decelerating
Potential energy load or big inertia load
Increase the brake power of external brake unit
E-06
Over-voltage
when constant speed
running
Abnormal input voltage
Check input power supply
Too short Acc/Dec time
Increase the Acc/Dec time
Abnormal change of input voltage
Install input reactor
Too big the load inertia
Connect suitable braking unit
E-07
Inverter power supply
over-voltage
Abnormal input voltage
Check input power or ask for service
E-08
Inverter overheat
Duct blockage
Clean the duct and improve ventilation condition
Ambient temperature too high
Improve ventilation condition and decrease carrier fre-
quency
Fan is broken
Change the fan
IGBT module is abnormal
Ask for help
E-09
Inverter overload
Too short Acc time
Increase the Acc time
DC braking current is too big
Reduce DC braking current and increase braking time
V/F curve is not suitable
Adjust V/F curve and torque boost value
Restart the motor when it is running
Set to restart after speed detection
Low AC power supply voltage
Check AC supply voltage
Too heavy load
Select higher power inverter
E-10
Motor overload
V/F curve is not suitable
Adjust V/F curve and torque boost value
Low AC supply voltage
Check AC supply voltage
Common motor is running with heavy load at
low speed for a long time
Please choose frequency conversion motor
Unsuitable motor overload protection coeffi-
cient
Set motor overload protection coefficient correctly
The motor is blocked or the load change too
much
Check load
E-11
Under-voltage when
running
Too low AC power supply voltage
Check AC power supply voltage
E-12
Inverter module pro-
tection
Instant over current of inverter
Refer to solution of over current
3-phase output is short together or ground short
Wiring again
Duct is blocked or fan is damaged
Clean the duct or change the fan
Ambient temperature is too high
Reduce environment temperature
Wires or connectors of control board are loose
Check and wiring again
Current waveform distorted due to output phase
loss
Check wiring
Auxiliary power is damaged and inverter volt-
age is low
Ask factory or agent for service
Abnormal control board
Ask factory or agent for service
E-13
Peripheral equipment
fault
Emergency stop terminal of peripheral equip-
ment is close
Solve the external fault and cut off the terminal
E-14
Current
Wires or connectors of control board are loose
Check and wiring again
