The R911312791 (DKR02.1-W300N-BA09-01-FW) is a drive controller engineered by Bosch Rexroth for direct mains operation at 400–480V, supporting integration with LSF, LAF, 2AD, ADF, and 1MB motors. The unit accommodates cooling via internal air, external air, or ducting, utilizing a built-in blower. It features a digital servo and resolver feedback system, an analog command interface, and supports the connection of auxiliary cards for expanded functionality. This controller design includes no bleeder (without brake chopper, rigid DC bus) and an integrated mains contactor. Rated at approximately 300A nominal current, it supports energy recovery to the mains during braking or emergency stops.
