The R911264848 (DKR 3.1-W200N-BE24-00) is a three-phase drive controller from the Rexroth Indramat DKR series, designed for use in applications such as machine tools and printing machines. It operates at a rated voltage of 400 to 480 V AC (±10%) and a system frequency of 50-60 Hz, with a control voltage of 230 V AC at the same frequency and tolerance. The device features a rated current of 200 A, peak current of 141 A, and heat dissipation of 1.2 kW at peak load. It supports a power voltage frequency of 800 Hz/1600 Hz at 4 kHz/8 kHz and integrates digital servo and resolver feedback. The command interface uses SERCOS, the cooling mechanism relies on an air-cooled built-in blower, and it is manufactured without a bleeder or brake chopper, utilizing a rigid DC bus.
