Product Description:

The DDS03.2-W030-BE41-02-FW drive controller is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It translates motion commands from CNC or PLC equipment into regulated current for servo motors, supporting the velocity, torque, and position loops used in automated assembly, packaging, and material-handling stations. The drive regulates motor current quickly so the connected axis can respond accurately to changing commands and load conditions. By combining power electronics and communication functions in one unit, the controller helps reduce cabinet complexity while supporting coordinated multi-axis operation.

The controller exchanges real-time data over a SERCOS interface, which provides deterministic fiber-optic communication between the control system and connected drives. This communication method supports synchronized command updates and status reporting across linked axes. It can deliver up to 30 A of continuous output current, making it suitable for medium-frame motors that require steady current during acceleration and load changes. Heat generated by the power section is removed through internal air cooling, so the cabinet must provide moving air rather than depend on external fins. The housing has an IP20 rating, and the permitted ambient range is 0 – 45 °C with installation below 1000 m. Because of that enclosure rating, the controller is intended for mounting inside a protected cabinet rather than in open machine areas.

For motor feedback, the controller accepts either digital servo feedback or resolver feedback, allowing it to operate with motors that use different position-sensing methods. This flexibility supports systems that use either encoder-based or resolver-based motor packages without changing the basic controller platform. When powered down, the electronics tolerate storage temperatures from -30 – 85 °C, which supports transport and warehouse storage before installation. The product is assigned to line 03 and version 2, matching the identified hardware release of this controller.
