The Bosch Rexroth R911256156 (RAC 2.3-250-460-D0D-W1) drive controller facilitates the operation of 2AD asynchronous main spindle motors and 1MB frameless spindle motors, producing a continuous output of 65 kW at the motor output shaft. With a rated connection voltage of AC 460V, the controller operates off an AC 3 × 400-460V power source at 50/60 Hz frequency, tolerating up to ±15% inconsistency. The controller has a notable speed range and desirable stiffness; ideal for numerical machine tools. It generates a continuous output of 43 kW, with peak output of 78 kW possible for up to 5 seconds. Weighing approximately 121 kg, the controller uses control cabinet exterior air for cooling, thanks to a built-in fan, while operating comfortably between +5 to +45 ͦ C. Protected by IP10 class, which guards against large solid particles, it works best up to 1000 m above sea level. This controller can be shipped worldwide and includes a one-year warranty from Indramat USA.
