Product Description:

The DDS03.1-W030-DS12-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It converts DC bus energy into controlled three-phase output for coordinated servo axes. In automated packaging lines, material-handling gantries, and machine tools, the unit links motion commands from the PLC to the attached motor and regulates torque, velocity, and position through closed-loop control. Because the current and feedback loops are handled in the controller, the drive can respond quickly to load changes during positioning, speed regulation, and repeated start-stop cycles.

Command and diagnostic data are exchanged through the SERCOS interface, which provides deterministic fiber-optic communication between multiple drives. That communication method allows command values and status data to update at predictable intervals, which is important when several axes operate together. The controller delivers up to 30 A of continuous output current, making it suitable for medium-power synchronous motors, and thermal losses are removed by internal air cooling, which channels cabinet air across the heat sink without requiring external fans. The product is part of Line 03, and it uses digital servo feedback for electronic commutation and real-time error correction.

The unit carries Function ID Version 01, which identifies the assigned software set for this drive. The controller is Version 1, and it connects directly to regulated DC bus supplies used in multi-axis systems. It can also share a common bleeder module with neighboring axes, reducing the need for separate support hardware in the rack. This arrangement keeps the overall drive assembly compact while the controller continues to handle the motor-side regulation functions for its connected axis.
