The Bosch Rexroth RAC 2 spindle drive controller, model R911256135 (RAC 2.3-250-380-A0S-W1), is an intelligent tool for controlling main spindle and frameless motors with enhanced precision and efficiency. It provides robust output stiffness and continuous power across various speed ranges, making it a reliable choice for CNC machines. The controller utilizes an internal position control loop that obtains feedback directly from the motor or spindle, ensuring accurate positioning even to the minutest fraction of a revolution. The controller operates on a 400A current and can be connected to a three-phase power supply. It features an in-built mains contactor and emergency stop switch, and efficiently feeds the regenerated energy from braking back into the power supply. It can be cooled using either internal air or a control cabinet, and houses a heat sink for removal of excess heat from its electronics. The controller, backed by a one-year Indramat USA warranty, is capable of worldwide shipping.
