Product Description:

The DDS02.1-W025-RS01-03-FW drive controller is produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It is used in automation cells to regulate three-phase servo motors, converting motion commands from a host controller into timed current and voltage for accurate machine-axis movement. This allows the drive to respond to changing load conditions on indexing tables, transfer axes, and similar automated systems. Its role is limited to closed-loop speed and torque regulation, while high-level path planning remains in the host control.

Communication with the central motion system is handled through the SERCOS interface, which supports deterministic cyclic data exchange over fiber-optic cabling. Thermal management uses internal air cooling, so the unit relies on airflow from inside the control cabinet instead of an external blower. The power stage provides a continuous output current of 25 A, which supports medium-torque servo motors on packaging lines, assembly gantries, and similar automated machinery. Position and velocity loops use resolver feedback to supply rotor position information for stable control across the operating range. The unit is classified as a Digital AC Servo Drive Controller for closed-loop servo operation.

The required firmware is supplied as a separate firmware subitem, so the control feature package is listed independently of the controller hardware. The controller uses Function ID 01, which keeps its parameter assignment aligned with that function group. Its hardware belongs to Line 02, so the mounting dimensions and connector locations follow that line within the series. The build carries revision 1, which identifies the controller version used for this model. These identifiers distinguish the controller variant within the product line.
