Product Description:

The DDS02.1-W050-DS70-00-FW is a servo control module manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. As a digital AC servo unit, it conditions power and executes closed-loop speed and torque commands between an Indramat supply module and a compatible motor, forming a modular axis in industrial automation cells. It regulates motor current so the axis can respond to changing load conditions with stable speed and torque behavior. The controller is part of line 02, and its design supports cabinet-mounted installation where space and internal airflow can be managed inside the enclosure.

The controller handles a continuous output of 50 A, allowing it to pair with mid-power Indramat synchronous or induction motors without current derating. Command and diagnostic data move through the SERCOS interface, so drive parameters are synchronized on a real-time fiber-optic ring rather than discrete wiring. Thermal regulation relies on internal air cooling, meaning cabinet air is drawn across the heat sink and expelled through the top of the unit; external ducting is unnecessary, but the enclosure must provide adequate flow. Component durability is specified for ambient operation between 0 to 45 °C, while the housing meets IP20, so conductive parts are finger-safe but the unit is not sealed against dust carried by forced ventilation. These values affect cabinet layout, fan sizing, and ambient conditions during operation.

Operation is permitted up to 1000 m above sea level, and additional derating applies above that altitude. Position and velocity information return to the drive through digital servo feedback, giving the control loop the resolution required for fast motion updates. For logistics, the drive tolerates storage temperatures from -30 to 85 °C, so unpowered spare units can be kept in non-climate-controlled warehouses. The unit is Version 1, which identifies the product revision used for this drive type.
