= 900 mm transducer output = 10V
Φ = 450 mm transducer output = 5V
The analog input to which the sensor is connected, must be programmed as PI central V3.
The parameter PI central v sel, must be set = 3.
When Enable PI PID = disable, the value of PI central V3 is written in PI output PID and used as multiplier
factor of the feed-forward.
As previously described in the instruction book, the setting of PI output PID depends on the diameters ratio, so
the voltage signal proportional to the diameter will be automatically recalculated with the formula:
PI central V3 = (Φ
0
/ Φ
1
)
Where: Φ
0
= minimum winder diameter
Φ
1
= actual diameter
Setting resolution = 3 digits after the comma ( also if in PI central V3 are displayed only 2 digits after the
comma).

! During commissioning, it is necessary to verify that the signal coming from the sensor as
proportional to the diameter and that its maximum value is corresponding to 10V (carry out
the autotune of the analog input).
It is necessary to verify that PI top lim and PI bottom lim had been programmed
