6.16.3.11 Generic PID
Drivesettings:(herebelowarereportedonlytheonesconceringthePIDfunction)
Input/output
SetAnalog input 1 asinputofthevariablewhichhastoberegulated(Feed-back).
Analog input 1 / Select input 1= PID Feed-back
SetAnalog input 2 asinputoftheoffsetsignal(PID offset 0).
Analog input 2 / Select input 2 / PID offset 0
SetDigital input 1 asinputfortheenablingofthePIblockofthePID
Digital input 1 = Enable PI PID
SetDigital input 2 asinputfortheenablingofthePDblockofthePID
Digital input 2 = Enable PD PID
Parameters
Incaseitnecessarytousetheregulatoras“GenericPID”,independentfromthefeed-forwardfunction,the
parameterFeed-fwd PID mustbesetatitsmaximumvalue.Inordertodothisitisnecessarytogothrougha
PADparameter.
SetPID source comePAD 0.
OnPID source itmustbesettheparameternumberwhichhastobeassociated,choosingitfromthelistofthe
section10.2.“List of high priority parameters”(PAD 0 hasthedecimalnumber503).
Toobtainthevalue,itmustbeaddedtothedecimalvalue8192(xedoffset):
PID source =(8192+503)=8695
SetPAD 0 =10000
(TheparameterPAD 0 issituatedinthemenu’“SpecialFunction”).
note: SettingPAD0=-10000,theoutputregulatorpolaritywillbeoverturned.
SetPID source Gain =1
SetPID target withtheparameternumberthathastobeaddressedtotheoutputregulator.
Toobtainthevalueitmustbeaddedthedecimalvalue8192.
Theparametersthatcanbeaddressedaretheonesdescribedinthelistofthesection10.2.“List of high priority
parameters”.
SetPID out scale accordingtotheparametertowhichtheregulatoroutputhasbeenaddressed.
Fromthesection10.2.“List of high priority parameters”comesoutthat:
Theparametersconcerningthespeedareexpressedas[SPD].
Forallthedrivesizes,theratedcurrentwillbe2000[CURR],so:
PID out scale=2000/max.outputPID=2000/10000=0.2
