Product Description:

The DDS02.1-W050-DS24-04-FW drive controller is produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It functions as a digital AC servo module that converts DC bus energy into controlled three-phase output for synchronous and induction motors used in CNC stations, gantry axes, and automated assembly equipment. By processing motor feedback inside the control loop, the unit maintains commanded motion profiles during positioning, speed regulation, and load changes. Its modular format also allows it to operate beside other axes in the same rack without requiring a separate standalone power stage for each motor channel. It can be paired with compatible motors in applications that require repeatable torque delivery and smooth low-speed response.

Its continuous output limit is 50 A, enabling the controller to energize medium-frame motors during acceleration and steady operation. Command and diagnostic data move over the SERCOS interface, so cycle-synchronous updates can travel on a fiber-optic ring with other drives and the master control. Heat produced by the IGBT stage is removed through internal air cooling, which draws cabinet air across the heat sink and supports stable operation in enclosed racks. Rotor position is evaluated through digital servo feedback, allowing high-resolution velocity estimation and direct position-loop processing inside the controller. This feedback method supports accurate speed regulation over a wide operating range and improves response to load disturbances.

The unit is part of Line 02, which uses the mechanical dimensions and connector layout associated with second-generation DDS modules. It is Version 1 and is classified as a Digital AC Servo Drive Controller. The mechanical form factor, backplane connector, and diagnostic LED layout remain consistent with related modules, helping the controller fit cleanly into shared multi-axis installations. This arrangement supports coordinated rack integration where several drive modules operate from the same DC bus and exchange status data through the system architecture. Front access to the module keeps status indication and connection points organized within dense cabinet assemblies.
