Product Description:

The DDS02.2-A100-BE45-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed between the machine control network and a matched servo motor, it converts three-phase supply energy into modulated output current while monitoring torque, speed, and position. This unit forms the active link that closes the motion control loop in industrial automation cells where precise axis coordination is required. Because current regulation and feedback evaluation are handled inside the controller, the connected axis can respond quickly to changing load conditions without losing commanded position.

The drive exchanges setpoint and diagnostic data through the SERCOS interface, enabling deterministic fiber-optic communication with multiple axes on a single ring. Its power stage can supply a continuous output of 100 A, so applications with high peak-torque demands can be served without oversizing the cabinet. Heat is removed by air from outside the control cabinet, so ambient air moves across the heat sink instead of recirculating warmed cabinet air. This cooling method helps keep cabinet heat buildup lower in dense control panels. Position information returns over digital servo feedback, allowing high-resolution encoder data to reach the controller's current and velocity loops. The unit is part of Line 02, which uses connector layout and mounting dimensions consistent with other components in the same line.

An auxiliary channel accepts resolver feedback, offering a rugged alternative when optical encoders face shock or contamination. That option is useful in applications where signal robustness is preferred under vibration or contamination. Control parameters are locked to Function ID Version 01, keeping the unit aligned with its assigned operating profile. The product is Version 2, which reflects the specified design revision for this drive. In addition, firmware ordered as a separate subitem is required before operation, so the software package can be selected to match the intended motion application.
