Fig. 7-36 Schematic Diagram of FDT Detection
As shown in Fig. 7-36, when the multi-function output terminal or relay output is set
to “3: output frequency detection FDT1” or “4: output frequency detection FDT2” and the
inverter is running:
1. If the hysteresis is positive and the |output frequency| is greater than the result of “output
frequency detection FDT1/2” (F15.21/F15.23), the corresponding function terminal will
output the active level; if the |output frequency| drops to less than the result of “output
frequency detection FDT1/2 (F15.21/F15.23) - FDT1/2 hysteresis (F15.22/F15.24)”, the
corresponding function terminal will output the inactive level; and if the |output frequency|
is within the range of (output frequency detection - hysteresis, output frequency detection),
the output level of the corresponding function terminal will remain unchanged.
