34Step 6 — Faults and Warning CodesPOWERXL DG1 SERIES ADJUSTABLE FREQUENCY DRIVES MN040012EN—December 2017 www.eaton.comFaultCode Fault Name Fault Type DefaultFault Type Possible Cause Remedy Realization11 Output PhaseSupervConfigurable Fault Current measurement has detected that there is nocurrent in one motor phaseCheck motor cable and motor DSP12 Brake ChopperSupervFault • No brake resistor installed• Brake resistor is broken• Brake chopper failureCheck brake resistor and cabling. Ifthese are OK, the chopper is faulty.Contact the distributor near youDSP13 Drive UnderTemp Configurable Warning Too low temperature measured in powerUnit’s heat sink or board. Heat sink temperature isunder –10°CDSP14 Drive OverTemp Fault Too high temperature measured in powerUnit’s heat sink or board. Heat sink temperature isover 90°C• Check the correct amount and flowof cooling air• Check the heat sink for dust• Check the ambient temperature• Make sure that the switchingfrequency is not too high inrelation to ambient temperature andmotor loadDSP15 Motor Stalled Configurable No Action Motor is stalled Check motor and load DSP16 Motor Over Temp Configurable No Action Motor is too hot, based on either the drive’s estimateor on temperature feedbackDecrease motor load. If no motoroverload exists, check the temperaturemodel parametersDSP17 Motor UnderLoadConfigurable No Action Condition defined by parameter P1.9.15~P1.9.17 havebeen valid longer than the time defined by P1.9.18Check load DSP18 IP AddressConflictConfigurable Warning IP setting issue. Check settings for IP address, verify noduplicates are on the network.MCU19 Power BoardEEPROM FaultFault Power board eeprom fault, memory lost in eeprom. Cyle power to drive. Try updatingsoftware, if issue continues contactDistributor near you.MCU20 FRAM Fault Fault FRAM data error in FRAM memory. Cycle power to drive. Try updatingsoftware, if issue contines contact aDistributor near you.MCU21 S-Flash Fault Warning Serial flash error, serial flash memory failed. Cycle power to drive. Try updatingsoftware, if issue contines contact aDistributor near you.MCU25 MCU WatchDogFaultFault Watchdog register overflows in MCU Cycle power to drive. Try updatingsoftware, if issue contines contact aDistributor near you.MCU26 Start-up Prevent Fault The time when Interlock signal activates is oversetting time.Stop drive and resend start command. MCU29 Thermistor Fault Configurable Fault Option board or control board thermistor resistor lagerthan 4.7KThermistor open or short, overtemperatureMCU32 Fan Cooling Fault Fan is damaged or stalled. Check fan and fan connected wires,verify 24Vdc is supplied to fan.DSP36 CompatibilityFaultFault The control board isn’t match with the power board. Cycle power to drive. Try updatingsoftware, if issue contines contact aDistributor near you.MCU37 Device Change Warning Power board or option card change. Alarm will reset MCU38 Device Added Warning Power board or option board added. Device is ready for use MCU39 Device Removed Fault Optional board removed from slot, or power boardremoved from control board.Device no longer available in drive. MCU40 Device Unknown Fault Unknown device connected (power board/optionboard)Check eeprom connection. MCU41 IGBT Over Temp Fault IGBT temperature is too high. • Check output loading• Check motor size• Decrease switching frequencyDSP50 AI < 4mA(4to20mA)Configurable No Action Loss in analog input signal, dropped below 4mA. Verify analog input currentreference value on either AI1 or AI2,check cabling.MCU
