Product Description:

The DDS02.1-W050-DS23-02 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. As a drive controller, it regulates current and velocity loops for matched servo motors so that axes in automated machinery can move with commanded profiles. In multi-axis equipment, this closed-loop control helps maintain stable motion during acceleration, deceleration, and positioning. The module belongs to line 02 within the product range and is intended for mid-power automation tasks that require coordinated motion over a deterministic fieldbus.

Accessible motion commands are exchanged through the factory-installed SERCOS interface, ensuring time-synchronized data exchange between the controller and the master. The power stage is rated for a continuous output of 50 A, which is the maximum motor phase current the unit can deliver under nominal cooling. The housing has an IP20 rating, so the controller must be installed inside an electrical enclosure. Heat is removed with internal cabinet air cooling, meaning airflow drawn from within the control cabinet passes over the heat sink without external ducts. Because the cooling air is taken from the cabinet interior, the enclosure must dissipate the drive's waste heat. Reliable operation is permitted at ambient temperatures from 0–45 °C, which suits standard shop-floor environments without additional conditioning.

Feedback from the motor is processed through digital servo feedback, enabling fine position resolution without analog conversion errors. The controller maintains full output up to an elevation of 1000 m, so derating is unnecessary for most factory sites. When machinery is powered down, the unit can be stored safely between -30 to 85 °C, which supports storage in standard indoor warehouse areas. The unit is version 1, so its connectors and diagnostic behavior remain consistent within that release.
