Product Description:

The DDS03.1-W030-DA01-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It forms the link between Indramat synchronous or induction motors and higher-level motion control, translating command signals into precise current and voltage patterns that regulate motor torque and speed in automated machinery. In a machine control system, it receives reference commands and adjusts the connected motor in real time so motion remains stable during speed changes, positioning moves, and load variation. This operating role makes it suitable for automation equipment that depends on repeatable axis behavior and consistent closed-loop performance.

The controller delivers a continuous output of 30 A, which is the maximum steady-state motor current the unit can supply without derating. Field wiring is handled through an ANALOG interface, so setpoint signals can be exchanged through standard voltage or current loops. Heat generated by the power stage is removed through internal air cooling, which uses cabinet air across the heat sink instead of requiring an external blower. The housing has an IP20 ingress rating, which provides touch protection but requires installation inside a protected enclosure. Motor position and velocity are returned to the drive through digital servo feedback, allowing the controller to maintain closed-loop regulation directly from encoder data.

The unit is intended for operation at elevations up to 1000 m above sea level. Its control electronics are designed for ambient temperatures from 0 – 45 °C during operation, supporting use in standard industrial cabinets with managed airflow. When power is removed, the controller can be stored at temperatures from –30 – 85 °C without damaging internal components. The listed revision is Version 1, and the controller belongs to Function ID 01 within the DDS platform. These operating and storage limits should be observed when selecting the cabinet location, planning ventilation, and handling the unit during transport or downtime.
