Application areas

The Siemens 6SN1123-1AA00-0JA1 is specifically designed for heavy-duty cutting scenarios in heavy CNC machine tools, high-power cutting spindles, heavy-duty servo axes, and primary industrial machining centers. Its primary application areas include:

• Large CNC Vertical & Horizontal Lathes: Drives the main spindles of large-scale turning centers. It reliably supplies up to 120 A of current when rough-turning heavy castings and forgings (e.g., train wheels, massive industrial flanges) with deep cutting depths.
• Wind Turbine & Steam Turbine Rotor Machining: Acts as the primary drive force in specialized heavy CNC machine tools dedicated to processing wind generator main shafts and heavy steam turbine rotors.
• Large Gantry Double-Drive Axes: Synchronistically drives the multi-ton crossbeams or heavy gantry columns along their guide rails with highly dynamic position loop responses.
