Code
Description Level Condition
4-105
MotorOverTemp Critical Motortemperatureisabove180°C.Checkmotoror
temperaturefeedbackcircuit.
4-106 CtrlOverTemp Critical Controllerpowerstagetemperatureisabove110°C
4-108 CAN Fault Critical CAN bus communication error, typically a timeout
4-109 Current Sensor Critical Current sensor offset is too high. Current through U and V
phasespresentwhendriveisidle.Internalsensorfailure.
Replace drive.
4-111 High-Side Fault Critical High-side output short-circuit or over-current in the K4 relay
coil.
4-112 K4 Contactor Critical K4 contactor coil output short-circuit or over-current
4-113
MotorOverCurrent Critical Motor rms current is too high (>150%)
4-114 Sensor Supply Current Critical
12Vcommutatorsensorsupplycurrentistoohighortoolow.
• Motor data cable disconnected
• J5-5poweroutopenorshortedtoB-
• J5-6B-Open
4-115 Encoder Fault Critical Commutator encoder sensor data is invalid:
• Oneorbothencodersopenorshort
• Encoder frequency mismatch (noise on one channel)
• Encoder
4-116
EncoderOpen Critical Onecommutatorencoderchannelistoggling,buttheotheris
not.
4-117
InternalSupply Critical Oneoftheinternalsupplyvaluesisinvalid.Likelydrive
failure.
4-118
PwrStgWatchdog Critical Powerstagewatchdogtimeout.Diagnoseallotherfaultsrst.
Ifconditionpersists,replacedrive.
4-119 K4 Contact Weld Critical Maincontactorweldfault-unexpectedvoltageatB+input
4-121 Throttle Not Zero Critical Throttle position held outside of neutral at startup for longer
than 5sec
4-122 Motor Speed High Critical Motor speed is too high (>5500 RPM). Noise on encoder
channels.
4-125 Motor Slip Speed Critical Motor slip-speed is invalid. Motor encoders abruptly
mismatch motor phase signals. May occur on rough terrain.
4-126 Motor AC Current Critical Motor AC current is invalid
4-127 Motor Frequency Critical
Motorfrequencyisabove599Hz.Likelyadrivefailure.
4-128 CPU Fault Critical Internalcpufaultorstartuptestfailed.Reboot.Diagnoseall
otherfailuresrst.Otherwisedrivefailure.
4-129 CPUEEPROM Non-Critical EEPROMchecksumerror.Thiserrorisexpectedaftera
softwareupdate,butshouldclearonthenextbootup.Ifit
persists, the drive is defective.
4-130 Ctrl Temp Sensor Non-Critical
Controllerpowerstagetemperaturesensorisopenorshort-
circuited.Internaldrivefailure.
4-131 Motor Temp Sensor Non-Critical Motor temperature sensor is open or short-circuited
4-214
K4ContactOpen Critical Main contactor (K4) output is open
