The Bosch Rexroth R911270867 (RAC 2.3-200-460-AP0-Z1) is a spindle drive controller specifically designed for asynchronous main spindle and frameless spindle motors, most commonly used with numerically controlled machine tools. With a current rating of 300 A, it is powered by a three-phase voltage source of either 400 V at 50 Hz or 460 V at 60 Hz and can deliver continuous motor output. The controller unit comes with an integrated easy-to-operate control panel that facilitates the input and adjustment of parameter values. It can be conveniently mounted on the control cabinet's backwall with the aid of an accompanying mechanical fitting kit. Featuring an analog speed set point with +/- 10 volts and several CNC control interfaces, this unit can function optimally between ambient temperatures of 5°C to 45°C, at altitudes up to 1000 meters above sea level without any de-rating. It also includes an internal fan for temperature regulation and boasts an IP 10 certification, thus offering protection against solid objects larger than 50mm. It comes with a one-year warranty from the purchase date.
