The Bosch Rexroth Indramat TDA 1.3-050-3-A0I controller belongs to the prestigious TDA Main Spindle Controllers series and is designed for high-performance digital control applications. Weighing 10.5 kg and featuring a rated current of 50 A, this controller delivers precise command and regulation for asynchronous main spindle and frameless spindle motors in numerically controlled machine centers. With an analog Command Value input and a continuous effective current rating of 35 A, it provides smooth speed regulation and stable torque delivery for motors in the 3–10 kW power range.
Incorporating a modular design, the TDA 1.3-050-3-A0I integrates an internal position circuit specifically for its AC main spindle drive and a link circuit rated voltage of 300 V DC. The device operates exclusively inside a control cabinet, using internal airflow for cooling and ensuring optimal thermal management. It supports a b110 V analog speed command interface for seamless integration with standard NC controllers and features a dedicated slot for the AS programming module. Vertical mounting is mandatory to maintain proper heat dissipation and electrical clearance.
Compatibility with Bosch Rexroth 2AD and 1MB motor series ensures system coherence and simplifies installation. The controller’s robust design, combined with precise analog command processing, enhances drive stiffness and dynamic response. Its compact, vertical form factor and 10.5 kg mass facilitate retrofits and new installations alike. By offering reliable spindle control, high current capacity, and modular expandability, the TDA 1.3-050-3-A0I delivers exceptional efficiency and accuracy in demanding industrial environments.
