Product Description:

The DDS02.2-W050-BE95-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat. It supplies controlled three-phase power to synchronous or induction motors in industrial automation, allowing a higher-level PLC to command motion with accurate velocity and torque regulation inside the control cabinet. Acting as the power stage between the control system and the motor, the unit supports repeatable axis movement during speed changes, load variation, and routine positioning tasks on production machinery. Its purpose is to convert commanded operating values into regulated motor current so the axis follows the requested motion profile with stable closed-loop behavior instead of open-loop motor operation.

The unit has a continuous output capability of 50 A, allowing it to energize medium-power servo motors without current derating under normal ambient conditions. Communication with the machine control layer occurs over the SERCOS interface, which carries cycle-synchronous setpoints and feedback through a fiber-optic ring for coordinated axis control. Heat is removed by internal air cooling, so cabinet air is drawn across the heat sink and no external fans or liquid circuits are required. Position data from the motor is returned through digital servo feedback, enabling the controller to make fine torque corrections during each control cycle. Because command and feedback data are exchanged continuously, the drive can respond quickly to changing load conditions, repeated start-stop cycles, and speed demands.

Where higher noise immunity or older transducers are present, the unit can instead close the loop with resolver feedback. The product is part of Line 02, which places it in the second platform revision used for this drive range. The control electronics are released as Version 2, indicating a later internal revision for this model. It belongs to the DDS Drive Controllers series and is intended for multi-axis cabinet systems that share bus couplers, breaker modules, and airflow paths across centralized automation racks. Such systems often place several coordinated axes in the same enclosure, using common airflow and shared power distribution.
