Product Description:

The DDS03.1-W030-DS29-02 drive controller is manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Classified as a digital AC servo drive controller, it regulates current and velocity for connected servo motors in multi-axis machining centers, packaging lines, and material-handling cells by converting commanded motion profiles into precisely timed motor currents. Installed in an automation cabinet, the unit links a higher-level motion controller to the servo motor and closes the electrical loop required for accurate positioning. The module works as the power stage between command signals and motor response, so the control system can correct deviations during acceleration, deceleration, and steady-speed operation.

Its SERCOS interface carries real-time setpoints over fiber-optic rings at deterministic cycle times, which supports synchronized data exchange with the motion system. Thermal management uses internal cabinet air to remove switching losses without external ducting, so enclosure airflow must reach the heat-producing sections of the module. The controller delivers up to 30 A of continuous output current, which is the maximum RMS phase current available to the motor windings, and position data return through digital servo feedback for closed-loop control with high-resolution encoder signals. The unit is part of Line 03, which matches it with compatible DC bus modules and auxiliaries that share the same footprint.

The controller is Version 1, so its signal pinouts and software parameters follow the initial release for this model. In a populated cabinet, it shares DC bus power rails, blower plenum positions, and mounting slots with neighboring modules. This arrangement keeps wiring orderly, supports consistent airflow around adjacent components, and preserves the established mechanical layout of the rack. It also helps maintain clear access to front-panel connections and status areas without requiring changes to the surrounding module positions.
