The Bosch Rexroth R911255177 (RAC 2.2-250-460-LP0-W1) is a RAC 2 spindle drive controller, primarily used for digitally regulating Indramat asynchronous and frameless spindle motors within numerically controlled machine tools. This device is equipped with an integrated main switch and an emergency halt function. During braking operation, it sends back energy to the three-phase supply. It utilizes a heatsink to dissipively manage excess heat and an air shaft admittance for internal cooling. To optimize the motor, the system hosts programming modules with pre-stored motor parameters that are transferable to a new controller. The device, capable of withstanding up to 70% humidity, operates optimally within a 5-45 degree celsius range and incorporates an IP 10 protection class as per EN 60 529. Weighing in at 121 kg, the system runs off a rated current of 400 A and operates at 400V at 50Hz or 460V at 60Hz. It includes a one-year global warranty from Indramat USA.
