User Manual of A90 Series Inverter 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). Output frequency Set frequency + Set frequency width Set frequency - width 0 Time Output terminal Invalid 0 Time 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. 235 Function Parameter Default Function code name Unit Attribute code description setting F15.20 Detection width of output frequency arrival (FAR) 0.00 - 50.00 Hz 2.50 ○ Invalid Valid Valid
