Product Description:

The DDS02.1-W100-DS04-03-FW is a modular servo drive unit produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It pairs with compatible Indramat power supplies and motors so that machine axes can be coordinated through a standardized drive rack. Within an automated cell, the device converts motion commands from the controller into regulated three-phase output, which allows precise velocity and torque control on printing, packaging, and material-handling equipment. That behavior lets the connected motor follow commanded speed changes smoothly and maintain torque output under varying process loads. Its modular format also supports installation in multi-axis cabinets where several drives share a common power structure.

Field communication takes place over the SERCOS interface, giving the drive deterministic timing for cyclic setpoints and feedback. The power stage can supply up to 100 A of continuous current, matching medium-power motors that require fast dynamic response during acceleration and load changes. Thermal energy is removed by internal air cooling; cooling air is drawn from inside the enclosure and passed across the heat sink, so adequate cabinet airflow is required. Motor position is returned through digital servo feedback, allowing the controller to maintain accurate commutation and stable closed-loop operation. This feedback method supports precise rotor-angle tracking and consistent response during synchronized axis motion. The unit is Version 1.

The drive belongs to Line 02 and shares mechanical dimensions, connector locations, and rack bus wiring with other DDS modules in the same line. The required firmware is ordered as a separate subitem, so the control functions can be matched to the application. In operation, the unit functions as a Digital AC Servo Drive Controller and closes the current, velocity, or position loops according to SERCOS telegrams. This arrangement allows one platform to be adapted for different motion tasks without changing the base unit. The rack-based layout also keeps power and control connections organized in compact cabinet assemblies.
