Product Description:

The DDS03.1-W050-RA02-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Intended for industrial automation, the unit supplies regulated three-phase current to matched servo motors so that velocity and position follow upper-level commands with consistent response. By converting control-system signals into precise motor current, the controller forms the closed-loop interface between PLC logic and the mechanical axis. This supports repeatable motion profiles in packaging lines, material transfer stages, and other electromechanical assemblies that depend on accurate servo regulation during repeated operating cycles.

The drive can deliver a continuous current of 50 A, giving it enough output capacity for medium-frame servo motors in sustained operation. Command data enters through an analog interface, so speed or torque setpoints are transmitted as voltage or current references instead of network-based commands. Rotor position is returned through resolver feedback, enabling sinusoidal commutation and stable closed-loop regulation across changing load conditions. Heat generated by the power section is removed by internal air cooling, so cabinet airflow moves across the heat sink rather than depending on an external blower. The unit is assigned to Line 03, which places it in the third design line of this platform and matches it with the corresponding mechanical layout and connection style.

The hardware is built as Version 1, which identifies the initial release of this platform. Its layout supports cabinet installation where consistent connector placement and predictable control behavior are important in multi-axis assemblies. The controller serves as the link between upper-level command electronics and the motor power stage, so accurate current regulation remains central to axis performance. This model is suited to machinery that requires repeatable servo motion and straightforward command handling in applications that use analog reference signals for control.
