Fig. 7-36 Schematic Diagram of FAR Detection
As shown in Fig. 7-36, 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.
