Output frequency detection range

If 03-20(P.41)=5%, SU signal will be output when output frequency falls within “5% range around target frequency”.
For example, the target frequency is set to 60Hz and 03-20(P.41)=5%, then when output frequency falls within the
range of 60±60×5%=57Hz~63Hz, SU signal will be output.

Forward/Reverse rotation output frequency detection

If 03-21(P.42)=30 and 03-22(P.43)=20, FU signal will output when forward rotation frequency exceeds 30Hz; and
when reverse rotation frequency exceeds 20Hz, FU signal will also be output.

If 03-21(P.42)=30 and 03-22(P.43)=99999 (default), FU signal will output when forward and reverse rotation
frequency exceed 30Hz.
