Fanuc A16B-2202-0741/04A Servo Amplifier Module

The Fanuc A16B-2202-0741/04A is a servo amplifier PCB module used within Fanuc CNC control systems to drive servo motors with high precision. It is part of the 16-bit system servo control family, typically installed in Fanuc Alpha series or older legacy CNC systems. Technical Specifications: Model Number: A16B-2202-0741/04A Function: Servo Amplifier Control PCB System: Fanuc 16/18/21 series (or earlier, depending on build) Application: Embedded within servo amplifier units for axis control (not a standalone drive) Electrical Characteristics: Input Voltage: Supplied via main servo amplifier chassis (typically 200–230 VAC 3-phase) Control Logic Voltage: 5 VDC (logic level via controller backplane) Output Signal: Pulse-width modulated (PWM) drive to servo transistors Feedback Support: Tachometer or encoder (resolver-type varies by system) Compatibility: Works with matching Fanuc power supply and servo motor amplifier units (e.g., S series) Controlled by CNC CPU via fiber optic or parallel backplane bus Connectors: Multi-pin edge connectors + signal ribbon cables Firmware-dependent: The "/04A" suffix indicates hardware and firmware version matching specific control system revisions Physical: Board Type: Plug-in PCB (mounted inside Fanuc amplifier enclosure) Dimensions: Approx. 280 mm x 120 mm Cooling: Passive convection (dependent on overall amplifier chassis airflow) Use Cases: – CNC lathes, mills, and industrial robotics – Axis control for positioning and speed regulation – Often paired with Fanuc A06B-series motors
