Product Description:

The DDS02.1-A150-DA07-02-FW/S002 is a digital AC servo drive controller built by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. It belongs to Line 02 and serves as the closed-loop control stage for a compatible servo axis in automated machinery. The unit receives higher-level motion commands, regulates motor current, and supervises protection functions so the driven axis can follow its programmed path with low tracking error. This operating role fits positioning systems, synchronized gantries, and spindle applications where repeatable motion and stable axis response are required.

The electrical stage supplies 150 A continuously, which is suitable for medium-power Indramat servos that must hold torque during acceleration and steady-state operation. Heat is removed by air from outside the control cabinet, so the drive depends on clean ambient airflow instead of recirculating warmer enclosure air. The electronics are intended for ambient temperatures from 0 to 45 °C, and the enclosure is rated IP20, which provides protection against accidental finger contact but does not seal against liquids. Rotor position is handled through digital servo feedback, allowing the controller to process encoder signals directly for commutation and for closed-loop speed and position control.

System integration is supported by a built-in analog interface that accepts ±10 V speed or torque commands from legacy control hardware without requiring an added fieldbus card. That input arrangement allows the drive to work with older PLC platforms and motion sources that still use analog setpoints. The drive can be installed at elevations up to 1000 m above sea level, and it can be stored or transported in temperatures from -30 to +85 °C when condensation is avoided. The unit is Version 1, which identifies the controller revision used for this model.
