<p>A method for controlling a rotational speed of a compressor train that can be driven at an adjustable rotational speed using a drive unit, a corresponding arrangement and a compressor train with a frequency converter-guided drive unit that can drive the compressor train at an adjustable rotational speed, and a frequency converter guiding the drive unit is provided. A load value describing a dynamic torsion load in the compressor train is measured at a current rotational speed of the compressor train driven by the drive unit. The load value is compared to a predetermined limit value and, if the load value satisfies a predetermined condition relative to the predetermined limit value, the current rotational speed in the compressor train is adjusted using the drive unit. The arrangement has a detection device and a control unit, which are designed to perform the method.</p> |
