Failure type and the countermeasure
 

Failure
code
Failure type Possible reason Countermeasure
E001 overcurrent
during
accelerating
process
Improper V/F curve Adjust V/F curve setting adjust
manual torque boost or change to
automatic torque boost
Restart rotating motor Set speed checking restart function
Low power source voltage Check input power supply
Too small power of the inverter Choose inverter with high-power
Accelerating time is too short Prolong accelerating time
   
E002 overcurrent
during
decelerating
process
Have potential energy load or big
Inertia load
Increase braking power of external
energy consumption braking
subassembly
Power of inverter is a bit small Choose inverter with high-power
Decelerating time is too short Prolong decelerating time
   
E003 overcurrent
during constant
speed process
Accel/Decel time is set to too
short
Prolong accelerating decelerating
time properly
low power source voltage Check input power supply
Power of inverter is a bit small Choose inverter with high-power
Load change suddenly or
Have unwonted phenomena
Check or reduce break of the load
   
E004 overvoltage
during
accelerating
process
Accel time is set to too short Prolong accelerating time properly
Restart rotating motor Set speed checking restart function
Unwonted input voltage Check input power supply
   
E005 overvoltage
during
decelerating
process
Have potential energy load or big
inertia load
Increase braking power of external
energy consumption braking
subassembly
Decelerating time is too short Prolong decelerating time
   
E006 Overvoltage
during constant
speed process
 
Input voltage change abnormally Assemble reactor
Load inertia is a bit big Use energy consumption
subassembly
Accel/Decel time is set to too
short
Prolong accelerating decelerating
time properly
Unwonted input voltage Check input power supply
   
E007 Inverter control
power supply
overvoltage
Unwonted input voltage Check input power supply or look for
service

 

E008 Inverter
overload
DC injection braking is too big Reduce DC injection braking
current prolong braking time
improper V/F curve Adjust V/F curve and torque boost
Restart rotating motor Set speed checking restart function
power source voltage is too low check power source voltage
Load is too big Choose inverter with high-power
E009 Motor overload improper V/F curve Adjust V/F curve and torque boost
power source voltage is too low check power source voltage
General motor run at low speed
with big load
Can choose frequency conversion
motor for long time low speed run
motor overload protection factor
set incorrectly
to set motor overload protection
factor correctly
motor blocked up or load change
too suddenly and quickly
Check the load
Accel time is set to too short Prolong accelerating time
   
E010 inverter over
heating
Ambient temperature is too high Improve ventilation condition, lower
carrier frequency
Fan damaged Replace the fan

phase to phase short circuit or
earthing short circuit of output 3
phase
wiring again
Air-path blocked or fan damaged To clear air-path or replace the fan
Ambient temperature is too high Lower ambient temperature
Connecting wire or insert on
control board loose
Check and connect the wire again
Unwonted current wave caused
by missing output phase etc.
Check wiring
Assistant power supply damaged
and drive voltage lacking
Look for service from manufacturer
or agent
Unwonted control board Look for service from manufacturer
or agent
Transient overcurrent of the
inverter
Refer to countermeasure for
overcurrent
   
E014 external device
failure
Use sudden stop key
under condition of stall
Set running parameter correctly
Sudden stop terminal for external
failure closed
Open external failure terminal after
external failure is settled
use sudden stop key in
non-keypad run mode
Look up operation mode
   
E015 current
