Vacon 100 flow Applications Manual

P3.5.2.1.4 AI1 CUSTOM. MIN (ID 380)
Use this parameter to adjust the range of the analogue input signal between -160% and
160%.
P3.5.2.1.5 AI1 CUSTOM. MAX (ID 381)
Use this parameter to adjust the range of the analogue input signal between -160% and
160%.
For example, you can use the analogue input signal as frequency reference, and set the
parameters P3.5.2.1.4 and P3.5.2.1.5 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)
Use this parameter to invert the analogue input signal.
When the analogue input signal is inverted, 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.

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 Maxi-
mum Frequency Reference.
