note: Incaseitwouldbenecessarytousethedrivewithaprovisorycurrenthigherthantherated
currentofthedrive,itispossibletoincreasetheabovedescribedvalueofPIDoutscale.
Forexample,ifonewantstoobtain1.5timesthesize,onehastoset:
PID out scale =0.2x1.5=0.3
InthiscaseitisnecessarytoenablethefunctionofoverloadcontrolOverload contr”setting
correctlythevaluesOverload current,Overload time,Base current andPause Time.
Thermwareofthedrivedoesnotperformacontrolonthepolarityofthevaluesent,for
thisreason,ifitisnotnecessarytoaddresstheregulatoroutputonparameters“Unsigned”,
thensetthePIDoutputsothatitcanbepositive.
PID out. sign PID =Onlypositive
Theparameters“Unsigned”,forexamplethecurrentlimitsT current lim + andT current lim -,areindicated
inthe“List of high priority parameters“withthesymbol“U16”.
SetPI central v sel =1.
SetPI central v 1 =0
Inthisconguration,whenexecutingthetransitionOff/OnoftheparametersfortheenablingofthePIDfunc-
tion,theregulatoroutputstartsfrom0.
Ifitisnecessarytoretainthelastvaluecalculatedalsowhenthemachineisdisabled,itnecessarytouseadigital
inputprogrammedas:
Digital input xx = PI central v S0
PI central v 1 =0
Whenthedigitalinputisatalowlogiclevel(L),thelastvaluecalculatedisstored.Applyingahighlogiclevel
(H)willresetthevalue.
SetPI top lim andPI bottom lim inordertoobtainacorrectionofthePIDblockequalto100%ofitsmaxi-
mumvalue.
PI top lim =1
PI bottom lim =-1
InthiscongurationthePIDblockoutputwillbeeitherpositiveandnegative.
SettingPI top lim =0,thepositivepartisblocked.
SettingPI bottom lim =0,thenegativepartisblocked.
Thegainsofthevariouscomponentsmustbesetexperimentallywiththemachineloaded.
Itispossibletostartthetestwiththefollowingvalues:
SetPI P gain PID =10%
SetPI I gain PID =4%
SetPD P gain PID =10%
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maintaintheseparameters=0.
