Jump frequencies
Jump bands
To avoid operating at frequencies where the mechanical system’s characteristic vibrations may cause resonance,
jump the resonant frequencies.
During jumping, there is a +/- hysteresis band associated with the jump frequency.
Output frequency
I band #3
* During acceleration/deceleration, the output frequency will not instantaneously jump from one hysteresis point
to the next once the reference frequency has passed the latter point, but will accelerate/decelerate through
the jump region.
