Fault diagnosis and countermeasures
Do as the following after the inverter fault:
1.
Check to ensure there is nothing wrong with the keypad. If not, please contact with SALICRU.
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 type
Possible cause
Solutions
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
rotation 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 opened.
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. Dynamic braking energy
unit is not activated
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 add the
dynamic braking components.
3. Install the braking
components.
4. Check the setting of relative
function codes.

deceleration
OV3
