No output signal.
1
FDT-1
Detects inverter output frequency reaching the user set
frequency. Outputs a signal when the absolute value
(set frequency
–output frequency) < detected frequency
width/2.
When detected frequency width is 10Hz, FDT-1 output
is as shown in the graph below.
2
FDT-2
Outputs a signal when the user set frequency and
detected frequency (FDT Frequency) are equal, and
fulfills FDT-1 condition at the same time.
[Absolute value (set frequency-detected frequency) <
detected frequency width/2]&[FDT-1]
Detected frequency width is 10Hz. When the detected
frequency is set to 30Hz, FDT-2 output is as shown in
the graph below.
3
FDT-3
Outputs a signal when the Absolute value (output
frequency–operation frequency) < detected frequency
width/2.
Detected frequency width is 10Hz. When detected
frequency is set to 30Hz, FDT-3 output is as shown in
