Fault
code
Fault categories Possible reasons of fault Actions
E010
Protections of
IGBT act
Instantaneous over-current Refer to E001~E003
Short-circuit among 3-phase output or
line-to-ground short circuit
Rewiring
Vent is obstructed or fan does not work
Clean the vent or replace the fan
Over-temperature
Lower the ambient temperature
Wires or connectors of control board are loose
Check and rewiring
Current waveform distorted due to output
phase loss
Check the wiring
Auxiliary power supply is damaged or IGBT
driving voltage is too low
Seek service
Short-circuit of IGBT bridge
Seek service
Control board is abnormal Seek service
E011
IGBT module’s
heatsink
overheat
Over-temperature Lower the ambient temperature
Vent obstructed Clean the vent
Fan does not work Replace the fan
IGBT module is abnormal Seek service
E012
Rectifier’s
heatsink
overheat
Ambient over-temperature Lower the ambient temperature
Obstruction of ventilation channel Clear the ventilation channel
Fan does not work Replace the fan
E013 Drive overload
Too short Acc/Dec time
Prolong the Acc/Dec time
DC injection braking current is too big
Reduce the DC injection braking current
or prolong the braking time
Improper V/F curve
Adjust V/F curve or torque boost value
The rotating motor restart after the drive stops
instantly.
Set the starting mode (F2.00) to “start of
fly”
Low AC supply voltage
Check the AC supply voltage
Too heavy load
Select the drive with bigger power
E014 Motor over-load
Improper V/F curve
Set V/F curve and torque boost value
correctly
Low AC supply voltage Check the AC supply voltage
Common motor has operated with heavy load
at low speed for a long time.
Use a special motor if the motor is
required to operate for a long time.
Improper motor’s overload protection threshold Modify the motor’s overload protection
threshold.
Load changes fast Check the load
E015
Emergent stop
or external
equipment fails
STOP is pressed in non-panel control mode
Check the definition of STOP function in
F9.07 and the operating mode
STOP pressed when the drive is in stall status
Check the definition of STOP function in
F9.07
The drive will report E015 fault if it is in stall
status for 1 minute
Set FL.02 and FL.03 properly
Terminal used for stopping the drive in
emergent status is closed
Disconnect the terminal if the external
fault is cleared
E016
EEPROM R/W
fault
R/W fault of control parameters
Press STOP/RESET to reset
Seek service
