12
Controller Overcurrent
Motor stops working
Main connector disconnects
EM brake shutdown
Throttle invalid
Brake
Pump stops working
1.
External short of phase U,V,W
motor connections
2. Motor parameters do not match.
3. Controller malfunction
Reason
Phase current exceeds
limited current
Troubleshooting
restart the key
switch
13
Current Sensor Fault
Motor stops working
Main connector disconnects
Electromagnetic brake disconnects
Throttle invalid
Brake, Pump stops working
1.
Leakage to vehicle frame from
phase U,V, or W
2. Controller malfunction
Reason
Deviation reads out to
controller current sensor.
Troubleshooting restart the
key
switch
14
Precharge Failed
Motor stops working
Main connector disconnects
Electromagnetic brake disconnects
Throttle invalid
Brake
Pump stops working
1. External load on positive
terminal of the capacitor that
prevents the capacitor from
charging.
Reason
Key switch input voltage
failed to charge the capacitor.
Troubleshooting
Reset or
re-
input interlock switch through
VCL function precharge().
15
Controller Severe Undertemp
Motor stops working
Main contactor disconnects
Electromagnetic brake disco
nnects
Throttle failure
Brake
Pump stops working
1.
Severe controller working
environment.
Reason
Radiator temperature is
lower than -40 .
Troubleshooting
Raise the temp
above -40
, restart the key
switch or interlock switch.
16
Controller Severe Overtemp
Motor stops working
Main contactor disconnects
Electromagnetic brake disconnects
Throttle failure
Brake, pump stops working
1. Severe controller working
environment.
2. Truck overloads.
3. Incorrect controller mounting
Reason Radiator temperature
is
higher than 95 .
Troubleshooting
Drop the temp
below 95
. Restart the key
switch or interlock switch.
17
Severe Undervoltage
Driving torque reduce
1. Setup error of battery parameter.
2. Power consumption of non
controller system.
3. Too large battery impedance.
4. Battery disconnects.
5. Fuse protector disconnect, or the
main contactor disconnect.
Reason
When MOSFEET axle
working, capacitor voltage is
lower than the minimum voltage
limit.
Troubleshooting
Raise the
capacitor voltage.
