The Bosch Rexroth R911262004 (RAC 2.3-250-460-L00-W1) is an AC main spindle drive controller, designed to control automation equipment, with ideal performance between temperatures of +5 to +45 ͦC and maximum tolerance up to +55 ͦC. Its primary usage is in CNC machinery for high-speed, high-precision and continuous power operations. The controller uses the SERCOS interface for real-time communication and it operates at a rated current of 400 A by directly connecting to a 3-phase AC 400~460 V power source within a 50 to 60 Hz frequency range. The unit does not come with additional bleeders but offers regenerated and peak regeneration outputs of 43 kW and 78 kW respectively. It provides a continuous output of 65 kW and peak controller output of 78 kW. The controller can function at altitudes up to 1000 m without reduction in output and has a built-in fan for cooling. It weighs around 125 kg including accessories, with a one-year warranty from Indramat USA.
