E005
Over-
voltage when
acceleration
1: Input voltage
abnormal
2: Restart the motor
when instantaneous
trip-off occurs
1:Inspect input power
2:Avoid prompt restart
when trip-off
E006
Over-
voltage when
deceleration
1: Decelerate too fast
2: Load is too heavy and
has large inertia
3: Input voltage
abnormal
1: Increase
deceleration time
2: Add suitable braking
units
3: Inspect input power
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 Reserved
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
