The Bosch Rexroth R911256098 (RAC 3.5-150-460-AP0-W1-220) is an AC main spindle drive controller in the RAC series, designed to interface with frameless 1MB spindle motors for continuous power output between 10 and 30 kW. It features an internal position control loop, high-resolution INDRAMAT encoder support, and allows spindle feedback through an additional encoder input. The device operates at rated voltages of 3 x AC 400 V/50 Hz ±15% or 3 x AC 460 V, with control electronics supplied at AC 230 V/50–60 Hz. Rated current is 150 A, and the unit is equipped with an internal blower for cooling. The speed command input accepts analogue ±10 V signals. Operational temperature range is 5 to 45 °C, maximum installation altitude is 1000 m, and the unit includes an integrated mains contactor and emergency-stop circuits. Interface connection is provided via an X4, 9-pole terminal. Additional bleeders are not included.
