frequency will be the jump frequency boundary close to the frequency reference.
Setting the jump frequency helps to avoid the mechanical resonance point of the
load. These series VFD supports two jump frequencies. If both are set to 0, the
frequency jump function is disabled.

Factory Setting 50.00Hz
Setting Options 0.00~F0.10

FDT hysteresis Factory Setting 5.00%
Setting Options 0.0~100.0%
When the running frequency is higher than frequency detection value, VFD digital
output is ON if its corresponding parameter is set as function code 4 through
F6.00~F6.02. When the running frequency is lower than frequency detection value
minus FDT hysteresis, VFD digital output is OFF.
The above-mentioned parameters are detection point and OFF hysteresis.
Parameter F8.18 setting value is as the percentage of frequency detection value
F8.12.
