Speed base value TheSpeed base valueisdenedbytheunitspeciedinthefactorfunction.Itisthe
referencevalueforallspeedvalues(referencevalues,adaptivespeedregulation.)given
asapercentage,andcorrespondsto100%ofthespeed.Changingthisparameterisonly
possiblewhenthedriveisdisabled(Enable drive=Disabled).TheSpeed base value
doesnotdenethemaximumpossiblespeed,whichinsomecasescanbeformedfrom
theadditionofseveralreferencevalues.ThisisdenedwithSpeed max amount.
Full load curr TheFull load curr(FLC)parameterisdenedinAmps.Itcorrespondsto100%of
thecurrentlimit.Thesettingsforthecurrentlimitandtheoverloadfunctionarebased
onthisactivecurrentvalue.
Max out voltage Maxarmaturevoltagesuppliedfromthedrive.WhenithasbeensetasFlux reg mode
“Voltagecontrol”,Max out voltagecorrespondstothecrossoverpoint.Thisparameter
hasaninuenceontheinterventionthresholdofthe“Overvoltage”message.
Encoder Spd Res  Thisparameterallowstoachieveagreaterresolutiononthespeedreference.Itsvalue
isthereverseofthedesiredspeedresolution.Defaultandminimumvalue=1.Max
value=20.
 Setting1(defaultcondition)theresolutionis1rpm
 Setting10thespeedresolutionis0,1rpm
 Thisparametercanbeusedonlyincase,asfeedbackofthemotorspeed,itisusedan
encoderconnectedtotheEncoder2connector(XE2).TheFWofthedrivedoesnot
allowtosetEncoder Sped Res>1incasethefeedbackisdifferentfromEncoder2or
incasethefunction“Enable fbk bypass”isenabled.
 Inthesameway,theFWdoesnotallowtosetaspeedfeedbackdifferentfromEncoder
2orenablethefunction“Enable fbk bypass”incaseEncoder Spd Reshasbeenset
>1.
 Thevaluethatcanbeassignedtothe Encoder Spd Resparameter,arestronglyrelated
tothe Encoder 2 pulsesvalue.TheallowedvaluesarethoseforwhichtheratioEncoder
2 pulses/Encoder Spe Resgivesanintegerresult.
 When Encoder Spd Resis>1,itisnecessarytosetalltheparametersrepresentingthe
speedofthemotorin[rpm],multipliedtimestheEncoder Spd Resvalue.Forexample,
if Encoder Spd Res=10andthemotormaxspeedis60.4rpm,theMotor max speed
valuemustbesetto604.
 Similarly,thespeedfeedbackandspeedmeasurementsin[rpm]aredisplayedasreal
speedmultipliedtimestheEncoder Spd Resvalue.
note ! Thehigherresolutionisnormallyrequestedincaseofmotorswithlowspeed.Inanycasethe
maxspeedreferencemultipliedtimesEncoder Spd resvaluemustnotexceed7000(700.0
