Product Description:

The DDS03.1-W050-DA02-01-FW is a servo drive produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It installs inside a multi-axis cabinet and regulates AC servo motors by converting DC bus power into controlled three-phase output. This allows coordinated motion in automated machinery such as gantries, packaging stations, and handling units. In a complete drive system, the unit serves as the power and control stage between the shared cabinet supply and the connected motor. Because it is intended for cabinet installation, it works with other modules in the drive assembly rather than as a stand-alone inverter.

The control board exchanges velocity or torque commands through an analog interface, so ±10 V setpoints from a PLC can be processed without fieldbus hardware. This arrangement supports applications that use standard analog command signals from existing machine controls. Heat generated by the IGBT stage is removed through internal air cooling, and cabinet airflow passes directly across the heat sink instead of using an external blower module. Continuous motor demand is supported by a rated output of 50 A, which gives the drive current capacity for dynamic acceleration during normal operation. Rotor position is reported through digital servo feedback, enabling high-resolution closed-loop control and automatic commutation alignment at startup. The feedback channel also lets the drive monitor rotor movement continuously for stable speed regulation and accurate positioning. The required operating software is ordered separately from the base unit.

The unit is part of Line 03, which uses the frame size and connector layout assigned to this design line. It is built as Version 1, indicating the first engineering release of this variant. The controller uses Function ID Version 01, which sets the available parameter structure for its analog command configuration. It is classified as a digital AC servo drive controller. These identifiers distinguish this unit from DDS versions that use different command interfaces or current ratings.
