Product Description:

The DDS02.2-W200-BT31-01-FW is a drive controller built by Bosch Rexroth Indramat within the DDS Drive Controllers series. Classified as a digital AC servo drive controller, it regulates power to synchronous and induction servomotors used for coordinated motion in machine tools, packaging lines, and material-handling equipment. The unit mounts on a modular backplane next to the shared power supply, allowing it to operate as part of a compact multi-axis drive arrangement inside the control cabinet. This design lets the controller serve motor applications that require synchronized movement and stable current regulation.

It uses internal air cooling that draws air from inside the control cabinet rather than from the surrounding machine environment. This arrangement simplifies cabinet sealing but depends on clean forced airflow from the panel, and the power stage can continuously source 200 A under rated ambient conditions. For precise control loops, the unit evaluates encoder signals from motors fitted with digital servo feedback, and it can also process resolver feedback when lower-frequency analog tracking is preferred. The unit carries Function ID 01, which sets the available parameter range and operating behavior for this controller type. That flexibility allows the same power section to work with different motor feedback technologies used across installed systems.

Within the DDS hardware hierarchy, the controller is part of Line 02, which uses second-generation signal boards and standardized front-panel connectors. Hardware revision 2 uses updated semiconductor packages to improve switching efficiency and reduce thermal load during sustained operation. When installed with compatible supply and bleeder modules, the controller shares a common DC bus, allowing multiple axes to exchange regenerated energy and brake through a centralized resistor bank. The shared bus architecture also allows braking energy from one axis to be used by another axis that is accelerating at the same time.
