The Bosch Rexroth drive controller R911278864 (DKR02.1-W300B-BE43-02-FW) is engineered for use in digital intelligent drive systems (DIAX 04). It features an integrated auxiliary bleeder resistor for energy dissipation during deceleration, with a braking energy capacity of 240 kWs and continuous regenerated power of 43 kW. The device operates on a three-phase AC voltage of 400–480 V at 50/60 Hz, with a nominal current rating of approximately 300 A and peak output of 93 kW at 212 A. Control voltage is applied via the X10 port at AC 230 V, requiring 200 VA. Air cooling is provided by an internal blower. Command inputs are handled through the SERCOS interface, and feedback is managed with digital servo and resolver systems. Internal diagnostics are indicated through the H1 display.
