Product Description:

The DDS03.1-W050-RA01-00 is a servo drive controller supplied by Bosch Rexroth Indramat within the DDS Drive Controllers series. It regulates three-phase motor power by converting DC bus energy into precise AC output so closed-loop servo axes can position and follow velocity commands in automated machinery. In combination with matched motors and feedback devices, the unit serves as the motion node that links a PLC command layer to electromechanical actuation on the factory floor. This arrangement supports coordinated motion in equipment that requires stable speed control, repeatable positioning, and responsive torque regulation during changing load conditions.

The drive’s continuous output capability is rated at 50 A, allowing it to energize medium-frame servo motors without current foldback during acceleration or sustained torque demand. Command values are accepted through an analog interface, so velocity or torque setpoints can be delivered as ±10 V signals from legacy motion controllers. Rotor position is returned to the controller through resolver feedback, providing angle information that remains dependable in electrically noisy environments. Component heat is removed by internal cabinet air cooling, so the unit relies on enclosure airflow rather than an external heat sink. For personnel and equipment safety, the drive is housed in an enclosure that meets the IP20 protection category, which limits finger access to live parts while permitting installation in ventilated racks. This combination of control input, feedback method, and cooling style makes the unit suitable for cabinet-based servo systems with centralized power conversion.

The unit belongs to Line 03 and uses Function ID 01 with Version 1 for the standard control arrangement of velocity and torque loops. The controller maintains full performance up to 1000 m elevation where cooling air density remains adequate for normal heat removal. Its operating range is 0–45 °C during powered service, and its storage range is -30–85 °C when the cabinet is de-energized. These temperature limits allow the drive to be stored, transported, and installed in typical industrial indoor environments without requiring special handling beyond normal cabinet protection.
