Fanuc A16B-2202-0661/04A Servo Amplifier Module

The Fanuc A16B-2202-0661/04A is a servo amplifier control PCB designed for use within Fanuc's servo drive systems. It acts as a critical control interface between the CNC system and the servo power stage, handling tasks such as feedback processing, PWM control, and communication with the CNC controller. General Description Part number: A16B-2202-0661/04A Type: Servo amplifier control board (PCB) System: Fanuc CNC (typically Alpha Series or related analog drive series) Mounting: Installed in Fanuc servo amplifier housing (not standalone) Revision: /04A (hardware version 4A) Electrical Specifications Power supply: Receives low-voltage power from the main amplifier Signal interfaces: – Encoder/resolver feedback (via motor feedback lines) – PWM or analog command signals (from CNC controller) – Tachometer input or velocity feedback (model dependent) Motor control: For brushless AC servo motors Control loops: Current loop, velocity loop, and position interface logic Connectors: Fanuc-specific ribbon and terminal connectors for amplifier integration Functions Processes servo feedback and converts it into motion control signals Sends drive commands to the IGBT or power transistor section Provides fault detection and alarm signaling to CNC system Interfaces with Fanuc CNC via serial or parallel communication bus Enables accurate positioning and dynamic torque control Please review pictures carefully and let us know if you have any questions!
