The swing amplitude is set in FB-00 and FB-01. When FB-01 is set to 0, the swing amplitude
is 0 and the swing frequency does not take effect.

0
This parameter is used to select the base value of the swing amplitude.
• 0: Relative to the central frequency (F0-07 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 (F0-10 maximum output frequency)
It is xed swing amplitude system. The swing amplitude is xed.
Function Code Parameter Name Setting Range Default
FB-01 Swing frequency amplitude 0.0%–100.0% 0.0%
FB-02 Jump frequency amplitude 0.0%–50.0% 0.0%
This parameter is used to determine the swing amplitude and jump frequency amplitude.
The swing frequency is limited by the frequency upper limit and frequency lower limit.
• If relative to the central frequency (FB-00 = 0), the actual swing amplitude AW is the
calculation result of F0-07 (Frequency source selection) multiplied by FB-01.
• If relative to the maximum frequency (FB-00 = 1), the actual swing amplitude AW is the
calculation result of F0-10 (Maximum frequency) multiplied by FB-01.
Jump frequency = Swing amplitude AW x FB-02 (Jump frequency amplitude).
• If relative to the central frequency (FB-00 = 0), the jump frequency is a variable value.
• If relative to the maximum frequency (FB-00 = 1), the jump frequency is a xed value.
The swing frequency is limited by the frequency upper limit and frequency lower limit.
