The R911271511 (DKR03.1-W200N-BE32-01-FW) is an industrial motor driver module by Rexroth Indramat, engineered for precise control of speed, torque, braking, and direction in automated machinery such as printing equipment. It integrates multiple sensor inputs for real-time operational monitoring and error logging. This module features a SERCOS command interface, RS232 and RS485 communication ports for remote access, an analog interface card, and incorporates a brake resistor mechanism for automatic power-down procedures. The cooling method utilizes a built-in air blower. It is designed for use with a 3-phase input and absolute grounding, though operation with ungrounded power is possible with an autotransformer. Technical features include a rigid DC bus without a bleeder, support for digital servo and resolver feedback, a rated current of 200 A, and it conforms to the DKR product series, version 03, with design and function numeric version 01.
