Product Description:

The DDS03.1-W030-RS04-03-FW is part of the DDS Drive Controllers series and is manufactured by Bosch Rexroth Indramat. It is a digital AC servo drive controller that regulates torque, speed, and position for synchronous and induction motors used in automated machinery and material-handling stations. By converting command data from the control network into regulated three-phase output, the unit forms the link between motion control logic and the motor's power stage inside a protected control cabinet. This arrangement lets the controller translate machine commands into controlled motor response during positioning, speed changes, and routine production cycles.

Data exchange with the host motion system is handled through a SERCOS interface, which provides deterministic fiber-optic communication for coordinated multi-axis operation. Continuous output is limited to a rated current of 30 A, so the drive is suited to applications that stay within that steady-load range. Heat from the power electronics is removed by air drawn from inside the control cabinet, so the enclosure must maintain adequate airflow during operation. Rotor position reaches the controller through resolver feedback, which resists electrical noise and provides absolute angular information.

The unit follows the functional profile of a Digital AC Servo Drive Controller, so parameter access, diagnostics, and protective trips are available through the control interface. Within the series, the product is part of Line 03, and the drive is Version 1. These identifiers mark the design generation used for this controller and distinguish it from other DDS variants. The control structure supports closed-loop operation during positioning, speed regulation, and repeatable machine cycles. It can be integrated where the drive must respond consistently to network commands while maintaining regulated motor current in cabinet-mounted systems.
