Latch ON Thealarmisstored.Theprogrammedactions(e.g.opening
theOKrelay)areenabled.Thisstatusiskeptlatchedevenif
thefaultconditionisrestored.AResetcommandisrequired
beforearestart.
 OFF Incaseofalarm,thedriveisdisabledandtheprogrammed
functionsareenabled.Thealarmisnotlatched.Whenthe
failureisremoved,thealarmis automaticallyresetandthe
devicetriesrestarting.
Ok relay open ON Analarmcausestheopeningofthepotentialisolatedcontact
betweenterminals35and36.
 OFF Thealarm doesnotcausetheopening ofthepotentialfree
contactoftheOKrelay.
Hold off time Delaytimebetweenthealarmconditiondetectionandthealarmactivation.Ifanalarm
conditionoccursthealarmstayOFFforthe Hold off time.Whenthistimeiselapsed
andthealarmisstillpresent,thealarmactivates.
Restart time IfLatch=Offandthealarmconditionpersistsevenafterthetimedenedvia Restart
time,thealarmisstoredandnorestartispossible(Latch=OFF).
note!  InTerminalmodetoresetthefaulttheterminalsenableandstartmustbeatzerovoltage.The
occurrenceofafailureisindicatedinthedisplayofthekeypad.If“Latch”=ONisselected,
aResetcommandisnecessary.Thiscanbecarriedout,forexample,bypressingtheCANC
keyonthekeypad.Ifaseconderroroccursbeforetherstonewasreset,thetext“Multiple
failures”willappearinthedisplay.Inthiscase,aresetisonlypossibleviaFailure reset
parameterintheSPECFUNCTIONSmenu.TheresetcanbeobtainedbypressingtheE
keywithadisabledinverter.
Failure supply Failureonthesupplyvoltage.
 Itindicatesafailureontheinternalvoltageoftheregulationcircuit.Themessage“Failure
supply”occursifanenabledconverterhasnovoltageontheU2andV2terminals.If
itisofashortdurationandrestored,apossibledigitaloutputpreparedforthemessage
issettoaLowcondition.Anormalresetcanbecarriedout.
Undervoltage ACInputundervoltage.
 IncaseofanACInputvoltagewhentheregulationisenabled(Enable drive = Enabled)
themessageUndervoltageappears.Theconverterisimmediatelydisabled.Tothis
purposeaninterventionthresholdispresetviatheUndervolt thr parameter.
 Ifthealarmisnotsaved(Latch=OFF),thedrivetriestostartautomaticallyafterthe
voltagehasbeenrestored.Usingtheramp,whenthevoltageisrestored,ifthefunction
Autocaptureisactive,therampoutputissettothevaluecorrespondingtothecurrent
motorspeed.Thisavoidsspeedjumps.
Overvoltage Armatureovervoltage.Thermessageappearswhenthearmaturevoltageexceedsthe
valuesetviaMax out voltageby20%.
 Ifthealarmisnotsaved(Latch=OFF),thedrivewillattempttorestartautomatically
afterthevoltagehasbeenrestored.
 Usingtheramp,whenthevoltageisrestored,ifthefunctionAutocaptureisactive,the
rampoutputissettothevaluecorrespondingtothecurrentmotorspeed.Thisavoids
speedjumps.
Overspeed ThisalarmconditionissignalledifthespeedlimitsetintheOverspeed thrparameter
isexceeded.
