Product Description:

The DDS03.3-W030-B is a drive controller produced by Bosch Rexroth Indramat and offered within the DDS Drive Controllers series. It is designed to coordinate servo or induction motors in automated cells, issuing torque, velocity, and position commands for synchronized axes used in material handling, printing, and packaging equipment. By combining power electronics with drive-based diagnostics, the unit forms the interface between a supply module and connected motor feedback devices. This arrangement allows the drive to support closed-loop motion control while remaining integrated within a cabinet-based automation system.

The controller uses air cooling from inside the control cabinet, so heat is removed by the enclosure airflow without external ducts or blowers. During continuous duty, it delivers a rated current of 30 A to the motor, which suits medium-power positioning tasks. Its housing meets the IP20 protection category, so the unit is intended for installation in a closed cabinet. Full performance is maintained at ambient temperatures from 0 to 45 °C, which supports operation in standard industrial enclosures. This allows several axes to share the same cabinet when airflow is managed correctly. Velocity and position are monitored through digital servo feedback and resolver feedback, allowing the controller to work with either encoder-based or resolver-based motor feedback.

Operation is permitted at elevations up to 1000 m above sea level without reducing output. In storage, the unit withstands temperatures from -30 to 85 °C, which helps protect passive components during non-operating periods. The product is part of Line 03 in the DDS platform. As a Digital AC Servo Drive Controller, it connects directly with compatible Indramat supply sections and standardized motor cables, and typical DDS cabinet layouts do not require external converters or separate relay interlocks.
