switching the power light. When the fault has been removed, the motor can be restarted.
6.2.3 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
ASTOR 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 code
Fault type
Possible cause
Solutions
OUt1
IGBT Ph-U fault
The acceleration is too
fast
IGBT module fault
Misaction caused by
interference
The connection of the
driving wires is not
good,
Grounding is not
properly
Increase Acc time
Change the power unit
Check the driving wires
Inspect external
equipment and
eliminate interference
OUt2
IGBT Ph-V fault
OUt3
IGBT Ph-W fault
OC1
Over-current
when
acceleration
1. The acceleration or
deceleration is too fast.
2. The voltage of the grid
is too low.
3. The power of the
inverter is too low.
4. The load transients or
is abnormal.
5. The grounding is short
circuited or the output is
phase loss.
6. There is strong external
interference.
7. The overvoltage stall
protection is not open.
1. Increase the ACC time
2. Check the input power
3. Select the inverter with
a larger power
4. Check if the load is
short circuited (the
grounding short circuited
or the wire short
circuited) or the rotation
is not smooth.
5. Check the output
configuration.
6. Check if there is strong
interference.
7. Check the setting of
relative function codes.
OC2
Over-current
when
deceleration
OC3
Over-current
when constant
speed running
OV1
Over-voltage
when
acceleration
1. The input voltage is
abnormal.
2. There is large energy
feedback.
3. No braking
components.
4. Braking energy is not
open
1. Check the input power
2. Check if the DEC time
of the load is too short or
the inverter starts during
the rotation of the motor
or it needs to increase the
energy consumption
components.
3. Install the braking
components.
4. Check the setting of
relative function codes.
OV2
Over-voltage
when
deceleration
OV3
Over-voltage
when constant
speed running
