Product Description:

The DDS03.1-W030-DS09-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It works as the power and regulation module between a machine control system and a compatible Indramat servo motor, managing current, velocity, and position loops for automated axes in packaging, material-handling, and machining equipment. Installed in a control cabinet, the unit converts DC bus power into three-phase motor output while exchanging real-time motion data with higher-level automation components. This arrangement lets the controller react quickly to command changes and load disturbances during synchronized machine cycles.

Communication with the motion network uses the SERCOS interface, a fiber-optic ring that transmits setpoint and feedback data in fixed time slots for predictable updates. The drive delivers a continuous phase current of 30 A, which supports medium-power motors during acceleration and steady operation. Thermal management uses internal air cooling, so cabinet airflow must keep ambient conditions within the allowable range. Electrical parts are enclosed in an IP20 housing that helps prevent accidental contact with live conductors and requires protected mounting inside the cabinet. Rotor position is tracked through digital servo feedback, allowing the controller to calculate speed and torque with high resolution for precise closed-loop control.

The unit maintains full performance in ambient temperatures from 0 – 45 °C, which suits many industrial installations without derating. For storage or extended shutdown, the electronics remain stable from -30 – 85 °C when the product is not energized. Installation altitude is limited to 1000 m because thinner air reduces cooling effectiveness above that height. The storage range allows the unit to remain off without immediate thermal damage when moisture and condensation are controlled. The unit has Function ID version 01, which keeps the parameter set matched to the correct controller version.
