P3.5.2.1.6 AI1 signal inversion
Invert the analogue signal with this parameter.
In the following examples, the analogue input signal
is used as frequency reference. The figures show
how the scaling of the analogue input signal is
changed depending on the setting of this parameter.
Selection number Selection name Description
0 Normal
No inversion. The analogue input signal value 0 %
corresponds to the o the Minimum frequency
reference and the analogue input signal value 100 %
to the MaxFreqReference.
