Product Description:

The DDS2.1-W100-DS03-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It forms the link between motion control processors and Indramat servo motors, generating regulated three-phase power that governs torque, speed, and position in automated equipment. Digital servo feedback from the motor encoder closes the loop for precise velocity and position regulation.

The controller uses internal cabinet air cooling, with forced air drawn through the enclosure to remove heat during operation. Its DC link accepts 300 V ±15% from common power supply modules, and this range keeps the intermediate circuit within safe semiconductor limits. During dynamic motion segments, the unit delivers up to 100 A of peak phase current, while the maximum continuous output remains at 60 A. When the application runs at the most demanding duty cycle, the continuous current that can still be produced during the highest allowable peak interval is 40 A. Command and diagnostic data move over the fiber-optic SERCOS interface, which supports deterministic positioning with sub-millisecond cycle times.

The 24-volt control electronics draw only 500 mA, so auxiliary supply sizing remains modest. Environmental limits include humidity up to 95% non-condensing and installation elevations not exceeding 1000 m above sea level to maintain dielectric clearances. The operating temperature window spans 0 to 45 °C, and the unit can be stored between -30 and 85 °C without performance loss. Application cabinets must meet the controller’s IP20 protection category by preventing accidental contact with live parts. Mechanical attachment uses M6 mounting screws tightened to 5 Nm, and the power bus M5 terminals are secured at 3 Nm. The design rating of 100 A matches the controller’s intended use with high-power Indramat motor families.
