The R911268722 (RAC 2.3-250-460-DP0-W1) is an AC main spindle drive controller designed for numerically controlled machine tools, supporting direct connection to a 3-phase AC power source at 400–460 V, 50/60 Hz, with ±15% voltage fluctuation and rated for 250 A current. It includes an additional encoder input for spindle or secondary motor feedback, enabling precise internal position control through a high-resolution Indramat encoder. The digital speed command utilizes a 16-bit parallel interface, allowing for extended circuit lengths and accurate low set-point operation. This controller delivers a continuous output up to 65 kW and can peak at 78 kW output. Cooling is provided by an internal blower or built-in fan located within the main controller housing. The interface terminal is X4, 25 poles. The unit is constructed to IP 10 protection standards, providing protection against solid particles greater than 50 mm, and weighs approximately 125 kg.
