steering angle analog quantity is
damaged or recalibrate analog quality
Alarm of high truck speed
Check if encoder harness is poor
connected.
Over low environment temperature
Traction driver temperature is over high
and its power is limited.
Change driver
Over low environment temperature
Traction motor temperature is over high
and its power is limited.
Traction motor temperature sensor is
abnormal and please check sensor or
harness.
Traction motor speed encoder is
abnormal and please check encoder or
harness.
The input voltage connected to driver is
detected to be over high.
Charge the battery or check power
harness.
Safe protection after refreshing
procedures. it will be ok after restart the
key switch.
Low battery quantity and truck
performance is limited.
Check if the output port harness is short
circuit or open circuit(such as main
contactor, backward relay and so on).
Check power harness
Cool driver
Cool motor
Check power harness
Change precharging resistance
Driver input voltage is overlow, please
check battery voltage or check if
contactor is connected.
driver input voltage is overhigh, please
check battery voltage.
Check motor encoder and temperature
sensor harness
Overlow environment temperature
Pump driver temperature is high and its
power is limited.
