The R911259374 (RAC 2.3-150-460-A00-W1) is an AC main spindle drive controller designed for numerical machine tools. It operates with a rated connection voltage of 3 x AC 400 V at 50 Hz or 3 x AC 460 V at 60 Hz and supports a rated current of 150 A. The device receives speed command input via an analogue interface (+/- 10 V) and uses a 9-pole X4 interface terminal. It does not include an additional encoder input or bleeder. Fan-assisted internal cooling allows operation within an ambient temperature range of 5 °C to 45 °C, tolerating peaks up to 55 °C. The controller functions properly at elevations up to 1000 meters; above this altitude, torque and power decrease. The unit must operate with a maximum relative humidity of 70% in compliance with DIN 40 040 class F. Mechanical mounting accessories are provided, and due to the unit's weight of 121 kg, appropriate lifting equipment should be used. Proper cooling preparations are essential to prevent condensation.
