The R911280775 (RAC 3.5-100-460-AY0-W1-220) is an AC main spindle drive controller used for numeric-controlled machine tools. It provides high precision with an internal position control loop capable of a maximum resolution of 1/4,000,000th of a revolution, utilizing spindle or motor feedback and incremental encoder support. The device operates with a rated connection voltage of 3 x AC 400 V (50 Hz, ±15%) or 3 x AC 460 V, and supplies up to 100 A current. Control electronics connect via AC 230 V (50-60 Hz). It supports analogue speed command signals (+/- 10 V), has an X4, 9-pole interface terminal, includes synchronous and additional encoder inputs, and is cooled by an internal blower. The unit is designed for use at ambient temperatures from +5 to +45°C and up to 1000 m above sea level, offers lead spindle feedback functionality, and meets IP 10 and class F humidity protection ratings.
