Product Description:

The DDS02.1-A050-DS04-01 drive controller belongs to the DDS Drive Controllers series manufactured by Bosch Rexroth Indramat. It serves as the axis power stage inside multi-axis machinery, converting DC bus energy into regulated three-phase output for AC servo motors. By processing motion commands from a master controller and supervising motor feedback, it maintains precise torque, speed, and position in automated packaging lines, printing presses, and material-handling gantries. The housing follows a modular rack format, so several units can be stacked side by side inside the main cabinet without special mounting hardware.

Its continuous output capability reaches 50 A, allowing the controller to drive medium-frame servomotors without derating. Command and diagnostic data travel over the SERCOS interface, so axis parameters stay synchronized to the PLC on a deterministic fiber ring. Thermal control relies on external air cooling, meaning ambient air from outside the enclosure is pulled through dedicated channels to remove switching losses. Rotor position is evaluated through digital servo feedback, which returns high-resolution data to the control loops for tight regulation. The unit belongs to Line 02, which matches the dimensions and connector placement used by other second-generation DDS modules.

The application-specific behavior is identified by Function ID version 01. This gives the unit a fixed command structure for its intended operating profile. Hardware revision 1 identifies the build level used for this controller. The unit is classified as a Digital AC Servo Drive Controller, allowing it to pair directly with compatible supply units and SERCOS masters. These identifiers clarify the controller type and operating profile without changing the electrical and feedback features described above.
