Itispossibletostartthetestswiththevaluesbelow:
setPI P gain PID=10%
setPI I gain PID=4%
setPD P gain PID=5%
setPD D gain PID=0%
PD D lter PID=20msec
SetPI central vsel=1
SetPI central v 1=0
Withthisconguration,whentheswitchingON/OFFoftheparametersenablingthePIDfunctioniscarriedout,
theregulatoroutputstartsfrom0.
BeforeenablingthePIDregulatorandtheloopclosingitisnecessarytocheckthematchingbetweentheset
tensionandthetensionmeasuredbytheloadingcell.
Theloadingcellhastobetunedinordertohaveananalogoutput=10Vconnectedtothemaximumtensionon
therequiredmaterial.
Withaloadedmachinestartthewinder/unwinderbysettingatensionof50%.
CheckthevaluesoftheparametersAct tension ref(0¸100%,tensionsetintheTorquewindermenu)andPid
feedback (0¸10000,loadingcellfeedbackinthePIDmenu).Thetwovaluesmustbethesame.
Ifnot,actontheparameterTension scale tillthetwoparametersreachthesamevalues.
Afterthisparameterizationhasbeencarriedout,itispossibletostartthetestswiththematerial.
