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 |

| |
|
| 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 |
| |
|

|
| 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 |

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 |
