Operation Modes; Examples - BONFIGLIOLI Vectron Manual

6.1.3
The operation modes of the analog input characteristic enable application-related scal-
ing as a supplement to the characteristic points stated. One of the four linear types of
characteristic is selected for adaptation of the signal for the analog input signal via the
parameter
If the characteristic points are not suited for the type of characteristic selected, the
characteristic points are corrected internally.
Further information on the operation modes stated in the table can be found in the
following chapter "Examples".
6.1.3.1
The analog input signal is mapped onto a reference value as a function of the charac-
teristic. The following examples show the operation modes for an analog voltage sig-
nal. The parameter
teristic point 100% for the Y-axis corresponds to the parameter
419 of 50.00 Hz in the examples.
Attention! The various operation modes change the input characteristic as a function
In operation mode "1 – bipolar", the characteristic of the analog input can be freely
set by stating two characteristic points.

The analog input signal is mapped onto the reference
figure according to the characteristic points (X1/Y1)
and (X2/Y2).
With a negative parameter value of the characteristic
points X1 or X2, they are mapped to the reference
value zero.
If the characteristic points X1 or X2 have been set
with a negative parameter figure or smaller than 0%,
the input characteristic is mapped to the reference
value 20%.
Negative parameter values of the characteristic points
Y1 or Y2 are mapped as a positive reference value in
the characteristic.

Characteristic point 1:
X1 = -70.00% · 10 V = -7.00 V
Y1 = -50.00% · 50.00 Hz = -25.00 Hz
Characteristic point 2:
X2 = 80.00% · 10 V = 8.00 V
Y2 = 85.00% · 50.00 Hz = 42.50 Hz
