The R911278728 (DKR04.1-W300N-BE23-01-FW) is a Rexroth Indramat DKR 04 series drive controller engineered for operation with LSF and LAF linear and spindle motors. It is rated for a nominal current of approximately 300 A and requires a three-phase AC input voltage of 400–480 V at 50–60 Hz. The device utilizes a SERCOS command interface and supports digital servo and resolver feedback. Cooling is achieved via an integrated air blower. The unit does not include a bleeder (brake chopper) and possesses a rigid DC bus configuration. It weighs roughly 150 kg and has a control circuit consumption of 300 VA. Firmware is not included and must be ordered separately. Parameterization is necessary during commissioning, and installation should be performed by qualified personnel due to high voltage and current levels.
