The R911289963 (DKR02.1-W300N-BA08-01-FW) is a digital drive controller from the Rexroth DKR series, supporting a nominal current of 300 A and an input voltage range of 400–480 V AC with a tolerance of ±10%. Control circuitry operates on a single-phase 230 V AC supply. The unit provides a continuous current of 141 A at 4 kHz and 110 A at 8 kHz, with a peak current of 212 A and maximum power output of 93 kW. The device features an integrated air blower for cooling and utilizes a rigid DC bus configuration, without a brake chopper (bleeder). It supports motor feedback via digital servo and resolver, and communicates via an analog command interface. This controller is designed for compatibility with motors rated from 10 to 93 kW. Firmware is supplied separately.
