Product Description:

The DDS03.1-W030-RC01-00 is a digital AC servo drive controller built by Bosch Rexroth Indramat and placed within the DDS Drive Controllers series. It serves as the axis inverter for compatible synchronous and induction motors in multi-axis industrial automation systems. In cabinet-based motion equipment, it converts bus power into controlled motor current for coordinated axis movement. By linking with plant PLC networks, the unit regulates speed, torque, and position so packaging machines, printing lines, and material-handling modules can follow commanded motion profiles with repeatable accuracy.

Field-level communication is handled through the INTERBUS-S interface, letting the drive exchange setpoints and diagnostic data over a serial bus topology. This allows higher-level control equipment to send commands and receive status information during machine operation. During operation, the power stage can deliver a continuous phase current of 30 A, which indicates the load the controller can support without thermal derating. Heat is removed by internal cabinet air cooling, so the enclosure must provide enough airflow across the unit. The electronics are housed in an IP20 enclosure, which protects against accidental finger contact with live parts but still requires installation inside a closed cabinet. The permitted ambient operating range is 0–45 °C, so higher temperatures call for reduced current or added cooling.

The device maintains functional integrity up to 1000 m above sea level, allowing use on most factory floors without altitude derating. Motor position is evaluated through resolver feedback, a transformer-based feedback system that provides reliable rotor-angle information under electrically noisy conditions. This feedback method is often used where vibration and interference can affect more sensitive signal types. The unit carries Function ID 01 and belongs to Line 03, and it is version 1 within this controller type. Storage is permitted from -30 °C to 85 °C, and these identifiers set the available parameter structure, fault handling, and compatible option cards.
