Product Description:

The DDS03.1-W030-DS01-01 drive controller is produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. As a digital AC servo drive controller, it regulates torque, speed, and position for synchronous or induction motors used in automated machining cells, packaging lines, and material-handling axes. By converting commands from a motion processor into controlled three-phase motor output, the unit links the control layer with the mechanical load in modular multi-axis cabinets. It is intended for cabinet-mounted systems that need compact integration with neighboring axes and stable motion response during continuous production. This operating role suits equipment that must coordinate repeated moves, short cycle times, and controlled motor behavior across multiple stations.

It exchanges real-time motion data through the SERCOS interface, which maintains deterministic communication between the axis controller and connected automation hardware. The power stage is rated for a continuous output of 30 A, allowing the controller to operate mid-frame servomotors without auxiliary current-boosting hardware. The housing has an IP20 rating, so it protects against accidental finger contact but still requires installation inside a control enclosure. Thermal losses are removed by air from inside the control cabinet, and this cooling method supports operation in ambient temperatures from 0 to 45 °C. This airflow arrangement helps the drive remain suitable for dense cabinet layouts where several modules operate side by side.

For non-operating periods, storage is permitted from -30 to 85 °C, and the unit can be installed at elevations up to 1000 m above sea level without changing its basic operating characteristics. Rotor position and speed are processed through digital servo feedback from the motor encoder, allowing the drive to maintain closed-loop control during acceleration, steady running, and deceleration. The unit is assigned to Line 03 with Function ID 01 and Function ID version 01. It is listed as Version 1. These identifiers place the controller within the corresponding DDS product revision.
