Description
📌 FANUC A20B-3300-0243 — 2-Axis High-Speed Servo Module
Description:
The FANUC A20B-3300-0243 is a servo control module used in modular FANUC CNC control systems. It provides control for two axes in the machine’s motion/servo subsystem, enabling precise, high-speed coordination of those axes as part of the CNC’s motion control architecture.
Key Details:
-
🎯 Function: High-speed 2-axis servo control module — handles motion control for two servo axes within the CNC.
-
🛠️ Series: Part of the A20B-3300 series of modular control PCBs used in FANUC i-Series CNC controllers (e.g., Series 16i, 18i, 21i).
-
🔌 Application: Installed on the controller’s backplane/rack alongside other modules such as CPU cards, memory, display, and I/O modules. It works with the main control logic to interpret motion commands and drive servo positioning for two axes.
-
📍 Typical Usage: Used in systems requiring dedicated motion control for two axes, such as in 2-axis or multi-axis CNC machines where additional axis modules are added modularly.
How It Fits in the System:
In modular FANUC CNC architectures:
-
The CPU module provides overall control logic and G-code interpretation.
-
Servo modules like the A20B-3300-0243 execute motion commands on specific axes.
-
Multiple servo modules can be used in one system to control more axes (e.g., 4-axis, 6-axis modules).
