FANUC A20B-8101-0200 Beta i Servo Drive Board

Overview

The A20B-8101-0200 is a drive board in the A20B-8101 family. Listings describe it as PC BOARD / DRIVE BOARD / PCB - BETA I SERVO AMPLIFIER BSVM1, and other parts channels also place it in the Beta iSV control board and servo add-on module category.

That gives the board a clear role in the servo-amplifier section of compatible FANUC hardware rather than in the main-board, display, or communication-board section.

In repair work, a board in this position is matched by exact installed function because the amplifier section depends on the original drive-board structure already used in the machine. Keeping the same model helps preserve the existing servo-amplifier layout and the same board-family continuity inside the control hardware.

Technical Data

Applications

This board is suitable for installed FANUC servo-amplifier hardware where the original system already uses the BSVM1 drive-board structure.

It is especially relevant in amplifier repair, board replacement, and refurbishment where the original servo-control layout must remain unchanged.

Replacement Guidance

Before ordering, confirm the installed board code, verify that the amplifier section uses the same Beta i servo / BSVM1 board position, and check whether the installed system requires a specific firmware or series level.

For a servo drive board, exact functional matching is one of the most important replacement checks.

FAQ

Q1: What kind of board is A20B-8101-0200?
It is a Beta i servo drive board. The most consistent descriptions identify it as a drive board for the Beta i servo amplifier BSVM1, which places it in the amplifier section rather than in the CPU, display, or memory side of the system.

Q2: Why is the BSVM1 description important?
Because that description identifies the board by its installed amplifier role. When a board is tied to a specific servo-amplifier class, the replacement should preserve that same hardware function instead of relying only on family-level similarity.

Q3: Is this a main board?
No. Listings place it in the drive-board / servo-board category, and some describe it as a servo add-on module or control board for the Beta iSV/BSVM1 section.

That means it belongs to the motion-amplifier hardware, not the system motherboard.

Q4: Why does exact model matching matter here?
Because servo drive boards are selected by installed function and amplifier position. A board that looks similar but serves a different amplifier role can create hardware mismatch issues. Matching A20B-8101-0200 helps preserve the original amplifier-side structure.

Q5: What should be checked before buying?
Check the installed part number, confirm the servo section uses the BSVM1 / Beta i board position, and verify whether the system needs a specific firmware or series level.

Those are the main compatibility points shown in service listings for this model.
