Swing Frequency ,Fixed Length and Count
The swing frequency function is applicable to the textile and
chemical fiber fields and the applications where traversing and
winding functions are required .
The swing frequency function means that the output frequency
of the inverter swings up and down with the setup frequency
(frequency command is selected by F0.07) as the center . The
trace of running frequency at the time axis is shown as the
figure above , in which the swing amplitude is set by FA.01
and FA.02 .

amplitude benchmark .

If the swing amplitude relative to the central frequency is
selected , the kick frequency is a variable value .
If the swing amplitude relative to the upper limit frequency
is selected , the kick frequency is a fixed value .

The parameter is used to determine the values of swing
amplitude and kick frequency .
Swing amplitude AW (variable swing amplitude) =
frequency source F0.07 swing amplitude FA.01x
Swing amplitude AW (fixed swing amplitude) = upper
frequency F0.11 swing amplitude FA.01x
Prompt the swing frequency is limited by the frequency
upper limit and frequency lower limit .If the setting is
inappropriate , it works abnormally .
