The R911280554 (DKR02.1-W300N-BA03-01-FW) is a Rexroth DKR series drive controller, second generation, engineered for precise control of motors including the LSF, LAF, 1MB, and 2AD models. It supports both digital servo and resolver feedback systems and utilizes an analog command interface. The controller operates on AC mains voltage in the 400–480 V range, features a built-in mains contactor, integrated blower-assisted air cooling, and an emergency stop mechanism. It is configured without a bleeder (no brake chopper, rigid DC bus) and provides a nominal current output of approximately 300 A. Firmware requires a separately ordered software module for operation. The unit has a shipping weight of about 104 kg.
