Product Description:

Bosch Rexroth Indramat manufactures the DDS02.1-W015-RS01-03-FW, a digital AC servo drive controller in the DDS Drive Controllers series. In industrial automation, it modulates three-phase output current so connected servomotors can follow velocity or position commands from a higher-level motion controller. Acting as the power stage between the PLC and the motor, the unit supports precise and repeatable motion in assembly cells, material-handling lines, and process equipment. It regulates motor current in response to motion commands and axis feedback. This allows the machine control system to maintain stable speed control and accurate positioning throughout repeated production cycles.

The controller exchanges setpoint and status data through the SERCOS interface, a deterministic fiber-optic bus that supports real-time drive networking. During continuous duty, it delivers up to 15 A of motor current, allowing medium-power axes to accelerate without saturation. The housing has an IP20 rating, which provides finger-safe openings but no water sealing, so installation inside a closed cabinet is required. Heat is removed by internal air cooling, and reliable operation is maintained in ambient temperatures from 0 to 45 °C. Because cooling air is taken from the cabinet interior, the enclosure should provide clean airflow around the heat sink.

Rotor position is evaluated with resolver feedback, which provides analog angle information that resists electrical noise and high shock levels. This feedback method supports dependable commutation and speed monitoring in demanding industrial environments. The drive can be mounted at elevations up to 1000 m without derating, making it suitable for facilities on moderate plateaus. For warehouse or transit periods, it tolerates storage temperatures from -30 to +85 °C. The unit carries Function ID 01, belongs to Line 02, and is Version 1.
