Application Notes
Acceleration and deceleration are not affected by the skip frequencies.
Normal accel/decel will proceed through the band once the commanded
frequency is greater than the skip frequency. See (A) & (B) in
. This function affects only continuous operation within the band.
Skip Frequency Examples
The skip frequency will have
hysteresis so the output does not
toggle between high and low values.
Three distinct bands can be
programmed. If none of the skip
bands touch or overlap, each band
has its own high/low limit.
If skip bands overlap or touch, the
center frequency is recalculated
based on the highest and lowest band
values.
If a skip band(s) extend beyond the
max frequency limits, the highest
band value will be clamped at the
max frequency limit. The center
frequency is recalculated based on
the highest and lowest band values.
If the band is outside the limits, the
skip band is inactive.
