Diagram 5-14 FDT level
b4-24
Detection width of frequency
Default
50.00 Hz
Setting Range
0.00 Hz~ maximum frequency
b4-25
Frequency detection value 2 (FDT2)
Default
5.0%
Setting Range
0.0%~100.0% (FDT1 level)
The frequency detection function is the same as FDT1 function. For details, refer to the descriptions of b4-22 and
b4-23.
b4-26
Frequency detection hysteresis 2 (FDT hysteresis 2)
Default
5.0%
Setting Range
0.00~100% ((FDT2))
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.

b4-27
Any frequency reaching detection value 1
Default
50.00 Hz
Setting Range
0.00 Hz ~ maximum frequency
b4-28
Any frequency reaching detection amplitude 1
Default
0.0%
Setting Range
0.0%~100.0% (maximum frequency)
