Product Description:

The DDS03.1-W030-RS01-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It is intended for cabinet-mounted motion axes where compact electronics modulate current to synchronous or asynchronous servomotors under CNC or PLC command. By converting mains power into controlled three-phase output while exchanging real-time data with higher-level automation, the unit maintains coordinated speed and position loops throughout industrial assembly, packaging, and material-handling stations.

Communication with the host control system occurs over the SERCOS interface, a fiber-optic ring that guarantees deterministic cycle times for multi-axis drives. The power stage delivers up to 30 A of continuous output current, matching medium-frame motors without oversizing the supply transformer. Protective ingress is limited to the cabinet interior because the housing carries an IP20 rating, so it must be installed behind a sealed panel. Heat is removed by internal air cooling, meaning cabinet airflow must move across the heat sink to keep semiconductor junctions within the specified 0 – 45 °C operating window. Altitude capability reaches 1000 m above sea level before derating is required.

Long-term service considerations center on environmental storage, feedback compatibility, and firmware identity. When de-energized the unit tolerates ambient extremes from -30 – 85 °C, allowing safe transport or spares inventory in unconditioned warehouses. Motor position data is reconciled through resolver feedback; this analog transducer permits reliable commutation even under electrical noise that could upset digital encoders. Product identifiers embedded in the firmware define application features: Function code 01 selects a fixed software option set, while line designation 03 and hardware version 1 align with matching supply modules and backplane connectors used across the DDS platform.
