Product Description:

The DDS03.1-W030-RS03-01 digital AC servo drive controller is built by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. Intended for multi-axis automation racks, it regulates motor torque and velocity while exchanging real-time status data with higher-level motion controllers. By converting commanded setpoints into three-phase output, it provides precise position control for packaging machinery, pick-and-place stations, and other industrial equipment that demands coordinated servo motion. This allows the drive to support repeatable starts, stops, and speed changes during automated production cycles.

Communication is handled through the SERCOS interface, allowing deterministic fiber-optic networking between the drive, PLCs, and peer modules. The power stage supplies a continuous phase current of 30 A, supporting motors that must accelerate quickly without thermal derating. An enclosure rating of IP20 confines the unit to clean, shielded enclosures, so the specified cooling relies on air from inside the control cabinet rather than external blowers. Closed-loop regulation is achieved with resolver feedback, providing rotor angle information even at zero speed. Stable operation is permitted across an ambient range of 0 to 45 °C, allowing the controller to run alongside other electronics in standard cabinet installations.

The controller may be installed up to 1000 m above sea level without adjustment, and it can be stored safely between -30 to 85 °C. The unit belongs to Line 03 of the platform and uses Function ID version 01, so its operating profile matches the intended system group within the series. These identifiers help keep communication behavior and parameter structure consistent with compatible supply modules in the same rack. Hardware version 1 is also specified for this controller, and the storage range supports handling in warehouses or inactive cabinet assemblies before the unit is placed into service.
