Product Description

The Rexroth DKR02.1-W300N-BE74-02-FW is a digital drive controller. DKR controllers are designed for direct three-phase mains connection. The input rating is 400 to 480 Volts AC. the output current rating of the DKR02.1-W300N-BE74-02-FW is 300 Amps. As per the type code the line for the controller is 2, the design is 1, the function numeric code is 74 and the version function numeric code is 02. The DKR02.1-W300N-BE74-02-FW is equipped with a SERCOS command communication module. DKR drives equipped with SERCOS interfaces are connected to high-ranking control units with the use of a fiber optic cables. The fiber cables need to be ordered separately. The DKR02.1-W300N-BE74-02-FW also supports digital servo and resolver feedback. The drive firmware and parameters are stored on the software module which is installed in slot U1 on the basic module. The firmware needs to be ordered separately. 

The software module can be duplicated for use on drive with similar configuration. In case of drive controller malfunction, the software module can be moved to a replacement drive. This helps to minimize the downtime caused by equipment failure as the replacement drive does not need to be programmed. Continuous output current of the DKR02.1-W300N-BE74-02-FW is 141 Amps at 4 kilohertz and 110 Amps at 8 kilohertz. The rated power dissipation at continuous current output is 1800 Watts. Weight of the IP 20 rated drive is 104 kilograms. The accessories kit with catalog number M1-RAC 3 weighs 1.7 kilograms. The controller features a blower for cooling and should be operated between 5 and 45 degrees Celsius ambient temperature. Controller operation at 55 degrees Celsius leads to 20% output derating. Controller operation at temperatures exceeding 55 degrees Celsius can lead to controller malfunction. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
