The Bosch Rexroth main spindle drive controller R911259420 (RAC 2.2-250-460-L00-Z1) provides internal position control for standalone spindle positioning. Designed for use with 3-phase AC at either 400 V (50 Hz) or 460 V (60 Hz), the unit includes an integrated heatsink and built-in fan for thermal management. The device supports parameter optimization via a standalone programming module and features an interface terminal (X4) for optical waveguides, a SERCOS interface for speed command, and a 10V speed set-point input. This AC main spindle drive controller operates at 250 A rated current, includes an additional bleeder, and is constructed for operation between 5°C and 45°C below 1000 meters elevation. It is equipped for basic protection against solid objects over 50 mm in size and has three terminals for motor power connection. No additional encoder input is present.
