Fault code Fault description
Possible causes
Remedy
E003
Over-current
during
deceleration
Too-fast deceleration
Increase deceleration time
Too-heavy and large-inertia
load
Add proper braking units
lower-rating controller
Replace with higher-rating
controller
E004
Over-current at
constant running
speed
Sudden change of load
Check the load
Too low input voltage
Check the input power
supply or wiring
Lower-rating controller
Replace with higher-rating
controller
E005
Over-voltage
during
acceleration
Abnormal input voltage
Check input power
Restart the motor when
instantaneous trip-off occurs
Avoid prompt restart
when trip-off
E006
Over-voltage
during
deceleration
Too-fast deceleration
Add proper braking units
Abnormal input voltage
Check input power supply
or wiring
E007
Over-voltage at
constant running
speed
Abnormal input voltage
Install proper input AC
reactor
E008
Hardware
over-voltage
Abnormal input voltage
Check input power supply
or wiring
Too-fast deceleration
Increase deceleration time
E009
Under voltage of
DC bus
Too-low input voltage
Check input power supply
or wiring
E010
Controller
overload
Too fast acceleration
Increase acceleration time
Restart the motor when
instantaneous trip-off occurs
Avoid prompt restart
when trip-off
Too-low input voltage
Check input power supply
or wiring
Too-heavy load
Replace with higher-rating
controller
