Product Description:

The DDS02.2-A100-BE21-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It converts command pulses from a motion processor into regulated three-phase power, coordinating torque and speed on connected motors used in packaging, material handling, and other automated cells. Within an industrial control cabinet, it functions as the central actuator stage that closes the current loop and executes precise adjustments demanded by the automation host. This control method lets the paired motor respond quickly to changing load conditions during motion.

Communication with the automation host occurs over the SERCOS interface, enabling deterministic cycle times and parameter transfer through a single fiber-optic ring. The unit delivers up to 100 A of output current, so power conductors and protective devices must be rated for that continuous load. Thermal management relies on external air from outside the control cabinet. This approach draws ambient factory air across the heat sink instead of recycling warmer enclosure air. Protection against accidental contact is provided by the IP20 rating. Reliable operation is maintained from 0 to 45 °C, accommodating most indoor production environments without additional cooling hardware.

Installation altitude is limited to 1000 m above sea level so cooling capacity and dielectric spacing are not reduced by lower air density. When de-energized, the drive may be stored between -30 to 85 °C without harming its electronic assemblies. Motor position is recognized through digital servo feedback and resolver feedback, allowing one controller type to operate both high-resolution encoders and rugged resolver transducers. This flexibility supports installations that use different motor feedback devices on separate axes. The controller belongs to Line 02, which identifies this product generation within the series.
