Product Description:
The DDS03.1-W30-R is a digital servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It operates as the closed-loop interface between the power supply module and an Indramat synchronous or induction motor, delivering regulated three-phase output to match commanded torque and velocity setpoints. Within an industrial automation cabinet, the unit coordinates motion axes, evaluates feedback signals, and exchanges status data with higher-level PLCs so that machine tools, packaging stations, and material-handling gantries maintain accurate and repeatable movement. This arrangement allows the drive to respond quickly to changing load conditions while keeping motor operation stable during acceleration and steady-speed travel.
Cooling is provided by internal air cooling, meaning the drive uses air already inside the control cabinet rather than relying on an external fan circuit. The enclosure is rated IP20, which helps prevent accidental contact with live components but requires installation in a protected electrical enclosure. Classified as a Digital AC Servo Drive Controller, the device includes current-mode control loops and digital parameter storage to match Indramat motor characteristics without manual trimming. The unit is part of Line 03 and Version 1, which identify its place within the series and help distinguish it from other drive revisions. Cabinet airflow must be planned so the heat sink can release internal losses without exceeding the allowable operating temperature.
The permissible ambient range of 0 – 45 °C keeps internal components within normal operating temperature limits during use. A storage window of -30 – 85 °C protects the drive during transport and long-term storage when it is not powered. Installation altitude is capped at 1000 m, and operation above that height requires derating because lower air density reduces cooling effectiveness. Bosch Rexroth Indramat lists these operating limits for use in protected control cabinets where the drive is installed with suitable ventilation and environmental protection.
