Product Description

The Rexroth DKR02.1-W300N-BA08-01-FW is a 300 Amps rated drive controller. Input rating of the digital drive controller is 400 to 480 Volts AC (three-phase, 50 to 60 Hertz). DKR controllers can be connected directly to AC input. A transformer is only required in case of a mismatch between the AC system voltage and the controller input rating. The controller can tolerate up to 10% of variation in the input voltage. Control circuitry on the DKR02.1-W300N-BA08-01- FW requires single phase 230 Volts AC input and draws 200 VA power. Peak current rating of the DKR02.1-W300N-BA08-01-FW is 212 Amps. The continuous or average current output is 141 Amps at 4 kilohertz switching frequency and 110 Amps at 8 kilohertz switching frequency. Peak power output of the DKR02.1-W300N-BA08-01-FW, as relates to the drive shaft of the motor, is 93 kilowatts.

Air blower and heat sink are built into the DKR02.1-W300N-BA08-01-FW. Motor feedback is supported through digital servo and resolver feedback. DKR controllers are available with two kinds of command interfaces including SERCOS and analog. The DKR02.1-W300N-BA08-01-FW has an analog command communication interface installed in the designated slot U1 on the basic unit of the controller. The DKR02.1-W300N-BA08-01-FW does not support a bleeder. Function numeric code of the controller is 08. The version function numeric code of the controller is 01. DKR controllers are designed for control of Rexroth Indramat motors including AC main spindle motors from the 2AD and ADF families and linear motors belonging to the LSF or LAF families. These motors are rated for 10 to 93 kilowatts of continuous output power. DKR controllers are available in different power ratings. Firmware for the controllers needs to be ordered separately from the hardware. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
