designed for other frequencies separately. The motor pole value is always an even number, because
it refers to the total number of poles, not pairs of poles. The frequency converter creates the initial
setting of par. 1-39 Motor Poles based on par. 1-23
par. 1-25 Motor Nominal Speed Motor Nominal Speed
