Code
Description Level Condition
5-112 K5 Contactor Critical
SoftwaredetectedfailureoftheK5coilcircuit.
• Coilamperagegreaterthan2.1A-Peakor1.1Afor10sec.
• Coilamperagegreaterthan200mawhencoilnot
commanded to operate.
• Possibleinternalcurrentsenorfaultwithinthecontroller.
5-113 MotorOverCurrent Critical Motor rms current is too high
5-114 Sensor Supply
Current
Critical 12V sensor supply current is out of range:
•
<6mAindicatesopencircuit(checkplug)
• >68mAindicatesshorttopowerorground.
5-115 Encoder Fault Critical Commutator encoder sensor data is invalid:
• Oneorbothencodersopenorshort
• Encoder frequency mismatch (noise on one channel)
• Encoder
5-117
InternalSupply Critical Oneoftheinternalsupplyvaluesisinvalid.Thedriveislikely
faulty
5-118
EnableDriveOutput Critical Enable drive output is open, short-circuited or has over-current
5-119 K5 Contact Weld Critical
Maincontactorweldfault-outputvoltageseenwhencontactor
not commanded to close.
5-120
LockedRotor Critical Lockedrotortestfailed-motorspeedistoolow(<100rpm)
whilemotorrmscurrentistoohigh(>20A)
5-121 PowerStageOff Critical Controllerpowerstagewasunexpectedlyturnedoff.Diagnose
allotherfaultsrst.Drivefaulty.
5-123 Dynamic Ref Ratio Non-Critical Dynamic reference ratio value is invalid. Diagnose all other
faultsrst.Ifpersistent,drivefaulty.
5-124 Control Fault Critical Motor speed control has detected an error - speed or position
control is faulty. Either motor didn’t turn, or encoders not
responding.
5-125 Speed Cross Fault Critical
Speedcrosserror-Eithersteeringwheelsensororsteering
motorencodoerpairsareoutofsyncwitheachother.
5-126 Motor Limits Critical Motor speed/current/frequency is too high or invalid. Noise on
commutator lines.
5-127
InternalComm Critical Internalcommunicationerror.Likelydrivefailure
5-128 CPU Fault Critical Internalcpufaultorstartuptestfailed.Diagnoseallotherfaults
rst.Likelydrivefailure.
5-129 CPUEEPROM Non-Critical EEPROMchecksumerror.Expectederroraftersoftwareupdate,
butshouldclearonreboot.Ifpersists,drivefailure.
5-130 Ctrl Temp Sensor Non-Critical Controllerpowerstagetemperaturesensorisopenorshort-
circuited
5-131 Motor Temp Sensor Non-Critical
Motortemperaturesensorisopenorshort-circuited.Checkdata
connectiontomotor.Otherwisefailedmotor.
