Product Description:

The DKR02.1-W300N-BE11-01-FW drive controller is produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. It is used for closed-loop control of high-power servo motors in factory automation, providing regulated torque, speed, and position for machinery that requires precise motion profiles. In this role, the controller converts control commands into managed motor output so axes can follow programmed movement with consistent response. It is suited to applications that place heavy demand on servo performance during starts, stops, and continuously changing loads.

To integrate with upper-level motion processors, the unit communicates over the SERCOS interface, allowing deterministic transfer of setpoints and status words. Thermal management is handled by air cooling with a built-in blower, so cabinet ventilation requirements remain moderate even at the device's 300 A current rating. Because the DC bus is specified with no bleeder, the connected supply must absorb regenerated energy or an external brake resistor must be used when needed. Encoder signals are accepted through digital servo and resolver feedback, allowing the controller to work with high-resolution absolute encoders as well as rugged resolver transducers for real-time position monitoring. This combination of communication and feedback support allows the drive to coordinate commanded motion with measured motor response inside the same control platform.

The module is released as design version 1, part of line series 02, and uses function version 01. These identifiers distinguish the control variant and the supported function set used by the module. They identify the module revision used in the control platform and help separate it from other variants in the same family. Matching these codes helps keep the drive aligned with compatible parameter groups and diagnostic behavior in an existing system.
