It is used to determine the amplitude value and the kick frequency value.
Swing relative to the center frequency (variable swing, select F7-00 as 0):
Swing (AW) =frequency source F0-01 setup times swing amplitude F7-01.
Swing relative to the maximum frequency (fixed swing, select F7-00 as 1):
Swing (AW) = maximum frequency F0-04 times swing amplitude F7-01.
When the swing is running, the kick frequency relative to the swing= Swing
(AW) times kick frequency amplitude F7-02.
If “Swing relative to the center frequency (variable swing amplitude, select
F7-00 as 0)” is selected, the kick frequency is variable value.
If “Swing relative to the maximum frequency (fixed swing, select F7-00 as 1)”
is selected, the kick frequency is fixed value.

Swing frequency cycle: It defines the time of a whole cycle for rising and
falling of the swing frequency.
The triangle wave rising and falling time is as shown in Fig.6-22:
Triangle wave rising time= Swing frequency cycle F7-03 times triangle wave
rising time coefficient F7-04 (unit: s)
Triangle wave falling time= Swing frequency cycle F7-03 times (1-triangle
wave rising time coefficient F7-04) (unit: s)
Remark: When the inverter is running with swing frequency, if the center
frequency changes, it stops swinging until the inverter running from the
current center frequency to the changed center frequency.
Caution: When the inverter is running with swing frequency, if the center
frequency changes, it stops swinging until the inverter running from the
current center frequency to the changed center frequency.
