Product Description:

The DDS03.1-W050-DS13-00 drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. As a digital AC servo drive controller, it forms the interface between the supply module and the motor in multi-axis machinery, managing current, torque, and speed loops for coordinated motion on automated production lines. Its compact rack-mount format allows it to fit inside a centralized cabinet with other DDS modules for packaging, printing, and material-handling equipment.

Inside the cabinet, the controller is cooled by air from inside the control cabinet, so installation must allow unobstructed airflow to keep power devices within safe operating temperatures. Communication with the master system uses a SERCOS interface, enabling deterministic fiber-optic exchanges for synchronized multi-axis updates. The power stage supplies a continuous output of 50 A, which is the RMS phase current a connected servo motor may draw. Protection is limited to IP20, so the unit requires a closed rack to prevent accidental contact with live parts. Continuous duty is permitted at ambient temperatures from 0 to 45 °C, and installation elevation is limited to 1000 m because thinner air reduces internal convection.

For periods when the machine is de-energized, the drive may be stored or transported through a temperature range of -30 to 85 °C, allowing passive components to tolerate cold handling and heated storage areas. During operation, it interprets position data from motors equipped with digital servo feedback, so the control loop can respond with high resolution during positioning and speed regulation. This unit is designated as version 1 within the DDS03 line. The combination of rack mounting, enclosed installation, and digital feedback support makes it suitable for centralized servo systems that require coordinated axis control.
