Product Description:

The DDS02.1-W050-DS01-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It regulates torque, speed, and position loops for synchronous and induction servomotors in modular automation systems. By exchanging real-time command and status data with higher-level motion controllers, the unit supports coordinated multi-axis operation in gantries, packaging stations, and transfer modules. Closed-loop control lets the drive correct load changes quickly so commanded motion remains stable during acceleration, deceleration, and precise positioning tasks.

The controller communicates over the SERCOS interface, allowing fiber-optic ring networks to carry both control words and diagnostic data with very short cycle times. This communication method supports synchronized data exchange between the drive and the rest of the motion system. Its continuous output capability is 50 A, so the associated power distribution hardware must be sized for that current under sustained load. Cooling uses air drawn from inside the control cabinet, which requires an unobstructed airflow path to remove switching losses. The housing has an IP20 protection rating, which is finger-safe but not sealed against dust, so installation in a closed cabinet is required. Reliable operation is permitted from 0 to 45 °C, provided nearby equipment does not raise the ambient temperature beyond that range.

The drive processes motor encoder signals through its digital servo feedback input, providing absolute position data directly to the control loop. This direct feedback path helps the controller maintain accurate speed and position regulation without relying on slower external processing. Full performance is maintained up to 1000 m above sea level, which suits standard factory elevations without derating. During storage, the electronics tolerate ambient conditions from -30 to 85 °C without requiring climate-controlled space. Configuration parameters are tied to Function ID 01.
