Product Description:

The DDS02.1-W050-DS48-00-FW/S100 is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series of modular servo drive units. It functions as a drive controller within multi-axis automation racks, coordinating torque, speed, and position loops for Indramat synchronous and asynchronous motors used on packaging lines, machine tools, and material-handling cells. By integrating closed-loop regulation and bus communication in a compact format, the device delivers consistent motion control while remaining accessible inside the electrical cabinet. In these systems, it serves as the regulation stage between the supply unit and the motor so commanded motion can be executed with stable current control.

The unit exchanges process data through the SERCOS interface, allowing deterministic fiber-optic networking between drives and central PLCs. A continuous output capability of 50 A allows the controller to supply high motor current without thermal derating during normal operation. Thermal stability is maintained by air from inside the control cabinet, so no external ducting is required when the mounting bay already provides forced convection. Rotor position is returned through digital servo feedback, enabling high-resolution commutation, accurate loop closure, and stable response during speed changes. The unit is classified as a Digital AC servo drive controller, with the power stage, signal processor, and parameter memory combined in one module.

The drive belongs to Line 02 and is Version 1. It is supplied with a separate firmware subitem, so the application feature set can be selected without changing the hardware. The module uses shared connector pinouts, wiring rules, and diagnostic codes across the platform, which keeps integration consistent in cabinets with multiple axes. Several compatible drives can therefore be installed side by side with the same control structure.
