6.1 Fault and Trouble Shooting
Fault
Code
Fault Type Reason Solution
E001 IGBT module fault
1: Acceleration time is
too short
2: IGBT module
damaged
3: Malfunction caused
by 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 when
acceleration
1: Accelerate too fast
2: Input voltage is too
low
3: Inverter capacity is
too low
1:Increase acceleration time
2:Inspect the input power
supply or wiring
3:Select larger capacity
inverter
E003
Over-current when
deceleration
1: Decelerate too fast
2: Load is too heavy and
has large inertia
3: Inverter capacity is
too low
1:Increase deceleration time
2: Add suitable braking units
3: Select larger capacity
inverter
E004
Over-current at
constant running
speed
1: Sudden change of
load
2: Input voltage is too
low
3: Inverter capacity is
too low
1:Check the load
2: Inspect the input power
supply or wiring
3: Select larger capacity
inverter
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
