Product Description:

The DDS02.2-W100-BE43-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Acting as the intermediary between a machine's motion control program and the connected servo motor, the device modulates three-phase power so the motor follows commanded torque, speed, or position profiles. In industrial automation, it is fitted into multi-axis printing, packaging, or machine-tool cabinets where synchronized drives share a common DC bus and require deterministic communication. Because it sits between the control system and the motor, it converts high-level motion commands into regulated output that the axis can use directly.

Its primary network link is the SERCOS interface, enabling real-time cyclic data exchange with a CNC or PLC at microsecond scan times. This communication path supports synchronized command updates and status reporting across the drive network. Thermal management relies on air from inside the control cabinet, so adequate airflow through the enclosure must be maintained to keep the power electronics within safe junction temperatures. The power section delivers up to 100 A of continuous output current, allowing the controller to drive mid-frame synchronous or asynchronous motors without derating. Position-loop feedback can be selected between digital servo feedback for high-resolution encoders and resolver feedback for rugged analog transducers, allowing the same controller platform to support different feedback devices.

The internal configuration is locked to Function ID Version 01, which keeps the controller aligned with its intended operating profile. The device is part of Line 02 and is Version 2, matching the mechanical dimensions and connector layout used throughout newer DDS racks. These identifiers correspond to the later DDS rack format used for matching connectors and mounting geometry. Application software is stored in a removable memory module, and the controller requires the correct program before operation. That program is supplied as a separate firmware subitem, allowing the same hardware base to be prepared for different machine functions.
