Product Description:

The DDS02.1-A100-RA02-02-FW is a drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Designed for closed-loop servo regulation, it receives command signals from higher-level motion processors and modulates power for the attached motor. Internally, the unit uses digital current loops to support smooth acceleration and stable motor control across the speed range. By coordinating torque, speed, and position, it serves as an integral component in automated machinery such as gantries, packaging stations, and material-handling axes. Its control concept is suited to applications that require repeatable motion and consistent response during changing load conditions.

Its power stage is rated for a continuous output of 100 A, allowing the controller to supply sizable synchronous or induction motors without current derating. Command values are accepted through an analog interface, which simplifies integration with motion racks that already use analog ±10 V speed or torque references. Rotor position is returned through resolver feedback, giving the drive phase information at all speeds for rapid commutation and stable closed-loop operation. The enclosure has an IP20 rating, which protects against finger contact and larger solid objects when the unit is installed inside a cabinet. This combination of power capacity, analog command input, and resolver-based feedback makes the controller suitable for a wide range of servo applications.

Heat is removed by external air cooling, so cabinet airflow must carry heat away from the power section rather than rely on internal recirculation alone. The controller maintains full performance in ambient temperatures from 0 to 45 °C, and it can be stored at temperatures from -30 to 85 °C when not in operation. Continuous use is permitted at installation altitudes up to 1000 m without output reduction, which covers most standard industrial locations. The product is part of Line 02 and is version 1. These operating limits support reliable use in enclosed automation cabinets with properly managed airflow.
