The skip references functions are available to prevent continuous operation within a specified frequency range (i.e. where mechanical resonance may occur).
When SkipReference1 (01.029) = 0 Filter 1 is disabled. SkipReferenceBand1 (01.030) defines the range either side of SkipReference1 (01.029) over which
references are rejected in either direction. The actual rejection band is therefore twice that defined by SkipReferenceBand1 (01.030) with SkipReference1
(01.029) as the centre of the band. When the selected reference is within the rejection band the lower limit of the band is passed through the filter so that
reference is always less than demanded.
Filter 2 (SkipReference2 (01.031), SkipReferenceBand2 (01.032)) and Filter 3 (SkipReference3 (01.033), SkipReferenceBand3 (01.034)) operate in the
same ways as Filter 1.
If any of the filters are active (i.e. the reference is within their rejection band) ReferenceInRejectionZone (01.035) is set to 1, otherwise it is 0.
This parameter is unipolar, but the skip frequency operates at this frequency for both directions of rotation.
