Possible cause
Set/Clear conditions
12
Controller Overcurrent
External short of phase U, V or W
motor connections.
Phase current exceeded
the current
measurement limit.
Motor parameters are mis-tuned.
Controller defective.
13
Current Sensor Fault
Leakage to vehicle frame from phase
U, V or W (short in motor stator).
Controller current
sensors hove invalid
offset reading.
Controller defective.
14
Precharge Failed
External load on capacitor bank (B+
connection terminal) that prevents the
capacitor bank from charging.
The voltage of
capacitor is low.
15
Controller Severe
Undertemp
The temperature of controller is lower
than -40
℃
.
The temperature of
controller is lower than
-40
℃
.
Controller defective.
16
Controller Severe
Overtemp
The temperature of controller exceed
95
℃
.
The temperature of
controller exceed 95
℃
.
Excessive load on vehicle.
Improper mounting of controller.
17
Sever Undervoltage
The selection of controller’s voltage
parameter is wrong.
Capacitor voltage too
low inside the
controller.
Overcurrent when start.
Battery resistance too high.
Battery disconnected while driving.
Battery fuse burn or main contact not
actuation.
18
Sever Overvoltage
The selection of controller’s voltage
parameter is wrong.
Controller’s capacitor
voltage too high.
Battery resistance too high for given
regen current.
Battery disconnected while regen
braking.
22
Controller Overtemp
Cutback
Controller is operating in an extreme
environment.
The temperature of
controller exceed 85
℃
.
Excessive load on vehicle.
Improper mounting of controller.
23
Undervoltage Cutback
The batteries need recharging.
Controller’s capacitor
voltage low.
The selection of controller’s voltage
parameter is wrong.
External oversize load lead to reduce
the battery voltage.
Battery resistance too high.
Battery loosen.
Main contact get out of, fuse burn.
24
Overvoltage Cutback
Battery voltage too high while regen
braking.
Capacitor bank voltage
exceeded the set value.
The selection of controller’s voltage
parameter is wrong.
Battery resistance too high.
