Product Description:

The DDS03.1-W050-DS04-01 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It interfaces between a motion control CPU and synchronous servo motors, supplying regulated three-phase power while exchanging status and command data in real time. Used in printing presses, packaging lines, or assembly stations, the unit converts low-level velocity commands into torque-forming currents so the axis can follow repeatable positioning and speed profiles. The drive is suited to applications that require coordinated axis motion, stable current regulation, and consistent response during changing loads.

Communication with the host controller occurs over a SERCOS interface, which uses a light-based ring for high-speed cyclic data exchange. Thermal energy is removed by air from inside the control cabinet, so the enclosure must provide uninterrupted airflow to prevent overheating. During steady operation, the power stage can supply 50 A of output current. The housing carries an IP20 ingress rating, meaning fingers and similar objects are kept away from energized conductors, but the device relies on the cabinet for dust and liquid protection. Reliable function is maintained within 0–45 °C, which matches typical ambient conditions in industrial control enclosures.

Service limits extend beyond normal operation, with electronics able to withstand storage temperatures from -30 to 85 °C. Altitude use is approved up to 1000 m without changes to the stated load capability. Velocity feedback is delivered through digital servo feedback, allowing high-resolution position control and direct feedback processing by the drive. Product coding places the unit in Line 03, and it carries Function ID 01. The unit is Version 1, which identifies the product generation for this drive type.
