Shihlin electric SC3 Series User Manual

Digital input/ output parameter group 03
PARAMETER DESCRIPTION 97

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.

Assume inverter is fully loaded at rated value and current is 20A, set 03-23(P.62)=5% and 03-24(P.63)=0.5s,
terminal function OMD will output signal when output current is less than 20×5%=1A and exceeds 0.5s, as shown
below figure:
