Description
Defines speed point 2 for the load curve.
Load curve speed point 2.
Defines speed point 3 for the load curve.
Load curve speed point 3.
Defines speed point 4 for the load curve.
Load curve speed point 4.
Defines speed point 5 for the load curve.
Load curve speed point 5.
Defines speed scale value for the corresponding underload
and overload limit calculation in case user chooses to use
Linear or Quadratic predefined load curve shape.
This can be used together with parameter
limit and 79.43 Overload
Load limit speed scale.
Defines source for underload protection enable signal.

Source selection (see Terms and abbreviations
Selects the type of limit used for underload supervision.
The user has option to choose either a fixed limit, a curve of a
predefined shape or plot a custom curve as a function of
motor speed.
Fixed limit is a constant value for all the speeds.
Underload limit is calculating by formula.
I = I * (F / F )
