Fault
code
Failure type
Possible causes
Solutions
1
E.oUP
Inverter unit U-
phase fault
1. Accelerated too quickly
2. Internal damage of the
phase IGBT
3. Malfunction caused by
interference
4. Whether Grounded well
or not
1. Increase acceleration
time
2. Seek for support
3. Check whether the
peripheral devices have
strong interference

phase fault
4
E.oC1
Overcurrent when
accelerating
1. Accelerated too quickly
2. Mains voltage is low
3. The inverter power is
small
4: Output phase loss
1. Increase acceleration
time
2. Check input power
3. Choose the inverter
with larger power
Inverter
4. Check the output
wiring
5
E.oC2
Overcurrent when
decelerating
1. Decelerated too quickly
2. Load inertia torque is
large
3. The inverter power is
small
4: Output phase loss
1. Increase deceleration
time
2. Add suitable braking
components
3. Choose the inverter
with larger power
4. Check the output
wiring
6
E.oC3
Overcurrent at
constant speed
1. Load mutation or
abnormal
2. Mains voltage is low
3. The inverter power is
small
4: Output phase loss
1. Check load or reduce
load mutation
2. Check input power
3. Choose the inverter
with larger power
4. Check the output
wiring
7
E.oU1
Overvoltage when
accelerating
1. Input voltage is
abnormal
2. After momentary power
failure, restart the motor
that is rotating
3. Acceleration time is too
short
1. Check input power
2. Avoid re-starting at the
state of stop
3. Increase acceleration
time
