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.

* 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.
