x📌 FANUC A20B‑3300‑0242 — 4‑Axis High‑Speed Servo / Axis Control Module
Description:
The FANUC A20B‑3300‑0242 is a servo/axis control printed circuit board (PCB) used in FANUC CNC controllers to handle motion control for up to four axes via a high‑speed servo interface. It is part of the modular A20B‑3300 series of control modules.
Key Features & Function:
-
🔧 4‑Axis Servo Control Module: Designed to control and coordinate four axes of motion on compatible FANUC CNC systems.
-
🏎️ High‑Speed FSSB Interface: Uses FANUC’s FSSB (Fanuc Servo Serial Bus) communication protocol for fast, real‑time exchange of servo position and command data between the module and the main CPU.
-
🛠️ Modular Plug‑In Board: Fits into the control backplane alongside other control boards (CPU, memory, display, etc.) in controllers that employ a modular architecture.
-
📌 Applications: Typically used in FANUC i‑Series “B” generation controllers including 15i‑B, 16i‑B, 18i‑B, 21i‑B and similar series where modular axis control cards are present.
-
🔁 Replacement Info: This part has been discontinued by FANUC and may be replaced by successor modules like A20B‑3300‑0392 in newer or updated versions.
Typical Use Case:
Installed within the CNC’s control electronics rack, this board interprets motion commands from the controller’s CPU and translates them into precise control for four axes, enabling synchronized, real‑time motion in multi‑axis machines.
