Product Description:

The DDS02.2-A100-BE76-01-FW is a digital AC servo drive controller built by Bosch Rexroth Indramat within the DDS Drive Controllers series. It is installed in modular drive racks where it supplies closed-loop current and speed control to synchronous or induction motors that position axes in machine tools, presses, or assembly stations. By coordinating with higher-level motion processors, the device converts command words into regulated three-phase output so that each motor follows programmed profiles without overshoot or drift.

The drive delivers a continuous output of 100 A, giving it headroom for high-torque acceleration while maintaining thermal limits. Command and diagnostic data move over the SERCOS interface, allowing deterministic fiber-optic networking with multiple drives on one ring. Heat is removed by external air cooling, so mounting guidelines require unobstructed airflow through cabinet openings to keep the power electronics below rated junction temperatures. Rotor position is returned through digital servo feedback or resolver signals, allowing the controller to support either high-resolution commutation or a more rugged feedback method. An IP20 housing helps protect against contact with live parts, but the unit must be installed in a closed electrical enclosure.

Ambient service is allowed between 0 to 45 °C, so the cabinet climate system must prevent hot-spot formation during peak production. Altitudes up to 1000 m above sea level are accepted without current derating because reduced air density above this height can impair heat transfer. For warehouse storage, the electronics withstand a range of -30 to 85 °C without condensation. Configuration files reference Function ID 01, ensuring that parameter blocks downloaded from supervisory controllers call the correct drive functions for this second-generation line.
