These parameters are used to judge whether PID feedback is lost.
If the PID feedback is smaller than the value of 10-28 and the lasting time exceeds the
value of 10-27, the AC drive reports fault PD and acts according to the selected fault
protection action.
Group 11: Swing Frequency, Fixed Length and Count
The swing frequency function is applied to the textile and chemical fiber fields and the
applications 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 11-00 and 11-01. When 11-01 is set to 0, the swing
amplitude 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 (P0-07 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 (P0-10 maximum output frequency)
It is fixed swing amplitude system. The swing amplitude is fixed.

Swing frequency amplitude 11-01
☆ 0.0% 0.0%–50.0% Jump frequency amplitude 11-02
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.
