Product Description:

The DDS03.1-W050-DA02-00 is a digital AC servo drive controller from Bosch Rexroth Indramat for the DDS Drive Controllers series. It supplies regulated three-phase power to compatible servo motors so closed-loop motion tasks can be carried out in packaging lines, pick-and-place units, and other automated cells. The unit is part of line 03 and occupies a single slot in the modular rack, so additional axes can be added without changing cabinet depth. This format supports compact multi-axis cabinets where several drives must be arranged in a uniform layout.

An analog command channel forms the primary communication link, and the analog interface converts ±10 V velocity or torque references into PWM switching sequences for the output stage. During operation, the power section can deliver up to 50 A of continuous output current, allowing medium-frame motors to reach rated torque without derating. The housing has an IP20 protection category, which provides finger-safe access protection while requiring installation inside an enclosure for broader environmental shielding. Thermal loading is removed by air from inside the control cabinet, so the drive depends on cabinet airflow instead of a separate external cooling path. Electronic components remain functional from 0 to 45 °C, which suits typical industrial cabinet conditions.

Closed-loop position data enters through the built-in digital servo feedback connector, allowing the controller to process rotor information directly during acceleration and steady-speed operation. Reliable startup is permitted up to 1000 m above sea level; beyond that height, lower air density reduces convective cooling capacity. For storage or transport, passive components can tolerate ambient temperatures from -30 to 85 °C without damage to insulation materials or capacitive elements. The unit is revision 1, which keeps the control platform consistent with established parameter structures used on existing installations.
