hopping point + hopping range”. The specific frequency hopping range is (frequency
hopping point - hopping range, frequency hopping point + hopping range). At most three
frequency hopping areas can be set. When the respective hopping range is 0, the
corresponding frequency hopping function will be invalid.
When the frequency hopping function is valid and the set frequency rises within the
regulation range, the final set frequency is “frequency hopping point - hopping range”; and
when the frequency hopping function drops, the final set frequency is “frequency hopping
point + hopping range”.
Multiple frequency hopping areas can be superimposed, as shown in the frequency
hopping areas 1 and 2 in Fig. 7. The final frequency hopping range is (frequency hopping
point 1 - hopping range 1, frequency hopping point 2 + hopping range 2).

Fig. 7-35 Schematic Diagram of FAR Detection
As shown in Fig. 7-35, when the multi-function output terminal or relay output is set
to “2: up to output frequency (FAR)”, and the absolute value of the difference between the
|output frequency| and |given frequency| is less than or equal to the set value of FAR
detection width (F15.20) during inverter operation, the corresponding function terminal will
output the active level. Otherwise, this terminal will output the inactive level.
