Heatsink Heatsinktemperatureoftheconverteristoohigh
 Thisalarmalwaysinitiatesthedisconnectionofthedevice10secondsafterthefailure
hasbeendetected(Latch=ON).
 Anexternalcontroller(PLC,etc.)canreadthealarmviaprogrammableoutput,RS485
orBusanditcanexecuteacontrolledstopwithina10seconddelay.

External Fault Externalfault(novoltageonterminal15)
Brake fault (Seechapter6.14.8)Theconverterwasunabletocompletethetransientphasebetween
thestartcommandandthereleasemechanicalbrakecommandwithinthetimelimitset
intheTorqueDelayparameter.
 Themechanicalbrakefeedback(Brakefbk)wasnotreceivedwithinthetimeallowed.
 Themechanicalbrakefeedback(Brakefbk)remainsfor1secondaftertheclosebrake

Overcurrent Overcurrent(short-circuit/earthfault).Theinterventionpointisdeterminedbythe
Overcurrent thr parameter.Thiscanalsobeusedasindicationofthresholdoverpass
forsystemapplications.
Field loss Tooloweldcurrent.Theinterventionpointcorrespondsto50%ofthemin.eldcur-
rentsetwiththe Flux current minparameter.Thisalarmmessageisactivewiththe
enabledconverter(Enabledrive=Enabled).
Delta frequency
Thisalarmconditionisactiveifthefrequencyofthethree-phasepowersupplytothe
driveexceedsthepositiveornegativepercentagethresholdsetviatheDelta freq thres
parameter.Thepowersupplyfrequency(50or60Hz)andthustherelativethresholdsare
automaticallycalculatedbythedriveassoonasthethree-phasepowersupplyisavailable.
SSC error FunctionalityavailablestartingfromFirmwareStandard=10.08A(TPD32-EV).
Threshold parameter:thruthisparameterispossibletosetthenumberofconsecutive
wrongdatareceivedthroughtheberopticalcablewithoutgeneratinganSSCError.
 Thealarmcausereactionofthedrive.Awarningmessagecanbeoutputviaadigital
output.Whenthedriveisdisabled,itwillnotrestartuntilthefailurehasbeencancelled.

 WhenActivity=WarningintheCONFIGURATION/Speedfbkmenuischosen,the
Enable fbk bypass parameterhastobesetas“Enabled”,otherwisethedrivereaches
anuncontrolledspeedwhichcannotbestopped.
