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.
