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.
In operation mode "11 – unipolar", the characteristic points are displaced to the origin
of the characteristics with a negative value for the X axis.

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

The change of direction of rotation is done
in the example at an analog input signal
of -1.44 V, with a tolerance band of ±0.20
V.

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
