Product Description

The DKR04.1-W400N-BE74-02-FW is a state-of-the-art drive controller for Rexroth Indramat motors. The DKR04.1-W400N-BE74-02-FW monitors and controls the operation of electrical motors. The DKR series of drive controllers support manyt different applications as they come in differing drive powers and interfaces. The DKR04.1-W400N-BE74-02-FW offers a continuous drive power of 93 kW at 4 kHz and 66 kW at 8 kHz. It uses a drive controller power voltage of 0-380 Volts. It gives off 2500 Watts of heat during operation. It comes equipped with an integrated air blower for conducting heat.

The DKR04.1-W400N-BE74-02-FW has a channel for flowing of air inside it. Overall weight of the unit is around 150 kilograms. The accessories included with the drive can increase the weight by 1 to 7 kilograms. DKR04.1-W400N-BE74-02-FW will operate well within the nominal value range if it is installed from 0 to 1000 meters above sea level. Beyond this range of altitude the nominal values can get derated. The peak current of the drive controller is 282 amperes. It operates between 50-60 Hz with a tolerance of 2 Hz up or down. It requires control voltage power of 300 VA. The continuous current of the drive reaches 210 amperes at 4 kHz and 150 amperes at 8 kHz.

The DKR04.1-W400N-BE74-02-FW can continuously regenerate power of ca. 66 kW. It needs a control voltage of 230 Volts and can also operate at 220 to 240 volts. Care should be taken to operate the DKR04.1-W400N-BE74-02-FW between 5 degree celsius to 45 degree celsius. It can also operate at 55 degree celsius with derating of 80% of nominal values. It meets the IP 20 protection category as per EN60529 / IEC529. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
