Group F11: Swing Frequency, Fixed Length and Count
The swing frequency function is applied to the textile and chemical fiber fields and the applic-
ations where traversing and winding functions are required.
The swing frequency function indicates that the output frequency of the AC drive swings up
and down with the set frequency as the center. The trace of running frequency at the time
axis is shown in the following figure.
The swing amplitude is set in F11.00 and F11.01. When F11.01 is set to 0, the swing amplit-
ude is 0 and the swing frequency does not take effect.

※
This parameter is used to select the base value of the swing amplitude.
0: Relative to the central frequency (F00.09 frequency source selection)
It is variable swing amplitude system. The swing amplitude varies with the central frequency
(set frequency).
1: Relative to the maximum frequency (F00.03 maximum output frequency)
It is fixed swing amplitude system. The swing amplitude is fixed.
