Frequency Arrival Signal (FAR1 to 3, FDT1 to 4, FAR1FDT1)
The inverter outputs the frequency arrival signal when the output frequency reaches the set level.
Allocate “1: FAR1 (Frequency arrival signal 1 (constant speed)),” “2: FDT1 (Over set frequency arrival
signal 1),” “21: F
AR2 (Frequency arrival signal 2),” “31: FDT2 (Over set frequency arrival signal 2),”
“72: FAR3 (Frequency arrival signal 3),” “87: FAR1FDT1 (Frequency match detection),” “183: FDT3
