Product Description:

The DDS02.2-W050-BE12-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Positioned between the machine control system and the connected motor, it converts DC-bus energy from a supply module into regulated three-phase output while exchanging motion data over an optical link. The device is intended for industrial automation tasks that require precise torque and speed control, and it is commonly used in multi-axis assemblies where synchronized positioning is required. Because it operates from a shared DC bus, it fits cabinet-based drive systems that use a central supply module for multiple axes.

Connectivity is provided through the SERCOS interface, allowing deterministic data exchange with master controllers over fiber-optic cabling. Fiber-optic communication also helps isolate the command path from electrical noise generated by nearby power equipment. The power stage can continuously deliver 50 A, which supports servo applications that require sustained current during dynamic operation. A bare-board construction with finger-safe terminals sits behind an IP20 housing, so the unit must be installed in a protected cabinet. Thermal management relies on internal air cooling, and the controller remains fully functional in ambient temperatures from 0 to 45 °C when enclosure airflow is maintained.

For storage and non-operating periods, the drive can withstand temperatures from -30 to 85 °C, which supports transport and idle time without climate-controlled conditions. The controller can be mounted at elevations up to 1000 m above sea level without adjustment to its standard operating limits. Feedback input supports digital servo feedback and resolver feedback, allowing the drive to work with either high-resolution encoder systems or resolver-equipped motors. This flexibility supports both newer servo motors and older machine designs within the same platform. The unit is Version 2 and belongs to line 02.
