The Fanuc A20B-2900-031 Servo Amplifier Interface Module is a Fanuc original interface component designed to connect servo amplifiers to the control system in CNC and robotics installations. It facilitates the transmission of motion commands and feedback signals between the main controller and attached servo amplifiers, enabling coordinated, precise motion. As the A20B-2900-031 part, it is used as a replacement or spare in compatible Fanuc systems requiring a servo amplifier interface module.
