Abstract
A method for controlling a machine with at least one inverter-operated electric drive unit includes determining the instantaneous mains frequency of the mains supply to the machine and a deviation of the determined mains frequency over a standard frequency of the mains supply, determining a frequency correction value for adjusting the target drive frequency at which the electric motor of the machine is operated by weighting the deviation with a factor k, the factor k being specified dynamically as a function of at least one process variable of the drive load and/or of the operated drive process, and operating the machine at the adjusted target frequency.
