Product Description:

The DDS03.1-W030-DS03-02-FW is an AC servo drive controller built by Bosch Rexroth for the DDS Drive Controllers series. Integrated into multi-axis automation racks, the unit converts DC bus energy into regulated three-phase output that governs torque and speed on connected motors. Within an industrial cell, it acts as the intermediary between a central motion processor and the electromechanical load, supplying the commanded current profile while monitoring feedback to maintain positional accuracy.

It delivers a continuous output rated at 30 A, a current range suitable for mid-frame synchronous or induction servomotors that require moderate peak torque without oversizing the power stage. Communication with the master controller occurs over a SERCOS interface, which carries cyclic setpoints and parameter data on a fiber-optic ring for noise immunity. Thermal management relies on internal air cooling; the drive draws cabinet air across its heat sink, so enclosure airflow must match the dissipated losses. Rotor position is evaluated through digital servo feedback, allowing high-resolution velocity loops without separate tachometers. The drive belongs to Line 03, which supports 24 V logic and standardized bus bars, and Version 1 indicates the initial revision of this line.

For this drive, the parameter set resides in a removable module rather than inside the base unit, and it must be ordered as a separate firmware subitem to match the application program. Once the code module is installed, the electronics operate as a Digital AC Servo Drive Controller, offering interpolated position control alongside velocity and torque modes. It is compatible with auxiliary supply modules, mains rectifiers, and motion cards used in the DDS platform. It is used in centralized machine cabinets that already contain other DDS axes and shared control hardware.
