Product Description:

The DDS02.2-W100-BE78-00-FW is a drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. It is installed in multi-axis automation cabinets to command AC servo motors, providing the closed-loop functions needed for precise position, velocity, and torque regulation on production machinery and material-handling equipment. In this role, it converts regulated DC-bus power into controlled motor current while maintaining the response needed for indexing, positioning, and speed-controlled motion. The controller is intended for coordinated motion systems where several axes must respond consistently to commands from a central control platform.

This unit communicates with the machine control system through a high-speed SERCOS interface, so command values and feedback are exchanged over a synchronized optical ring. Motor phase current is available up to 100 A, allowing the controller to operate large-frame servomotors without thermal derating under normal rated conditions. Thermal energy is removed by internal air cooling; cabinet air passes through the heat sink and returns to the enclosure without external ducting. Encoder data can be processed from digital servo feedback or resolver feedback, giving the controller compatibility with different motor feedback types used across servo systems. This helps the unit fit mixed motor installations in cabinet-based automation equipment.

No operating software is factory-loaded, so the unit requires a separate firmware subitem matched to the control features needed by the application. The controller is part of Line 02 and uses Version 2 of this design within the DDS platform. It is classified as a Digital AC Servo Drive Controller, indicating support for sinusoidal commutation, field-oriented current control, and parameter-based operation over the SERCOS channel. This classification also shows that the unit is intended for closed-loop AC servo applications rather than open-loop motor control.
