Product Description:

The DDS03.1-W030-DA11-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. As part of line 03 of this platform, the unit converts DC-bus power into regulated three-phase output for servo axes in packaging machines, printing stations, and other automated equipment. It receives motion commands from higher-level control hardware and translates them into controlled motor current so the connected axis can respond smoothly to changing process demands. In a closed-loop system, this role allows the drive to maintain stable torque during acceleration, deceleration, and load variation. This makes it suitable for applications that require repeatable speed response and controlled torque delivery during frequent start-stop cycles.

Its command channel uses an analog interface, so speed and torque references arrive as voltage signals for processing by the control stage rather than through a digital network. Thermal management relies on internal air cooling, meaning cabinet air passes across the heat sink without separate external ducting. Under continuous duty, the power section delivers 30 A of controlled output current. The enclosure is rated IP20, which suits installation inside ventilated control cabinets and helps prevent accidental finger contact with live parts. Reliable operation is permitted at ambient temperatures from 0 - 45 °C, provided normal cabinet airflow is maintained around the unit. Because the command structure is analog, the drive fits systems that use external control cards or PLC outputs with voltage reference signals.

Operation is permitted up to 1000 m above sea level without current derating. Position and velocity closure at the motor are handled through digital servo feedback, giving the controller real-time rotor data for accurate regulation during both steady running and rapid speed changes. The feedback channel lets the drive compare commanded motion with actual motor behavior and correct deviations quickly. When stored or transported, the unit tolerates temperatures from -30 - 85 °C. This storage range is suitable for common warehouse and shipping conditions before installation. The controller uses version 1 for this release.
