Product Description:

The DDS03.1-W050-RS18-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed to regulate torque, speed, and position of matched servo motors, the unit receives low-level commands from machine control systems and modulates three-phase output to the motor windings. It forms the link between the central PLC and electromechanical axes in automated assembly lines, packaging machines, and material-handling cells. The controller manages the electrical output sent to the motor so commanded motion remains consistent as load conditions change. In automated equipment, this helps coordinated axes respond predictably to start, stop, and positioning commands.

It supports SERCOS interface communication, so parameter data and real-time setpoints travel over fiber-optic rings with precise timing. A continuous output current of 50 A indicates how much phase current the power stage can supply under rated conditions. Thermal buildup is limited by internal air cooling, meaning the module relies on enclosure airflow rather than an external blower. The housing meets IP20, which suits installation in closed electrical panels and protects against contact with larger solid objects. Reliable feedback is achieved through resolver feedback, which provides rotor position information for closed-loop control. The operating temperature range is 0 to 45 °C, so the drive can run in typical factory conditions without derating when ambient temperature stays within that range.

Installation limits include a maximum elevation of 1000 m, allowing full current delivery at standard plant altitudes. During transport or warehouse storage, the unit withstands temperatures from -30 to 85 °C. The product belongs to Line 03 and is version 1. These identifiers indicate the design level used for this controller. Keeping the unit within its listed altitude and temperature ranges helps support normal operation and storage conditions.
