5.3.2 Checking the wiring and the auxiliary voltages

The following should be checked before switching on the device:

- Properconnectionofcables(Section4,“Wiringprocedures”)

- CompliancewithSection4.11,“Engineeringnotes”

- Whenthedevicecurrentlimitisnotsetaccordingtotheratedcurrentvalueoftheconnectedmotor,apro-

tectionthermalrelaymustbeinsertedintheupperpartoftheconverter,whichhastobescaledaccording

tothemotorratedcurrenttimes0.86.

Warning! It is not allowed to connect an external voltage on the converter output.

- Drivedisabled(disconnecttheterminal12)

- Thefollowingvoltagesmustbepresent:

 -terminal7 +10V   toterminal9

 -terminal8 -10V   toterminal9

 -terminal19 +24...30V  toterminal18

- SelecttheActual spd (rpm) parameterintheDRIVESTATUSmenu.

 -Withadisabledregulatorturnthemotorinaclockwisedirection(viewfacingtheshaft).

Thedisplayedvaluemustbepositive.

 -Ifthevaluedoesnotchangeorifwrongvaluesareshown,checkthepowersupply

andthecablingoftheencoder/tachometer.

 -Ifthedisplayedvalueisnegative,theconnectionsoftheencoderorofthetachometergenerator

mustbechanged:channelA+withA-orB+withB-oftheencoder,changetheconnections

ofthetachometersignal.

5.3.3 Basic settings of the converter

note!  Itisassumedthatthedevicehasthedefaultcongurationandisconnectedandtestedaccording

tothediagramsprovidedinsection4.8,“Standardconnectiondiagrams”.Thedefaultsetting

canbeloadedviatheLoad defaultparameterintheSPECFUNCTIONSmenu.Laoding

thisparameterwillmeanthatallmodicationscarriedoutbytheuserwillbeoverwritten.An

exceptionisrepresentedbythe Tacho scaleandSpeed parameters.Thesearenotoverwritten

whenthefactorysetvaluesareloadedanditisnotnecessarytoscaleagaintheinputsignal

ofthetachometersection.ThesameisvalidfortheSize selectionparameter.

 ThefactorysettingallowsaspeedregulationwiththecascadecurrentregulationforaDC

motor,withanindependentexcitationandprovidedwithadigitalencoder.Thedrive,inthis

case,doesnotoperatewithaVoltagecontrol.Independentlyofthedesiredconguration,itis

advisedtocarryoutallthebasicsettingsdescribedinordertoavoidpossiblemistakes.After

thecommissioningallotheravailablefunctionscanbeactivated.Theirsettingisdescribed

inthefollowingpages.

Thepossiblevaluessetforeachparametercanbefoundinsection10,“Parameterlists”.

Thefollowingsettingsmustbecarriedoutwiththedisabledconverter.

Enable drive=disabled(novoltageontheterminal12).

Seesection5.1,“Keypad”,forinformationaboutoperatingthekeypad.
