The R911266846 (DKR02.1-W300N-BE37-01-FW) drive controller is a versatile Rexroth Indramat product of advanced sophistication. It's primarily used to execute intelligent motion control in industrial servo systems. This flexibility allows it to control diverse motor series including the 1MB frameless spindle, 2AD asynchronous spindle, and LSF linear spindle motors. Incorporated within the design is an integrated brake resistor, used to safeguard the controller’s power circuit during motor braking by regulating excess current. The controller uses a three-phase electrical connector to reduce harmonic current and minimize large neutral wire usage, increasing power density. The R911266846 (DKR02.1-W300N-BE37-01-FW) operates at a rated power voltage of 400 to 480 volts and a frequency of 50 to 60 hertz. It can draw up to a maximum current of 212 Amperes and the control voltage power stands at 200 Volts-Amperes. Its inbuilt data-holding battery operates best at temperatures below +55 degrees Celsius. Incorrect configuration, defective components, and wrong cable connections may compromise safety. The product ships globally with Indramat USA's one-year warranty.
