Product Description:

The DDS02.1-W015-RS04-03-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Installed in a multi-axis automation cabinet, the unit regulates torque, speed, and position for synchronous and induction motors used on material-handling stations, packaging lines, and machining centers. By exchanging real-time motion data with upstream control systems, it converts DC-bus energy into accurately timed phase currents for closed-loop industrial motion. Within a shared drive system, it serves as the power stage that responds directly to motion commands and motor feedback.

Communication with the higher-level control system is carried out through the SERCOS interface, allowing deterministic cycle times and standardized parameter access. The drive supplies up to 15 A of continuous output current, which suits medium-frame motors used in the DDS platform. A protection category of IP20 limits installation to enclosed cabinets where live parts are protected from accidental contact. The controller can operate in ambient temperatures from 0 to 45 °C without thermal derating under rated conditions. Position and velocity control rely on resolver feedback, making the unit suitable for motors that provide analog sinusoidal position signals.

Heat is removed by airflow drawn from inside the control cabinet across the heat sink, so the cabinet layout must support internal air circulation. This arrangement uses cabinet air rather than a separate external cooling path. Operation is permitted at elevations up to 1000 m above sea level before additional derating is needed. The electronics can be stored in temperatures from -30 to 85 °C, which supports transport and spare-part storage. The product belongs to Line 02, which matches the mechanical format used across that generation of DDS controllers.
