The R911276159 (DKR03.1-W100N-BE31-01-FW) is a Rexroth Indramat servo drive controller engineered for integration with AC spindle motors (2AD, ADF), linear motors (LSF, LAF), and frameless spindle motors. This unit features a rated current of 100A and supports a three-phase AC input voltage of 400 to 480V at 50 to 60Hz, with 200VA control voltage power. It utilizes a SERCOS command interface, accommodates digital servo and resolver feedback, and is constructed with an integrated mains contactor and emergency stop shutdown device. The controller does not include a bleeder resistor or brake chopper, instead relying on a rigid DC bus and active heat dissipation via a built-in air blower and heatsink. Design and function versions are marked as Version 1 for both.
