To determine the switching thresholds, the number of pole pairs must be taken into ac-
count: f [Hz]= (n [U/min] / 60) x number of pole pairs
Example: 5000 rev/min x 3 (number of pole pairs) / 60 = 250Hz
Asynchronous motors have a load-dependent slip between the motor speed and the ro-
tating field frequency. This must be taken into account when parameterizing the thresh-
old frequencies (fmin and fmax).
