INDRAMAT 109-0780-4B01-02 (NR 312)

The INDRAMAT 109-0780-4B01-02 (NR 312) is an industrial Hall/Tachogenerator feedback board (PCB) used in Indramat servo drive systems to process and condition Hall sensor and tacho signals from motor feedback units. This board converts raw commutation and speed data into reliable feedback for the drive controller, enabling precise motor control in applications such as CNC machines, robotics and automated production equipment. Built for rugged industrial environments, it ensures stable signal integrity under vibration, temperature variations and continuous operation. Ideal for OEM systems, retrofit upgrades or maintenance replacements, the 109-0780-4B01-02 helps restore accurate motor feedback and improve overall drive performance.
