Defines preset speeds 1 to 8
The preset speeds are clamped by the maximum set speed (Pr 1.06).
The preset speeds do not go back to the maximum clamp value, if the clamp (Pr 1.06) has been reduced previously.
See Pr 1.30, Pr 1.32 and Pr 1.34 description.
Three skip references are available to prevent continuous operation at a speed that would cause mechanical resonance. When a skip reference
parameter is set to 0 that filter is disabled. The skip reference band parameters define the frequency or speed range either side of the programmed
skip reference, over which references are rejected. The actual reject band is therefore twice that programmed in these parameters, the skip reference
parameters defining the centre of the band. When the selected reference is within a band the lower limit of the band is passed through to the ramps
such that reference is always less than demanded.
This parameter indicates that the selected reference is within one of the skip frequency regions such that the motor speed is not as demanded.
