Product Description:

The DDS02.2-W100-BE43-02-FW belongs to the DDS Drive Controllers series manufactured by Bosch Rexroth Indramat. As a Digital AC Servo Drive Controller, it coordinates torque, speed, and position loops for synchronous and asynchronous motors used in automated machine axes. The unit is from line 02 and is designated as version 2. Within a motion system, it links to a higher-level controller through fiber-optic communication and passes closed-loop commands to a connected motor with integrated feedback. This arrangement lets the controller serve as the electrical interface between machine control logic and axis movement.

Motion commands are exchanged over the SERCOS interface, allowing deterministic cycle times and a standardized telegram structure for synchronized axis control. Thermal management relies on internal air cooling; the drive pulls cabinet air across its heat sink, so no external blower is required, although cabinet airflow must still be maintained. Current output capability reaches 100 A, which is the maximum continuous phase current available to the motor windings. Component-level protection against accidental contact is classified as IP20, so the unit must be installed inside a closed electrical cabinet. Rotor position is returned to the controller via digital servo feedback, allowing high-resolution control loops without a separate incremental encoder.

The same feedback connector can also process resolver feedback, which provides a lower-resolution but electrically rugged option for large motors or harsh-duty applications. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, and the drive can be stored unpowered from -30 to 85 °C without damage to electronic components. Installation is approved up to 1000 m above sea level before derating is required. These limits should be considered when the controller is installed in enclosed cabinets with other heat-producing equipment.
