[S0.30]: Used to limit current, so that the tripping of frequency converter is avoided. The
function is useful for loads with large inertia or sudden changes.
3 modes of current limitation control can be selected:
● [S0.30]=0: OFF.
Current limitation control will not be disabled in any case.
● [S0.30]=1: OFF at constant speed.
Current limitation control works during Acc. and Dec., but does not work at constant
speed.
● [S0.30]=3: ON at constant speed.
Current limitation control works in all cases: Acc., Dec. and constant speed.
The current regulator is a PI regulator with configurable P factor and I factor.
● The higher set value of proportion factor [S0.32], the faster the current change will
be.
● The higher set value of I factor [S0.33], the less accuracy of current suppression.
