Stage with User-Defined Characteristic Curve
Description
The User-defined characteristic curve overcurrent protection stage is only available in the advanced func-
tion type.
This stage is structured the same way as the stage with the inverse-time characteristic curve. The only differ-
ence is that you can define the characteristic curve as desired.
User-Defined Characteristic Curve
With the user-defined characteristic curve, you can define the operate curve point by point using up to 30
value pairs of current and time. The device uses linear interpolation to calculate the characteristic curve from
these values. You can also define a dropout characteristic curve if you wish.
Pickup and Dropout Behaviors with the User-Defined Characteristic Curve
When the input variable exceeds the threshold value by 1.1 times, the characteristic curve is processed.
