6.16.3.1 General
ThePIDfunctionhasbeendevelopedforgeneraluseswhichcanincludenip-roll,winders,unwinders,pressure
controlofpumpsandextruders.
Adanceroraloadcellcanbeusedasposition/tensiontransducer.
Theinputs(withtheexceptionofthoseconcerningthetransducers)andtheoutputscanbecongured,theycan
beassociatedtovariousconverterparameters.E.g.thePIDoutputcanbesenttothespeedortocurrentregulator.
Theanaloginputs/outputswillbesampled/updatedto2ms.
Thedigitalinputs/outputswillbesampled/updatedto8ms.
note! PIDfunctioninthermwarecannotbeusedwhentheAPC300cardispresent.
6.16.3.2 Inputs / Outputs
Regulation Inputs/outputs
PID source SampleparameterofFeed-forwardnormallyprogrammedonanaloginput.
PID feed-back Analoginputofposition/tensiontransducer(dancer/loadcell).
 PIDfeed-backmustbeprogrammedontheanaloginput1(terminals1-2)becauseof
theinputlterprovided.
PID offset 0  OffsetanaloginputaddedtoPID feed-back.Usedfortheadjustementofthedancerposition.
PID target Parameterassociatedwiththeregulatoroutput.Normally,itwillbeprogrammedon
thespeedreferenceofthedrive.
PID output Analogoutputoftheregulator.Usedtocarryonareferencecascadeinmultidrivessystems.
PI central v3 PID Initialvaluesettingoftheintegralcomponentoftheregulator(correspondstoinitial
diameter).Itcanbeprogrammedonananaloginput.E.g.toanultrasonictransducer
usedforthediametermeasureofawinder/unwinder.
Input Command (programmable on digital inputs)
Enable PI PID EnableofthePI(proportional-integral)oftheregulator.
Enable PD PID EnableofthePD(proportional-derivative)oftheregulator.
PI integral freeze: Freezingoftheactualvalueoftheintegralcomponentoftheregulator.
PID offset sel Offsetselect,inadditiontoPID feed-back:L=PID offset 0,H=PID offset 1.
PI central v S0  UsedwithPI central v S1 toselectoneoffourvaluesfortheinitialintegrallevel(cor-
respondingtoinitialdiameter).Throughbinaryseletion.
PI central v S1 UsedwithPI central v S0 toselectoneoffourvaluesfortheinitialintegrallevel(cor-
respondingtoinitialdiameter).Throughbinaryseletion.
Diameter calc Enableoftheinitialdiametercalculation.
Diameter calc st Stateoftheinitialdiametercalculation(digitaloutput).
