4-4 TroubleshootingFault and Alarm DisplayCodesEvent numbers for PowerFlex 750-Series faults and alarms are displayed inone of three formats.• Port 00 (Host Drive) displays the event number only. For example, Fault3 “Power Loss” is displayed as:Fault Code 3.• Ports 01 through 09 use the format PEEE, indicating port number (P) andevent number (EEE). For example, Fault 1 “Analog In Loss” on an I/Omodule installed in Port 4 is displayed as:Fault Code 4001.• Ports 10 through 14 use the format PPEEE, indicating port number (PP)and event number (EEE). For example, Fault 37 “Net IO Timeout” onPort 14 is displayed as:Fault Code 14037.Drive Fault and AlarmDescriptionsThe table below contains a list of drive-specific faults and alarms, the typeof fault or alarm, the action taken when the drive faults, the parameter usedto configure the fault or alarm (if applicable), and a description and action(where applicable).EventNo. Fault/Alarm Text TypeFaultActionConfigurationParameter0 No Entry2 Auxiliary Input Resettable CoastFault3 Power Loss Configurable P449[Power Loss Actn]4 UnderVoltage Configurable P460[UnderVltg Action]Table 4.C Drive Fault and Alarm Types, Descriptions and ActionsAutoResetYYDescription/Action(s)An auxiliary input interlock is open.The DC bus voltage remained below the P451/P454 [PwrLoss X Level] of nominal for longer than the timeprogrammed in P452/P455 [Pwr Loss X Time].If the bus voltage, P11 [DC Bus Volts] falls below the valueset in P461 [UnderVltg Level] an undervoltage conditionexists.5 OverVoltage Resettable Coast Y The DC bus voltage exceeded the maximum value.Fault7 Motor Overload Configurable P410Y An internal electronic overload trip has occurred.[Motor OL Actn]8 Heatsink OvrTemp ResettableFaultCoast Y The heatsink temperature has exceeded 100% of the drivetemperature.9 Trnsistr OvrTemp ResettableFaultCoast Y The output transistors have exceeded the maximumoperating temperature.10 DynBrake OvrTemp Alarm 1 The dynamic brake resistor has exceeded its maximumoperating temperature.12 HW OverCurrent ResettableFaultCoast Y The drive output current has exceeded the hardware currentlimit.13 Ground Fault ResettableFaultCoast Y A current path to earth ground greater than 25% of driverating has occurred.14 Ground Warning Configurable The ground current has exceeded the level set in P467[Ground Warn Lvl].15 Load Loss Configurable P441[Load Loss Action]The output torque current is below the value programmed inP442 [Load Loss Level] for a time period greater than thetime programmed in P443 [Load Loss Time].17 Input Phase Loss Configurable P462[InPhase LossActn]The DC bus ripple has exceeded a preset level.PowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
