DKR04.1-W300N-BE56-01-FW is a Bosch Rexroth Indramat digital intelligent AC drive controller in the DKR Drive Controllers series. It belongs to line series 04 and uses design version 1. The controller has a current rating of 300 and supports digital servo and resolver feedback for motor position and speed control. Its SERCOS command interface provides communication with compatible automation controls.

The drive operates from a rated three-phase AC power voltage of 400 to 480 V with a tolerance of ±10%. Its control circuitry requires 230 V AC with a tolerance of ±10%. At a 4 kHz switching frequency, it supplies a continuous current of 185 A and approximately 82 kW of continuous drive power. Peak drive current is 212 A for short-duration load demands. The unit has no bleeder or brake chopper and uses a rigid DC bus. Cooling is provided by air from a built-in blower, while total heat dissipation is 2,250 W. The controller weighs approximately 150 kg.
