Abstract (en)
[origin: WO2020025344A1] The invention relates to a method for controlling a machine with at least one inverter-operated electric drive unit, with the machine 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 being detected, wherein a frequency correction value for adjusting the target drive frequency at which the electric motor of the machine is operated is determined 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.
