These two parameters are respectively used to set the detection value of output frequency
and hysteresis value upon cancellation of the output. The value of P8-20 is a percentage of
the hysteresis frequency to the frequency detection value (P8-19).
The FDT function is shown in the following figure.

Function Code
P8-21
If the AC drive running frequency is within the certain range of the set frequency, the
corresponding DO terminal becomes ON.
This parameter is used to set the range within which the output frequency is detected
to reach the set frequency. The value of this parameter is a percentage relative to the
maximum frequency. The detection range of frequency reached is shown in the following
figure.
