The Rexroth Indramat drive controller, MPN R911269056 (DKR02.1-W300N-B), is engineered for precise control and monitoring of industrial servo motors. This device incorporates digital servo and resolver motor feedback interfaces, enabling data communication between the controller and motor. Electrical power is supplied via a three-phase mains connector, supporting a nominal current of approximately 300 A and operating at 240 V. An integral air cooling system with a built-in blower and heatsink dissipate heat during operation. The unit supports connection to a brake resistor with up to 240 kW braking energy to protect the power circuit during deceleration. Installation is specified for locations below 1000 meters altitude, within a maximum ambient operating temperature of +55°C and storage between -30°C and +80°C. The configuration is without a bleeder (brake chopper), featuring a rigid DC bus as standard for this series 02, design version 1 controller.
