The R911234779 (RAC 2.2-150-380-A00-Z1) is an AC main spindle drive controller from Bosch Rexroth, featuring an internal position control loop for independent spindle positioning. It operates at a rated connection voltage of 3 x AC 400 V, 50–60 Hz, and supports a rated current of 150 A. The device is equipped with a programming module, control panel, and a link circuit connection. Cooling is achieved via an internal blower and built-in fan, with an 80 mm minimum clearance required for effective heat dissipation. The controller complies with DIN VDE 0160, functions within a 5°C to 45°C ambient temperature range at up to 1000 m altitude, and provides ingress protection against objects larger than 50 mm. Motor power is connected through A1, A2, and A3 terminals, with speed command input via a 9-pole interface terminal (X4) using analogue signals (+/- 10 V).
