differences).

• Upgrade Path: YBB02 can replace YBB01 in DX100/DX200 cabinets (requires reconfiguration of I/O slots).
