If
the set frequency is within the frequency ju mp ra nge, th e actual
running frequency is the jump frequency close to the set frequency.
Setting the jump frequency helps to avoid the mechanical resonance
point of tho load.
ABC-

000 supports two jump frequencies. If both are set to
Tho
eh 0, the frequency jump function is disabled. The principle of t
jump frequencies and jump amplitude is shown in the fol lowing
