Product Description:
The RAC1.2-150-380-A00-W1 belongs to the RAC Spindle Drive Controllers series from Bosch Rexroth Indramat. It is an AC main spindle drive controller used to regulate the rotational speed and power of machine-tool spindles, enabling coordinated cutting, drilling, or grinding operations in automated production lines. By converting fixed mains energy into variable frequency and voltage for the spindle motor, the unit supports precise closed-loop control that is essential in high-accuracy metal-removal and finishing processes. This type of controller is commonly used where spindle speed must remain stable under changing load during precision machining cycles.
The controller operates from a three-phase supply of 3 x AC 400 V at 50 to 60 Hz, which matches common factory power systems. A continuous output capability of 150 A allows the unit to drive large-frame spindle motors without current derating and maintain full torque during aggressive acceleration or deep cutting passes. Speed reference is accepted through a differential signal of ±10 V analog, which simplifies the interface with conventional CNC cards and analog motion modules. Thermal management is handled by an internal blower that circulates cabinet air across the heat-sink channels and helps preserve compact panel layouts.
The unit comes with no external bleeder resistor, so dynamic braking energy must be handled through the spindle mechanics or a separate brake module when required. It also comes without an additional encoder input and with no auxiliary communication interface, so field wiring is limited to power, the analog command signal, and the required feedback channels from the CNC. Because the connection set is limited to these essential signals, the controller fits installations that use direct analog spindle control without expanded interface hardware.
