x📌 FANUC A20B-3300-0033 — 2-Axis Servo / Axis Control Module
Description:
The FANUC A20B-3300-0033 is a servo/axis control printed circuit board (PCB) used in FANUC modular CNC controllers (such as the 16i, 18i and 21i i-Series controls). It is part of the A20B-3300 product family of control modules and serves as a 2-axis control card handling motion control for up to two servo axes.
Key Features & Function:
-
🎯 2-Axis Control: Provides control for two servo axes — coordinating motion commands from the CNC system to the servo drives.
-
🔄 FSSB Interface: Uses FANUC’s FSSB (Fanuc Servo Serial Bus) communication protocol to interface with the master control board and other modules. This high-speed serial bus helps relay real-time servo positioning and command data.
-
🧩 Modular Design: Designed as a plug-in board that installs into the modular control rack of compatible FANUC CNC controllers (commonly Series 16i/18i/21i).
-
🤖 Servo Function: Processes position/velocity control for two axes — essential for precise motion control in multi-axis machining tasks.
Typical Usage:
This board is installed alongside other CNC modules — including the CPU board, memory modules, display/graphics boards, and I/O interfaces — to form a complete control system. In a typical setup:
-
The main CPU sends motion commands to the servo modules.
-
The A20B-3300-0033 interprets and translates those commands into control signals for two axes.
-
Feedback from the servo amplifiers/encoders helps the CNC maintain accurate position and velocity control.
Common Applications:
-
FANUC Series 16i/18i/21i modular CNC controllers.
-
Industrial machine tools requiring dual-axis servo control (e.g., certain milling or turning configurations).
