The R911280726 (DKR02.1-W300N-BE56-01-FW) is a drive controller designed for precision control of Rexroth Indramat motors including LSF/LAF linear motors, 1MB frameless spindle motors, and 2AD/ADF AC main spindle motors. It operates with a three-phase AC input of 400–480 V (±10%) and requires a single-phase AC input of 230 V for control power with a 200 VA demand. The unit supports a rated current of 300 A with a peak capability of 212 A. SERCOS interface provides the command interface, while both digital servo and resolver feedback are supported for motor feedback. Cooling is achieved via a built-in air blower; no bleeder or brake chopper is present—indicating a rigid DC bus configuration. The module is built for modularity with a functional numeric code of 56, version 01, and measures 1000 x 440 x 290 mm, weighing 104 kg. Firmware is not included and must be sourced separately.
