An ON signal is output when the output frequency becomes equal to or higher than the operation level
(E31/E36) set in the frequency detection, and the signal is turned OFF when the frequency falls below
Frequency Detection Hysteresis Width (FDT1/ FDT2) (E32).

Set-frequency-only Arrival Signal (E20, E21, E27 = 183: FDT3, 185:
FDT4)
An ON signal is output when the output frequency is within the range of the operation level (E31/E36)
set in the frequency detection, and the signal is turned OFF when the frequency is out of range.
