10. Troubleshooting, Diagnoses and Maintenance10.1 Trips, warnings and limitsIn order to protect the AFR or VSI the principal operatingvariables are continuously monitored by the system. If oneof these variables exceeds the safety limit an error/warningmessage is displayed. In order to avoid any possiblydangerous situations, the inverter sets itself into a stop Modecalled Trip and the cause of the trip is shown in the display.“Trip”• The AFR/VSI stops immediately.• The Trip relay or output is active (if selected).• The Trip LED is on.• The accompanying trip message is displayed.• The “TRP” status indication is displayed (area D of thedisplay).Apart from the TRIP indicators there are two moreindicators to show that the inverter is in an “abnormal”situation.“Warning”• The AFR/VSI is close to a trip limit.• The Warning relay or output is active (if selected).• The Trip LED is flashing.• The accompanying warning message is displayed in window[722] Warning.• One of the warning indications is displayed (area F ofthe display).“Limits”• The AFR/VSI is limiting torque and/or frequency toavoid a trip.• The Limit relay or output is active (if selected).• The Trip LED is flashing.• One of the Limit status indications is displayed (area Dof the display).Table 17Ext tripList of trips and warningsTrip/WarningmessagesComm errorVia DigInSelectionsTrip/Off/WarnOver temp On OTOver curr FOver volt GOver voltOnOnOnUnder voltage On LVWarningindicators(Area D)Table 17Power FaultPF #### *Desat ### *DClink errorOvolt m cutOnOnOnOnOver voltage Warning VLSafe stop Warning SSTSupply errorPhase errorSync errorAutoID errorSensor errorFreq ErrorVolt ErrorList of trips and warningsOnOnOnOnOnOnOn* Refer to Table 18 regarding which Desat or Power Fault istriggered.NOTE: For VSI refer to the Instruction manul for EmotronFDU/VFX.10.2 Trip conditions, causes andremedial actionThe table later on in this section must be seen as a basic aidto find the cause of a system failure and to how to solve anyproblems that arise. An active front end and variable speeddriveare mostly just a small part of a complete VSI system.Sometimes it is difficult to determine the cause of thefailure, although the motor inverter gives a certain tripmessage it is not always easy to find the right cause of thefailure. Good knowledge of the complete drive system istherefore necessary. Contact your supplier if you have anyquestions.The AFR/VSI is designed in such a way that it tries to avoidtrips by limiting torque, overvolt etc.Failures occurring during commissioning or shortly aftercommissioning are most likely to be caused by incorrectsettings or even bad connections.Failures or problems occurring after a reasonable period offailure-free operation can be caused by changes in the systemor in its environment (e.g. wear).Failures that occur regularly for no obvious reasons aregenerally caused by Electro Magnetic Interference. Be surethat the installation fulfils the demands for installationstipulated in the EMC directives. See chapter 7. page 25.Emotron AB 01-5076-01r1 Troubleshooting, Diagnoses and Maintenance 45
