For example, you can use the analogue input signal as frequency reference, and set these 2
parameters between 40 and 80%. In these conditions, the frequency reference changes
between the Minimum frequency reference and the Maximum frequency reference, and the
analogue input signal changes between 8 and 16 mA.

P3.5.2.1.6 AI1 SIGNAL INVERSION (ID 387)
In the inversion on the analogue input signal, the curve of the signal becomes the opposite.
It is possible to use the analogue input signal as frequency reference. The selection of the
value 0 or 1 change scaling of the analogue input signal.

0 Normal
No inversion. The value 0% of the analogue input signal
agrees to the Minimum Frequency Reference. The value
100% of the the analogue input signal agrees to the
Maximum Frequency Reference.
