Product Description:

The DDS02.1-W100-DS45-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Installed in multi-axis automation cabinets, it supplies regulated three-phase power to an attached servo motor and exchanges real-time status data with the motion controller. This arrangement supports coordinated velocity, position, and torque control in industrial machinery where several axes must respond together. Because the controller regulates motor current continuously, it can translate higher-level motion commands into stable shaft response during indexing, contouring, and speed-controlled movement.

The drive is rated for a continuous output of 100 A, so the connected power stage can support high acceleration demand without immediate thermal derating. Heat generated by switching losses is removed by air from inside the control cabinet, which means the enclosure must provide forced ventilation instead of relying on an external heatsink. Command and diagnostic data move over the SERCOS interface, allowing deterministic telegram timing for synchronized multi-axis operation. Rotor position is returned through digital servo feedback, and the serial encoder link supports automatic resolution detection during drive setup. This feedback path lets the controller monitor rotor angle and speed directly, which improves loop response during rapid changes in load.

The unit belongs to Line 02, which uses the DDS module dimensions and connector placement associated with that design line. It is Version 1, using updated gate drivers while keeping parameter memory formats compatible with earlier DDS tools. The drive can be combined with supply modules and auxiliary bleeder cards in compact multi-axis racks, and each unit keeps its own current, cooling, and communication functions within a unified slot pitch. The shared rack structure keeps wiring orderly and allows the power supply stage and braking hardware to be grouped with the motion axes in one cabinet section.
