3.7 Fault instruction and solution
Do as the following after the inverter fault:
1. Check to ensure there is nothing wrong with the keypad. If not, please contact with the
local INVT office.
2. If there is nothing wrong, please check P07 and ensure the corresponding recorded fault
parameters to confirm the real state when the current fault occurs by all parameters.
3. See the following table for detailed solution and check the corresponding abnormal state.
4. Eliminate the fault and ask for relative help.
5. Check to eliminate the fault and carry out fault reset to run the inverter.

Fault
Cause
Solution
OUt1
IGBT U phase
protection
The acceleration is too fast
There is damage to the
internal to IGBT of the phase
The connection of the driving
wires is not good
The grounding is not good
 Increase ACC time
 Change the power unit
 Check the driving wires
 Check if there is strong
interference to the external
equipment
OUt2
IGBT V phase
protection
OUt3
IGBT W
phase
protection
OC1
Accelerating
overcurrent
The acceleration or
deceleration is too fast
The voltage of the grid is too
low
The power of the inverter is
too low
The load transients or is
Increase the ACC time
Check the input power
Select the inverter with a larger
power
Check if the load is short
circuited (the grounding short
circuited or the wire short
