Description
📌 FANUC A20B-8200-0360 – Axis/Servo Module PCB (4-Axis)
What it is:
The A20B-8200-0360 is a servo/axis control printed circuit board (PCB) used in FANUC CNC control systems, especially in the Series 0i-C / 0i-MC (Model C) controller family. It’s a 4-axis servo module that plays a key role in managing motion control for multiple axes on the machine.
🔧 Function & Role
-
Axis control board: Handles servo control for up to four axes, coordinating the motion signals sent to the machine’s servo drives.
-
Part of CNC servo system: Often installed alongside the main controller board (e.g., the A20B-8200-039x main PCB) and contributes to actual axis movement processing.
-
On some versions of the 0i-C/0i-MC controller, this board also acts as part of the graphics engine and makes coordinate-related control possible.
📍 Typical Use
-
Used in FANUC Series 0i-C or 0i-MC CNC controllers on machine tools like CNC mills, lathes, machining centers.
-
Critical for machines that require multi-axis motion control (up to 4 axes with this module).
📦 Additional Notes
-
It’s categorized as a servo control/add-on board, not a simple backplane or I/O board.
-
Often found in surplus, refurbished, or repaired conditions when sold through aftermarket suppliers.
