Product Description:

Bosch Rexroth Indramat manufactures the DDS03.2-W015-BE12-01-FW for inclusion in the DDS Drive Controllers series. The unit is a digital AC servo drive controller intended to power and regulate synchronous or induction motors in industrial automation. Installed on a common backplane inside a control cabinet, it receives low-level commands from a motion controller and converts them into precisely timed voltage vectors, enabling accurate torque, speed, and position control along a machine axis. Compact dimensions support multi-axis installations, while plug-in power and logic connectors simplify cabinet integration.

The drive exchanges cyclic setpoints and feedback with the master through the SERCOS interface, a fiber-optic fieldbus that provides deterministic data transfer and electrical isolation. Drive output is limited by a rated phase current of 15 A, so it is intended for motors whose continuous demand does not exceed that value. Heat produced by the output stage is removed by internal air cooling, meaning cabinet airflow must pass through the unit to keep the heat sink within its temperature limit without external ducting. Position data can be processed through digital servo feedback, while legacy or cost-optimized axes can use resolver feedback; the controller automatically identifies the selected sensor and adjusts its commutation algorithm accordingly.

Operating parameters are set by a separate firmware subitem, which lets the same hardware support different application profiles. The basic function set is identified as Function ID Version 01, which indicates the permissible command set within the DDS family. The product is part of Line 03, and its hardware is built as Version 2. These identifiers distinguish the unit within the series and describe its design status for compatible system use.
