FANUC A860--T341 Pulsecoder For AC Servo Motors

The FANUC A860--T341 Pulsecoder AIAR128 is an encoder feedback device designed for AC servo motors, transforming rotation into precise pulse signals that the servo drive uses to determine position and speed. This unit is identified by FANUC part number 305309, aiding inventory management, repair documentation, and replacement tracking within FANUC automation systems. The AIAR128 designation places it within FANUC's pulsecoder family, a component designed to deliver feedback for closed-loop motor control. As a dedicated pulsecoder module, it supports AC servo motor installations that rely on accurate encoder feedback for steady speed regulation and precise positioning. This description reflects use as a replacement or maintenance part in existing FANUC installations requiring the A860--T341 pulsecoder solution.
