The R911256095 (RAC 3.5-150-460-API-W1-220) is a premium main spindle drive controller, produced by Bosch Rexroth, with a 150A current rating. It is notable for its 3 x AC and 380 ... 460V rated power electronics, and AC 220 V control electronics, both of which operate across a frequency range of 50 ... 60Hz. The controller features integrated emergency-stop and main contactors, an analogue speed set-point of +/- 10 volts, and a broad continuous power speed range. This unit also includes an additional encoder input for spindle feedback and an incremental encoder output for CNC position control. Cooled via an internally integrated fan, the controller comes with a mechanical accessories kit (M1-RAC 3), housing flanges and screws for installation. Note, hose cooling options are not included but available as optional extras. This product comes with a one-year warranty, and is distributed globally via leading logistics suppliers.
