DDS02.1-W050-DL41-01-FW

The DDS02.1-W050-DL41-01-FW is a drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. In industrial automation, the unit forms the power and control bridge between a supply module and an AC servo motor, executing velocity and torque commands issued by a higher-level controller. Its rack-mountable housing integrates easily into modular drive cabinets.

At the control level, its interface supports single-axis position control, allowing the drive to manage one motor channel without external interpolators. The thermal design is based on air drawn from inside the control cabinet; therefore the cabinet airflow must be sized to remove the controller’s switching losses. Output capability is fixed at 50 A continuous current, so drive selection must match motor winding impedance and peak current demand. Position and velocity loops close through digital servo feedback, ensuring high-resolution monitoring of rotor angle. Configuration follows line 02 of the DDS platform, meaning hardware resources and connector layouts correspond to that line designation.

Additional parameters clarify ordering and integration details. The controller’s program memory is blank from the factory; its operating firmware must be ordered separately, letting the user match firmware revision to the target application. Motion functions are identified by code 01, a fixed function set maintained by Indramat that cannot be altered in the field. Internally, the device maintains a digital AC servo drive controller topology, combining signal processing with IGBT power stages to command synchronous or induction servomotors. Hardware revision corresponds to version 1, so replacement units must share this revision to maintain compatibility across a multi-axis rack.
