It is used to set the detection value of output frequency and
output the hysteresis value removed by the action .
It is used to select the running status of the inverter when the
setup frequency is lower than the frequency lower limit .
In order to avoid the motor always running with low velocity,
can be used to stop .
this function
When the output frequency of the inverter reaches the setup
frequency value , this function can be used to adjust the
detection amplitude , it is shown
