:Skip references 1 and 2
Adjustment range : 0 to 32000 rpm
Factory setting
: 0
Two skips are available to avoid a machine running at critical
speeds. When one of these parameters is at 0, the function is
deactivated.
1.30, 1.32
and
:Skip reference bands 1 and 2
Adjustment range : 0 to 300 rpm
Factory setting
: 15 rpm
Define the skip band around the avoided speed. The total skip
will therefore equal the threshold set ± skip band. When the
reference is within the window determined in this way, the
drive will restore the speed corresponding to the lower or
upper value in the window.

:Reference in rejection zone
Adjustment range : 0 or 1
This parameter is at 1 when the selected reference is within
one of the skip reference zones.
In this case, the motor speed does not correspond to the
requested reference.
