Description
📌 FANUC A20B-3300-0032 — 4-Axis Servo / Axis Control Module (FSSB)
Description:
The FANUC A20B-3300-0032 is a servo/axis control printed circuit board (PCB) used in FANUC CNC контроллери, particularly in the i-Series modular controller families (such as Series 16i, 18i, 20i, 21i). It’s designed to provide motion control functionality for up to four axes in machine applications and is often referred to as a 4-Axis FSSB servo module.
Key Functions & Features:
-
🛠️ 4-Axis Motion Control: Handles control and coordination of up to four servo axes in the CNC system.
-
📡 FSSB Interface: Connects to the controller via FANUC Servo Serial Bus (FSSB) for high-speed servo data transfer.
-
🤖 Modular Design: Works as a plug-in module alongside other essential boards (CPU, memory, display, I/O interfaces) in the CNC electronics rack.
-
📍 Application: Commonly found in FANUC Series 16i/18i/20i/21i i-Series controllers, where dedicated axis-control modules are used instead of all-in-one mainboards.
