b4-24
Detection width of frequency
Default
0.0%
Setting Range
0.0%~100.0%(maximum frequency)
If the frequency inverter 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 diagram 5-15.

b4-25
Frequency detection value 2 (FDT2)
Default
50.00Hz
Setting Range
0.00 Hz~ maximum frequency
b4-26
Frequency detection hysteresis 2 (FDT hysteresis 2)
Default
5.0%
Setting Range
0.00~100% ((FDT2))
The frequency detection function is the same as FDT1 function. For details, refer to the descriptions of b4-22 and
b4-23.
