The R911284828 (DKR02.1-W300B-BE76-01-FW) is a drive controller from the Indramat DKR series, designed to operate with a 3-phase AC supply voltage of 400–480V and an AC 230V control voltage. It offers a continuous power output of 55/43 kW at a rated current of 141/110 A, with a switchable frequency between 4 and 8 kHz. The controller supports digital servo and resolver feedback for motor control, and enables communication via a SERCOS interface in the U1 slot. This unit, with air cooling provided by an integrated blower, dissipates 1,800 W of heat (1,200 W released via blower). The built-in bleeder resistor can absorb up to 240 kWs, and connections are provided for motor temperature monitoring and a holding brake. The enclosure meets IP20 protection standards, and the unit has an approximate weight of 104 kg, excluding additional components.
