In this way, it can prevent the automatic running of the motor under
unexpected conditions.

It is used to set the detection value of output frequency and hysteresis value
upon removing of the output action.

When the output frequency of the driver reaches the setup frequency value,
this function can be used to adjust the detection amplitude, as shown the
following figure.
