Fault
Code
Fault Type Reason Solution
E007
Over-voltage at
constant running
speed
1: Input voltage
abnormal
2: Load inertia is too
large
1: Install input AC reactor
2: Add suitable braking units
E008
Hardware over-
voltage
1: Input voltage
abnormal
2: Decelerate too fast
3: Load inertia is too
large
1: Inspect the input power
supply or wiring
2:Increase deceleration time
3: Add suitable braking units
E009
Under voltage of
DC bus
Input voltage is too low Inspect power grid
E010 Inverter overload
1: Accelerate too fast
2: Restart the motor
when instantaneous
trip-off occurs
3: Input voltage is too
low
4: Load is too heavy
1:Increase acceleration time
2: Avoid prompt restart when
trip-off
3: Inspect power grid
4: Select larger capacity
inverter
E011 Motor overload
1: Input voltage is too
low
2: Improper setting of
motor rated current
3: Improper motor’s
overload protection
threshold
4: Inverter capacity is
too low
1: Inspect voltage of power
grid
2: Properly setting of motor
rated current
3: Inspect load and boost the
torque
4: Select larger capacity
inverter
E012
Phase-lack of input
side
Phase-lack of R, S, T Inspect the input power
supply or wiring
E013
Phase-lack of
output side
1: There is a broken
wire in
the output cable
2: There is a broken wire
in the motor winding.
3.: Output terminals are
loose
Check the wiring and
installation
