AKD Installation | 9 SetupFault Message/Warning Cause Remedy439 Following error (user). Motor did not follow commandvalues.450 Following error (presentation). Motor did not follow commandvalues.501 Bus over voltage. Bus voltage too high. Usually,this problem is load related.502 Bus under voltage.Warning issued prior to fault.503 Bus capacitor overload.504 to518Warning issued prior to fault.Internal supply voltage faultBus voltage below thresholdvalue.Single phase AC input on a driveonly rated for three-phase inputor excessive single-phasepower load.Internal supply voltage faultdetected.Check feedback commutationsetup and tuningparameters.Check feedback commutationsetup and tuningparameters.Reduce load or changemotion profile. Check systemdynamic brake capacity;add capacity if needed.Check mains voltage.Check mains voltage.Check mains voltage.Check wiring for electromagneticcompatibility(EMC). If issue persistsexchange drive.519 Dynamic brake short circuit. Brake resistor short circuit. Dynamic brake IGBT shortcircuit. Contact technicalsupport.520 Dynamic brake overload. Brake resistor overload. Motor is being overhauledor motor is being stoppedtoo quickly.521 Dynamic brake over power.Warning issued prior to fault.Too much power stored in brakeresistor.Increase brake resistorcapacity.Either get largerbrake resistr or use DCbus sharing to dissipatepower..523 Bus over voltage FPGA Bus over voltage hard fault. Check mains voltage andcheck system dynamicbrake capacity.524 Drive foldback.Warning issued prior to fault.Maximum drive power has beenexceeded. The power has beenlimited to protect the drive.Motion requires too muchpower. Change move toreduce load on drive profile.525 Output over current. Current exceeds drive peak. Check for short or feedbackfaults.526 Current sensor short circuit. Current sensor short circuit. Restart drive. If issue persists,contact support.527 Iu current AD converter stuck. Hardware failure detected. Restart drive. If issue persists,contact support.528 Iv current AD converter stuck. Hardware failure detected. Restart drive. If issue persists,contact support.140 Kollmorgen | December 2009
