Product Description:

The DDS02.2-W100-BE12-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Housed inside a control cabinet, it converts motion commands into regulated three-phase power that drives servo axes used in pick-and-place modules, printing units, and material-handling equipment. By combining power conversion, closed-loop regulation, and communication on a single frame, the controller becomes the electrical link between a higher-level motion CPU and the mechanical load. Its cabinet-mounted format keeps the power electronics near the motion control hardware while leaving the motor connected through external power and feedback cables.

The drive delivers a continuous output of 100 A. This is the maximum motor current it can supply without thermal derating. Cooling is achieved through air cooling from inside the control cabinet, so no external ducting or fan trays are required. Real-time command and diagnostic data are exchanged over the SERCOS interface, allowing deterministic fiber-optic bus cycles down to microsecond timing. Rotor position reaches the control loop through digital servo feedback, giving high-resolution encoder data for dynamic contouring, while an alternate channel accepts resolver feedback for motors that rely on inductive position sensing. This combination allows the controller to work with servo motors that use either encoder-based or inductive position feedback.

This controller belongs to Line 02, so connector placement and bus pinouts match other modules from the same release. The unit is Version 2, which expands parameter memory and diagnostic depth compared with the initial revision. Within the DDS Drive Controllers series, the module layout supports side-by-side installation in mixed-axis cabinets. It also mates directly with compatible Rexroth power supplies and extension cards without additional brackets, and it fits standard cooling spaces between adjacent modules.
