Product Description:

Bosch Rexroth Indramat builds the DDS03.2-W030-BA07-01-FW as part of the DDS Drive Controllers series. This servo drive module mounts inside a control cabinet and pairs with Indramat power supplies to close the torque, speed, or position loop of connected AC servo motors in automated machinery. By converting reference commands from a higher-level control system into regulated three-phase output, the unit coordinates motion axes in packaging lines, material-handling cells, and machine tools. This arrangement lets the controller regulate motor current precisely so commanded motion profiles can be followed during acceleration, steady running, stopping, and repeated indexing cycles.

It accepts command signals through an analog interface, so velocity or torque references arrive as ±10 V levels that are sampled by the controller. The power stage delivers a continuous output of 30 A, matching medium-frame Indramat motors while staying within the module's thermal limits. Cooling is provided by internal air drawn from inside the control cabinet, which removes heat without external ducting but requires adequate panel ventilation. Because the cooling air comes from the enclosure, cabinet layout should leave a clear path around the heat sink and adjacent modules. The housing has an IP20 protection category, which provides finger-safe terminals but no protection against water. The permitted ambient temperature range is 0 to 45 °C for normal operation.

Installation height must not exceed 1000 m above sea level because lower air density reduces cooling performance. For rotor position measurement, the drive accepts both digital servo feedback and resolver feedback, which supports use with newer servo motors as well as older motor designs. This dual feedback compatibility is useful when a machine platform mixes legacy axes with newer servo packages on the same line. The Version 2 design uses a modular card structure that supports different interface options for different applications and control configurations. When powered down, storage temperatures can range from -30 to +85 °C without damaging internal components.
