Product Description:

The DDS02.1-A150-DA01-01-FW is a digital AC servo drive controller built by Bosch Rexroth Indramat within the DDS Drive Controllers series. It governs the current and velocity loops of compatible servo motors so they can be integrated into precise industrial automation axes. By converting command signals from a motion controller into regulated three-phase output, the unit serves as the link between the machine control layer and the mechanical load. In multi-axis equipment, it helps keep motion smooth during starts, stops, and changing load conditions.

The drive accepts setpoint commands over an analog interface, allowing ±10 V velocity or torque references to be applied to its internal control loops. Thermal extraction is handled by air drawn from outside the control cabinet, so the enclosure must provide a clear and unobstructed airflow path. During continuous motion, it can deliver a phase current of 150 A, allowing it to support larger compatible motors. All power and signal terminals are enclosed in an IP20 housing, which helps limit accidental contact with live parts but still requires installation in a protective rack. The controller operates in ambient temperatures from 0 to 45 °C without derating, which supports stable use in standard industrial cabinets.

Motor feedback is handled through Digital servo feedback, enabling high-resolution position data for closed-loop operation. This feedback method lets the drive process rotor information directly for accurate speed monitoring and stable response under changing load. The controller can be installed at elevations up to 1000 m, although higher locations may require cooling adjustments or derating. The storage temperature range is –30 to 85 °C, which helps protect the electronics during transit and storage. The unit belongs to Function ID 01, Function ID version 01, and Line 02 in the series, and it is identified as Version 1.
