Product Description:

The DDS03.1-W030-RS03-02 is a digital AC servo drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Designed for cabinet-mounted motion systems, the device receives numeric velocity and position commands from a central controller and modulates power for servo motors so that automated axes follow programmed profiles with repeatable accuracy. It supplies regulated current, supervises motor feedback, and manages protective functions between the machine control platform and the mechanical load in industrial assembly lines, printing modules, and material-handling stations. This arrangement lets the drive handle motor regulation locally while the higher-level control manages sequence logic and axis coordination.

Communication with the higher-level automation bus is handled through the SERCOS interface, a fiber-optic protocol that delivers deterministic cycle times necessary for multi-axis synchronization. The drive can supply up to 30 A of continuous output current, allowing it to energize medium-frame servo motors without saturation. Thermal energy is removed by internal air cooling, so cabinet airflow must be maintained and no external heat sink is required. Electrical parts are guarded to IP20, which permits finger-safe access but assumes installation inside an enclosure. Reliable function is maintained across an ambient operating window of 0 to 45 °C, so the unit can be placed next to other heat-generating drives in standard control cabinets.

Motion feedback is processed through resolver feedback, giving absolute rotor angle information even during power interruptions and eliminating the need for a battery-backed encoder. This feedback method also supports stable commutation and speed control during repeated starts and stops. Installation heights up to 1000 m above sea level are supported without derating, which suits most plant floors. When powered down, electronic components remain stable through a storage range of -30 to 85 °C, allowing the unit to tolerate broad temperature variation before installation. The unit is part of the 03 line and uses design version 1, matching the parameter structure used across comparable DDS modules.
