The Bosch Rexroth drive controller, MPN R911256099 (RAC 3.5-150-460-A0I-W1-220), is an AC main spindle drive designed for numerically controlled machine tools. It operates at a rated voltage of 3 x AC 400–460 V (±15%), 50/60 Hz, with a rated current of 150 A and control electronics requiring AC 230 V, 50–60 Hz. It supports an analogue speed command (+/-10 V), integrated emergency-stop circuit, and position control via auxiliary interface (incremental encoder output, X4 9-pole terminal, without additional encoder input). The unit provides internal position loop control and offers rotor position resolution up to 1/4,000,000 revolution. Operating temperature is +5 to +45 °C, allowable installation altitude is up to 1000 meters MSL, and it features internal blower cooling, complying with humidity class F and protection against objects over 50 mm.
