The Indramat RAC 2 Main Spindle Drive Controller (product number: R911254294 (RAC 2.2-150-460-A0I-Z1)) is a robust and intelligent interface for controlling Indramat's asynchronous main spindle motors and frameless spindle motors. Often deployed in numerically controlled machine tools, it touts resistance to physical changes and a wide speed range. A standout feature is the internal position control loop, enabling independent positioning with impressive resolution. Other notable inclusions are an emergency stop switch, a mains contactor, and direct current braking that operates even during a power failure. This unit offers two cooling options that can be carried out without extensive modifications. If cooling outside is not an option, a hose-cooling setup can be utilized. Note that the successful integration of this product depends on consideration of operating conditions and crucial data such as mechanical and technical parameters. The device has an IP10 protection classification and comes with a one-year global warranty from Indramat USA.
