Product Description:

The DDS02.2-W100-BE74-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It is installed in multi-axis drive racks, where it converts command data from a motion controller into regulated three-phase power for connected motors. By executing closed-loop regulation, the unit supports precise positioning, speed control, and torque control in industrial automation cells, packaging machinery, and material-handling equipment. It is intended for servo applications that require accurate response during acceleration, steady running, and braking. This arrangement also allows several machine axes to be coordinated from a central motion system within the same rack.

The drive delivers a continuous output of 100 A, so cabinet wiring and upstream fusing must be sized for that current. Its enclosure carries an IP20 rating, which protects against accidental contact while requiring installation inside a grounded electrical cabinet. Communication with the higher-level master occurs through the SERCOS interface, providing deterministic cyclic data exchange for coordinated multi-axis motion. The electronics are cooled by air drawn from inside the control cabinet, so the resulting heat must be removed by the cabinet cooling system. Operation is permitted in ambient temperatures from 0 to 45 °C, and installation is allowed up to 1000 m above sea level without derating.

Feedback processing accepts digital servo feedback and resolver feedback, allowing the same controller type to run standard Indramat motors or legacy resolver-equipped models without external interfaces. When the plant is powered down, components can be stored between -30 to +85 °C without affecting service life. The unit is part of Line 02 and design version 2, which matches the corresponding rack power supplies and companion modules for this generation. This helps maintain consistent integration within compatible DDS rack systems.
