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).
note ! 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
