—————— Instruction manual ——————

- Choiceoftheproportionalgainforzerospeed:
TheP-gaincorrespondstoSpd=0 P gain Enable spd=0 P =Enabled
TheP-gaincorrespondstothenormalP-gain  Enable spd=0 P =Disabled
- TheP-gainatazerospeedissetviaSpd=0 P gain,whenEnable spd=0 Pisenabled.
- TheinterventionthresholdfortherecognitionofzerospeedisdeterminedwithRef 0 level.Itisexpressed
inthedimensionsetbythefactorfunction.
Adaptive of the speed regulator
note!  Theadaptiveofthespeedregulatorisfactorysetasdisabled.Itmustbeusedonlywhenthe
gainofthespeedregulatorhastogethigherthanthespeedrangeorithastobereplacedwith
anotherunit.Asfortheinteractionamongtheparametersseesection6.13.2,“Adaptivespd
reg”.
- Enableoftheadaptivewithablockeddrive.Enable spd adap=Enabled.Inthiswaythesettingsof Speed
PandSpeed Iaredisabled.
- Determineonthebasisofwhichunitthegainofthespeedregulatorhastobechanged.Itnormallydepends
onthespeed(Select adap type=Speed).
- Ifthegainhastobechangedonthebasisofanotherunit,setSelect adap type =Adapreference.Thisunitis
connectedtothedeviceasananalogvalueviaananaloginput.ForthisreasontheAdap reference variable
mustbeassignedtoananaloginput(seeinthefollowingpagesthecongurationoftheanaloginputs).
 TheotherpossibilityistoinsertAdap referenceviatheserialinterfaceoraBus.Inthiscasetheinsertion
viatheterminalstripisnotnecessary.
- EnteringAdap speed 1 andAdap speed 2 threedifferentspeedrangesareavailablewithseveralgains.
ValueexpressedasapercentageofSpeed base value andrespectivelyofthemaxvalueofAdap reference.
- With Select adap type=Speed:theoptimizationiscarriedoutasdescribedforthe“Speedregulator”.To
thispurposethefollowingpointsmustbetakenintoconsideration:
- EnterwithGen offset avaluewhichisatthebeginningoftherangetobeoptimizedbutwhichatthe
sametimeisoutsidetherangesetwithAdap joint XX.
- EnterwithGen amplitude thestep,sothatthespeedremainsinsidetherangetobeoptimized.
- Theoptimizationiscarriedoutseparatelyforeachrangeandtheparamtersoftheregulatoraresetfor
eachrangewithAdap P gain XXandAdap I gain XX.
- Aftertheoptimizationofthedifferentphaseslookoverthewholespeedrange.
- BychangingthevalueofAdap joint XXitispossibletoreducetheinstabilitiespresentinthetransients
duringthechangesfromonerangetotheother.Increasingthevaluesthetransientsareslighter.
- WithSelect adap type=Adapreference:theoptimizationdependsonthesystemanditisimpossibleto
stateherethegeneralinformationneeded.
- Whenthespeedzerologicisdisabled(factorysetting)withablockeddrivethegainsofthespeedregulator
areactive.ThesearesetviaAdap P gain 1andAdap I gain 1.Whenthespeedzerologicisenabled,the
valuessetforamotoratastoparevalid.
