FANUC A20B-2002-0032 Control Board

Overview

The A20B-2002-0032 is a FANUC control board in the A20B-2002 board family. Public industrial listings describe it as a control board, and other board-level parts sources describe it more specifically as a servo drive side panel circuit board.

That places it on the drive-control side of the hardware rather than in the operator-panel or general accessory category.

This board is relevant where the installed machine already depends on the original FANUC servo-drive hardware structure.

In replacement work, boards of this type are selected by exact function and exact board family because the control role is tied to the original machine layout.

Keeping the same board model helps preserve the installed drive-side hardware arrangement.

Technical Data

Application Value

This board is suited to FANUC servo-drive hardware where the installed system already uses the A20B-2002 board family and where the board-level replacement has to follow the original drive-side layout.

Public sources place it in the control-board and servo-drive board category, which makes it relevant to repair, refurbishment, and spare-parts support of installed FANUC systems.

It is also useful in service environments where the objective is to restore the original control section without changing the board family.

Because the published descriptions consistently tie this board to control and servo-drive functions, exact part-number matching is more important than broad series resemblance.

Selection Notes

The key checks are the exact part number, the A20B-2002 family, and the board’s published role as a control board / servo drive side panel circuit board.

These points define whether the replacement matches the installed drive section.

FAQ

Q1: What kind of board is A20B-2002-0032?
It is a FANUC control board. Public parts sources describe it as a control board, and one specialized board listing identifies it as a servo drive side panel circuit board. That means it belongs to the drive-side control hardware of the machine rather than to a general accessory group.

Q2: Is this a CPU board or a drive-related board?
The available public descriptions point to a drive-related board role. The strongest public wording around this model is “servo drive side panel circuit board,” while other parts listings classify it more generally as a control board.

That makes it more appropriate to treat it as a board-level drive/control spare rather than as a main CPU board.

Q3: Why does exact part-number matching matter for this model?
Because control boards are selected by their role inside the original hardware. Public references identify A20B-2002-0032 by exact board code, and that code is the main link to the installed drive section.

Matching the exact number is the safest way to preserve the original board position and control function.

Q4: Where is this board typically used?
It is used in compatible FANUC control hardware where the servo-drive side already depends on this board family.

Public sources place it in the board-level spare-parts category for FANUC systems, which is consistent with repair and replacement of installed machine controls.

Q5: What should be checked before ordering?
Check the installed part number, confirm the machine requires A20B-2002-0032, and verify that the original board role is in the control / servo-drive side panel section of the installed hardware.

Those are the main compatibility points supported by the public descriptions for this model.
