TheparameterSpeed ref 1 willsetinRPMx4,so:
PID out scale=(2550x4)/8500=1.2
SetPI central v sel =1.
SetPI central v 1 =1
InabsenceofacorrectionperformedbythePIblockoftheregulator,thelinespeedreference(Feed-forward)
mustbemultipliedby1andsentdirectlytothespeedregulatorofthedrive.
Inthisapplication,theregulatorcarriesoutamonotypeproportionalcontrol.Thecorrectionwillbeindicated
inpercentage,accordingtothelinespeed,from0tothemaximum.
SetPI top limit andPI bottom limit sothat,withmax.ofthedancer(max.valueoftheanaloginput1=PID
Feed-back)andsettingtheproportionalgainofthePIblockat15%,itwillcorrespondtoanequalproportional
correctionoffeed-forward.Forthisreasonset:
PI top limit =10
PI bottom limit =0.1
SetPI P gain PID =15%
SetPI I gain PID =0%
Withthisconguration,havingacorrectionproportionaltothelinespeed,thePIblockisnotabletopositionthe
danceratspeed=0.Inordertodothedrawinginstopconditions,itisnecessarytousethePDblock.
SetPD P gain PID toavaluethatallowspositioningofthedancerwithoutlargedynamicvariations.
Forexample:
PD P gain PID =1%
Ifnecessary,usethederivativecomponentasdampingcomponentofthesystem,settingforexample:
PD D gain PID =5%
PD D lter PID =20ms
Ifnotnecessary,keeptheseparameters=0.
Ifitisnecessarytocarryoutareferencecascadeforanotherdrive,setPID output onananalogoutput,for
example:
Analog output 1 / Select output 1= PID output
(withReal FF PID =10000count,Analog output 1 =10V).
