Abstract
In a device and a method for operating a driven spindle in a machine tool, in particular in an injection-molding machine, at least two different drives are coupled to form a common effective drive, wherein the performance and energy consumption data for each drive are stored in the form of characteristic values or characteristic curves. To use the effective drive as optimally as possible in terms of energy, it is proposed to determine the performance requirement for the driven spindle, to determine the particular operational combination of the different drives that requires the least expenditure of energy based on the determined performance requirement and to drive the drives with the determined particular operational combination.

15. A method for operating a driven spindle in a machine tool, in particular an injection molding machine, wherein at least two different drives are coupled to form a common effective drive, comprising:
-
storing performance data for each of the at least two different drives in the form of characteristic values or characteristic curves, specifying a performance profile for the effective drive, determining a performance requirement for the driven spindle, based on the performance requirement, determining from the stored performance data an operational combination of the at least two different drives that produces the performance profile, and operating the at least two different drives with the determined operational combination. - View Dependent Claims (16, 17, 18, 19, 20, 21)
