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
