8.1.3 Operation modes

The operation modes of the analog input characteristic enable application-related scal-
ing as a supplement to the characteristic points mentioned above. One of the four
linear types of characteristic is selected for the signal adaptation for the analog input
signal via parameter
characteristic selected, they are corrected internally.

The analog input signal is mapped onto a reference value as a function of the charac-
teristic selected. The following examples show the operation modes for an analog

Function
The analog input signal is mapped onto the reference
value according to the points (X1/Y1) and (X2/Y2).
With a negative parameter value of the points X1 or
X2, the latter are mapped to the reference value ze-
ro.
If the points X1 or X2 have been set with a negative
parameter value or less than 0%, the input characte-
ristic is mapped to the reference value 20%.
Negative parameter values of the points Y1 or Y2 are
mapped as a positive reference value in the characte-
ristic.

Point 1:
X1 = -70.00% · 10 V = -7.00 V
Y1 = -50.00% · 50.00 Hz = -25.00 Hz
Point 2:
X2 = 80.00% · 10 V = 8.00 V
