Pickup Behavior and Dropout Behavior when Using a User-Defined Characteristic Curve

i

i

NOTE

The currents that are lower than the current value of the smallest characteristic-curve point do not extend
the operate time. The pickup characteristic runs in parallel to the current axis up to the smallest character-
istic-curve point. Currents that are larger than the current value of the largest characteristic-curve point do
not reduce the operate time. The pickup characteristic runs in parallel to the current axis from the largest
characteristic-curve point.

If you want to change the pickup threshold of the stage without changing all points of the characteristic curve,
you can use the additional 

Threshold (absolute)

 parameter.

You can set the 

Threshold (absolute)

 parameter to be greater than 1.1 times the 

Threshold

 value.

Then the stage behaviors are as follows:

•

The stage picks up when the measured current value exceeds the 

Threshold (absolute)

 value.

•

The stage starts dropout when the measured current value falls short of the 

Threshold (absolute)

value by 0.95 times.

•

For measured current values lower than the 

Threshold (absolute)

 value, no pickup takes place and

consequently the characteristic curve is not processed.

If you set the 

Threshold (absolute)

 parameter to be less than 1.1 times the 

Threshold

 value, the

pickup and dropout behaviors are not affected by the 

Threshold (absolute)

 parameter.

Application and Setting Notes

This stage is structured the same way as the Inverse-time overcurrent protection – advanced stage. The
only differences are described in chapter 

6.5.6.1 Description 

. This chapter provides only the application and

setting notes for setting characteristic curves and for setting the 

Threshold (absolute)

 parameter. You

can find more information on the other parameters of the stage in chapter 

6.5.5.2 Application and Setting

Notes 

.

Parameter: 

Current/time value pairs

 (from the operate curve)

With these settings, you define the characteristic curve. Set a current/time value pair for each characteristic-
curve point. The setting depends on the characteristic curve you want to realize.
