AfterthecompletionoftheSpeedselftune bytheDrive,thenewidentiedparametervalues(“Nw”sufx)can
becomparedwithvaluespriortotheprocedure,bybrowsingthesubsequentmenuentries.Parametersinthis
menuarereadonly.Editingofindividualparametersmustbedoneintheirspecicmenus.
Newparameterscanbeacceptedalltogetheterbyentering“Take val”afterdisablingtheDrive.Inthiscase,
priorvaluesareoverwritten.“Self tuning”canberepeated,whethervaluesfromtheprevioustrialhavebeen
acceptedornot.
note! “Take val”doesnotstorevaluesinnon-volatilememory,sovaluesarelostifDrivepower
iscycledoffandon.YouneedtoenterSave parametersintheSTARTUPorSPECFUNC-
TIONSmenutopermanentlystorevaluesinnon-volatilememory.
Incaseofextremeparameterranges,errormessagescanoccurr.Repeatexecutioninthiscase.Iftheerrormes-
sageispersistent,keepdefaultvaluesandusemanualtuningofspeedregulator(section5.3.6Manualtuning
oftheregulators).
