When the setting frequency is within the range of hopping frequency, the actual running frequency will
run in closer from the hopping frequency of the setting frequency. By setting the hopping frequency,
can make the frequency converter to avoid the mechanical resonance point of load.
VD560 can be set up to two hopping frequency points, if the two hopping frequency are set to 0, then
cancel the hopping frequency function. The principle of the hopping frequency and the hopping
frequency range is as below.

The function code is used to set the hopping frequency during the process of acceleration and
deceleration is valid.
When the setting is effective and the running frequency is in the range of hopping frequency, the
actual running frequency will skip hopping frequency set boundary.
