The Bosch Rexroth R911262748 (RAC 2.3-250-380-API-W1) is a robust and efficient main spindle drive controller primarily utilised in the operation of main spindle and frameless spindle motors. This device, commonly installed in CNC machines, is praised for its superior stiffness and extensive speed range capabilities. Proving its high level of sophistication, it includes an internal position control loop which allows for independent spindle positioning via a work signal, with a resolution of up to 1/4 millionth of a revolution. Operating on a 3-phase electric supply, the controller incorporates a mains contactor and emergency stop switch. Impressively, it's capable of DC braking during power outages and channels braking power back into the electrical supply, even during emergency stops. The controller can be installed for cooling with ambient air or via a control cabinet, and features a built-in fan operating at 400 Volts with a frequency of 50-60 Hz. Its current rating stands at 400A. Upon purchase, the device comes with a global one-year warranty.
