The R911256092 (RAC 3.5-100-460-D00-W1-220) is a state-of-the-art main drive controller, specifically designed for main spindle motors, offering powerful operation for motors outputting 10-30 kW power. This versatile device supports asynchronous and 1 MB frameless spindle motors to deliver high-performance motion control, operating at a current rating of 100 A. Spatial precision within numerical control machines is ensured through a resolution of 1/4 000 000th of a single revolution. This unit operates on a 3-phase 380-460V power supply and has a 16-bit parallel digital speed set-point. There is no additional encoder input. Note that encasing the controller above 1000m sea level will result in lower output power. The device complies with DIN 40 040 standards, providing a high degree of resistance to humidity in diverse climates. Cooling can be achieved internally, externally, or through optional hose cooling. The R911256092 (RAC 3.5-100-460-D00-W1-220) is available worldwide with a one-year Indramat USA warranty.
