Fault
Code
Fault Type
Possible Fault Reasons
Countermeasures
E004
The inverter
accelerating
running
overvoltage
Input voltage abnormal
Check input power supply
Accelerating time is set too short
Properly lengthen the accelerating
time
When instant stop occurs,
implement restart on all rotating
motors.
Set start method F2.00 as the
rotational speed tracking restart
function.
E005
The inverter
decelerating
running
overvoltage
Decelerating time is too short
(relative to regenerated energy)
Lengthen the decelerating time
There’s potential load or load
inertia torque is large.
Select proper energy consumption
braking parts.
E006
inverter
constant-spe
ed running
overvoltage
Input voltage abnormal
Check input power supply
Accelerating and decelerating
time is set too short.
Properly lengthen the accelerating
and decelerating time
Abnormal change occurred in
input voltage.
Install input reactor.
Load has large inertia.
Consider to adopt energy
consumption braking parts.

E008
Motor
overload
V/F curve not suitable
Correctly set V/F curve and torque
lifting.
Power grid voltage is too low.
Check power grid voltage
General motor is under long-term
low speed running with huge
load.
Special motor could be selected
for long-term low speed running.
Motor overload protection
coefficient is set incorrectly.
Correctly set the motor overload
protection coefficient
Motor blocked or sudden change
in load is too large.
Check load.
E009
Inverter
overload
Accelerating time is too short.
Lengthen the accelerating time
DC braking amount is too large.
Decrease DC braking current, and
lengthen braking time.
V/F curve is not suitable
Adjust V/F curve and torque
lifting
When instant stop occurs,
implement restart on all rotating
motors.
Set start method F2.00 as the
rotational speed tracking restart
function.
Power grid voltage is too low.
Check power grid voltage
Load is too large
Select inverter of larger power
E010
Inverter
module
protection
Instant overcurrent of the inverter See overcurrent countermeasures
Output three-phase has interface
short circuit
Or grounding short circuit.
Re-wiring.
Tunnel blocked or fan damaged. Smoothen the tunnel or change the
fan.
