Product Description:

The DDS02.1-W015-DS03-02-FW drive controller is manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It is a digital AC servo drive controller in Line 02, and it provides closed-loop speed and torque control for synchronous and induction axes in automated machinery. Positioned between the plant mains supply and a servo motor, it switches three-phase power with high-frequency IGBTs so programmed motion profiles from a CNC or PLC can be reproduced accurately on the mechanical load. This arrangement lets the controller regulate motor output while supporting precise axis response during production.

The unit exchanges real-time motion data over the SERCOS interface, allowing deterministic command and diagnostic traffic on a fiber-optic ring. Thermal management relies on internal cabinet air cooling, so cabinet air moves through the heat sink without the need for external ductwork. This setup supports consistent thermal performance when the controller is mounted with the required cabinet airflow. During continuous duty, the power stage can supply 15 A of phase current. The enclosure has an IP20 rating, so it should be installed in a closed electrical cabinet while still helping prevent accidental finger contact with live parts. Approved ambient operation ranges from 0 to 45 °C under normal factory conditions.

Rotor position is transmitted through digital servo feedback, enabling accurate current vector alignment for precise torque production. Stable feedback processing helps the drive maintain smooth commutation across changing loads and speeds. The controller can be installed at elevations up to 1000 m without output derating, which suits most industrial sites. For storage or transit, it tolerates temperatures from -30 to +85 °C. These storage conditions apply when the unit is not operating.
