TDA 1.3-100-3-LP0

The Bosch Rexroth Indramat TDA 1.3-100-3-LP0 from the TDA Main Spindle Controllers series delivers precision spindle control with a rated current of 100 A and a continuous effective current of 70 A through a robust SERCOS interface. This controller weighs 10.5 kg and features a 300 V DC link circuit rated voltage for stable power delivery. With a high-resolution rotor feedback system achieving 1/2 000 000 revolutions accuracy, the TDA 1.3-100-3-LP0 sets the benchmark for spindle positioning performance. Its additional encoder input provides a second feedback signal for synchronous operations and advanced motor diagnostics.

Built for industrial environments, the TDA 1.3-100-3-LP0 carries an IP10 protection class per DIN 40 050, guarding against solid objects over 50 mm while allowing unhindered airflow. Classified under Humidity Class F according to DIN 40 040, it operates reliably in cold, hot, and dry conditions up to a maximum operating altitude of 1 000 m above sea level. The controller supports real-time speed commands via the SERCOS interface, ensuring deterministic communication with CNC masters. Its design tolerates ambient temperatures from +5 °C to +45 °C and up to a peak of +55 °C for uninterrupted spindle handling.

Engineered for seamless integration, the TDA 1.3-100-3-LP0 main spindle controller features no additional interfaces beyond its dual encoder channels, minimizing wiring complexity and reducing panel footprint. Its lightweight 10.5 kg chassis simplifies mounting in high-density machine tool cabinets while delivering uncompromised SERCOS-based command value performance.
