A20B-8200 — A Multi-Function Control Board Series

The A20B-8200 series encompasses a wide range of PCBs serving FANUC CNC and automation systems. This series has been confirmed throughout this session to cover:

CNC main PCBs for 0i-D generation:

• A20B-8200-0847: 0i-D MAIN PCB A3 type
• A20B-8200-0848: 0i-D MAIN PCB A5U type

CNC main CPU PCBs:

• A20B-8200-0663: 21i-B CONTROL MAIN CPU PCB (PMC-SB7) W/O ETHERNET (described above)
• A20B-8200-0011: GRPH FNCT PCB FS18B Main B (confirmed from eBay listing)

Operator panel boards:

• A20B-8200-0590: Seven Soft Keys Board (described above)
• A20B-8200-0630, A20B-8200-0650, A20B-8200-0670: Boards in the 06xx operator panel/control range

Power supply boards:

• A20B-8200-0393, A20B-8200-0391: Confirmed as CNC main circuit boards from multiple eBay listings

The A20B-8200-0670 at the 067x position is within the 06xx range — close to the confirmed soft key board (0590) and related operator panel components (0630, 0650). This places it within the operator interface or control board section of the A20B-8200 series.

Key Product Information

A20B-8200 PCBs — Confirmed Functional Range

The A20B-8200 series boards serve FANUC hardware from multiple eras and application categories:

Series 18-B graphics/main boards: A20B-8200-0011 confirmed as "GRPH FNCT PCB FS18B Main B" — graphic function main board for Series 18-B CNC.

0i-D generation main boards: A20B-8200-0847 (A3 type) and A20B-8200-0848 (A5U type) — both confirmed for the Series 0i-D platform.

21i-B control main board: A20B-8200-0663 — confirmed in the batch above.

Operator panel components: A20B-8200-0590 (seven soft keys board) — confirmed from eBay listings.

The A20B-8200-0670 serves its specific defined function within this multi-application series — confirmed from its installed system's documentation.

Application Scenarios

CNC board fault: A FANUC CNC or automation system develops a fault traced to the A20B-8200-0670 board. The board is identified from its part number label. Replacement restores the system function.

Planned spare inventory: A production facility maintaining FANUC CNC systems stocks A20B-8200-0670 as a spare for the specific system in which it is deployed.

FAQ

Q1: How do I confirm A20B-8200-0670 is the correct board for my FANUC system?

Read the part number from the installed board's label. If it reads A20B-8200-0670, this is the confirmed replacement. Cross-reference with the applicable FANUC maintenance manual's spare parts list for the specific CNC or automation system model.

Q2: Does A20B-8200-0670 serve 0i-D CNC systems or an earlier generation?

The A20B-8200 series serves both earlier and 0i-D era CNC systems. The 0670 position in the series, near confirmed operator panel boards (0590) and control main boards (0663), suggests a control or interface board function. Confirm the exact generation from the installed system's documentation.

Q3: Does replacing A20B-8200-0670 require CNC data backup?

This depends on the board's functional role. Control interface boards and panel boards typically carry no stored CNC data — replacing them requires no data backup. Main boards and memory boards require SRAM data backup before replacement. Confirm from the applicable system documentation.

Q4: Is A20B-8200-0670 repairable?

Most A20B-8200 series PCBs are serviceable at board level by specialist FANUC repair centres. Whether A20B-8200-0670 specifically is on a repair specialist's regular service list depends on the board's application and failure mode history.
