The R911253415 (RAC 4.1-300-460-AP0-W1) is an AC main spindle drive controller designed for frameless spindle motors requiring numerical regulation and a wide speed range. It supports autonomous spindle positioning, operates on a 3 x AC 400 V (±15%, 50 Hz) or 3 x AC 460 V supply, and provides a rated current of 300 A. The unit features an analogue speed command input of ±10 V and includes a high-resolution INDRAMAT encoder input for spindle feedback. Cooling is achieved with an internal blower and built-in fan. The controller should be installed within an IP54-protected cabinet to prevent moisture ingress.
