Product Description:

The DDS03.1-W050-DA01-01-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It operates as a digital AC servo drive controller that governs torque and speed loops for synchronous and induction motors used in industrial automation cells, machine tools, and similar motion systems. By converting command signals from higher-level motion processors into regulated three-phase power, the unit links the CNC or PLC to the motor. It is intended for applications where the motor must respond accurately to changing load and speed commands during coordinated motion.

The controller exchanges setpoint and diagnostic data through an analog interface, so legacy motion cards can issue voltage references without protocol conversion. Thermal management uses air drawn from inside the control cabinet, and this internal flow path keeps the heat sink within operating limits without external ducts. A continuous output capability of 50 A allows the drive to power medium-frame servomotors during rapid acceleration and sustained holding phases. Position verification is supplied through digital servo feedback, enabling closed-loop operation with high-resolution encoders and stable speed regulation. This feedback path also lets the controller compare commanded and actual motor behavior in real time for consistent control performance.

The drive uses Function ID 01 together with Function ID Version 01, which indicates the supported control feature set for this model. Within the DDS architecture, the device is in Line 03, placing it in the third power class of the modular rack. The unit is Version 1, which marks the release level for its mechanical layout, connector arrangement, and parameter range. These identifiers organize the drive within the DDS product structure and distinguish it from units with different control and power combinations.
