Product Description:

The DDS03.2-W030-BE12-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. In an automation cell, it links the power stage of an electric servo axis with higher-level motion hardware, converting network commands into regulated three-phase output that drives the connected motor. By integrating into a multi-axis rack, the unit supports coordinated positioning, velocity loops, and diagnostic exchange within CNC machines, material handlers, or packaging lines. It also passes operating data needed for axis monitoring during normal machine operation.

The controller communicates over a SERCOS interface, so timing-critical telegrams for setpoints and feedback travel on a fiber-optic ring rather than on serial wiring. A rated output of 30 A is the continuous phase current that the power section can supply without derating, matching mid-frame servomotors used on 3 kW to 6 kW mechanical loads. Heat is removed by air drawn from inside the control cabinet, so this internal cooling method requires suitable airflow within the enclosure. Position verification is possible because the drive processes digital servo feedback signals, delivering high-resolution angle data to its control loops. When a motor uses analog angle tracking, the unit also accepts resolver feedback, giving flexibility across mixed motor families.

Application software is not permanently installed and must be ordered as a separate subitem, allowing the same hardware to be used for different motion functions. Configuration parameters are locked to Function ID version 01, so the software expects this fixed functional feature set. Hardware generation is identified by Line 03, while the mechanical and electronic refinements applied to that generation are labeled hardware version 2. These identifiers indicate the functional and hardware revision used by the drive and the electrical interfaces expected for this controller type.
