R911277080
The R911277080 (DKR02.1-W200Z-BE32-01-FW) is an advanced digital drive controller from the DKR series, produced by Bosch Rexroth Indramat. It is designed primarily for controlling spindle and linear motors in the 2AD / ADF / 1MB series. Distinguished by its high level of control, wide speed range with constant power, and adaptability, it is air-cooled and equipped with a blower to promote efficient temperature regulation. The blower guides air across the heat sink, and the cooling system can be adjusted to meet various requirements, including internal or external air duct cooling. Functioning optimally at an ambient temperature between 5 and 45 degrees Celsius, this controller is designed to deliver 200 Amps.
With an enclosure protection level of IP 20, the R911277080 (DKR02.1-W200Z-BE32-01-FW) can be installed up to 1000 meters without nominal data derating. It is also sturdily built to withstand storage and shipping temperatures of -30 to 80 degrees Celsius. Weighing around 104 kilograms, the controller measures 440 x 1000 x 290 millimeters and comes with digital servo and resolver feedback, along with an integrated SERCOS command communication interface. Note, however, that the controller firmware needs to be separately purchased and is stored on a removable software module for easy transfer to a replacement drive if required.
