Fault Type Reason Solution
E001
Inverter
module fault
1: Acceleration time is too short
2: IGBT module damaged
3: Malfunction caused
b
y
interference
4: Grounding is not properly
1: Increase acceleration time
2: Ask for support
3: Inspect external equipment and
eliminate interference
4: Check grounding wire
E002
Over-current
during
acceleration
1: Accelerate too fast
2: Input voltage is too low
3: Drive capacity is too low
1: Increase acceleration time
2: Inspect the input power supply
or wiring
3: Select larger capacity drive
E003
Over-current
during
deceleration
1: Decelerate too fast
2: Load is too heavy and has
large inertia
3: Drive capacity is too low
1: Increase deceleration time
2: Add suitable braking units
3: Select larger capacity drive
E004
Over-current
at constant
speed
1: Sudden change of load
2: Input voltage is too low
3: Drive capacity is too low
1: Check the load
2: Inspect the input power supply
or wiring
3: Select larger capacity drive
E005
Over-voltage
during
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
during
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
E007
Over-voltage
at constant
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
1: Inspect the input power supply
or wiring
