Fault code
Failure type
Possible causes
Solutions
3. Input voltage is abnormal
consumption
3. Check input power
9 E.oU3
Overvoltage at constant
speed
1. Input voltage has abnormal
changes
2. Large load inertia
1. Install input reactor
2. Add suitable braking
components
10 E.LU
Bus undervoltage
Shutdown display
1. Mains voltage is low
2. Parameters are set
incorrectly
3. Shutdown prompt
1. Check mains input power
2. Check whether
parameters are correct
11 E.oL1
Motor Overload
1. Mains voltage is too low
2. Motor rated current is set
incorrectly
3. Motor stall or mutation load
is too large
4. The big car Mara
1. Check mains voltage
2. Reset rated motor current
3. Check the load, and adjust
torque boost
4. Select the appropriate
motor
12 E.oL2
Inverter overload
1. Accelerated too quickly
2. Restart the motor that is
rotating
3. Mains voltage is too low
4. Overload
1. Increase acceleration time
2. Avoid re-starting at the
state of stop
3. Check mains voltage
4. Choose the inverter with
larger power
14 E.oUT1 output phase lose
1.motor phase loss
2.module damage
1. check motor phase
2.check if module damaged
16 E.oH2
Inverter module
overheating
1. Instantaneous overcurrent
of inverter
2. Output three-phase is
interphase or shorted to
ground
3. Air duct blockage or damage
4. The ambient temperature is
too high
5. The wires or plug-ins of
dashboard loosed
6. Auxiliary power supply is
damaged, the inverter is
undervoltage
7. Straight through of power
1. See the solutions on
overcurrent
2. Re-wiring
3. Clean or replace the air
duct
4. Decrease the ambient
temperature
5. Check and reconnect
6. Seek for service
7. Seek for service
8. Seek for service
