Product Description:

Bosch Rexroth Indramat manufactures the DDS02.2-W100-BE77-00-FW as part of the DDS Drive Controllers series. This drive unit functions as the axis amplifier inside modular automation cabinets, supplying controlled three-phase power to matched Indramat servo motors. Within a multi-axis lineup, the controller exchanges real-time process data with higher-level motion cards so that velocity, torque, and position loops are closed at the drive level. That layout supports compact wiring and centralized diagnostics in production machinery such as transfer systems, packaging equipment, and other coordinated servo installations.

The controller is rated for a continuous output of 100 A, which allows it to supply substantial motor current before protective limits intervene. Command data is carried over the SERCOS interface, a fiber-optic ring that transfers setpoints and status words with deterministic timing. Internally, heat is removed by air drawn from inside the control cabinet, so enclosure airflow must meet the ventilation needs of the rack. Encoder return is handled by digital servo feedback, while compatibility with resolver feedback allows the same drive to operate older motor generations. The hardware is part of Line 02, and Version 2 identifies this revision of the unit.

The unit is a digital AC servo drive controller intended for coordinated servo applications in cabinet-based systems. Parameter data can be loaded through the optical service channel, and the diagnostic structure reports faults related to cabinet temperature, link voltage, and feedback plausibility. These functions support clear status monitoring in master-slave axis groups and other coordinated motion systems where several drives operate together under one control architecture and share common operating conditions. It can therefore be used in systems that need both fast communication and clear fault reporting.
