8.1
What this chapter contains
This chapter tells how to reset faults and view fault history. It also lists all alarm and fault messages
including the possible cause and corrective actions.

Only qualified electricians are allowed to maintain the inverter. Read the safety
instructions in chapter
Safety precautions
before working on the inverter.
8.2
Alarm and fault indications
Fault is indicated by LEDs. See
Keypad operation Procedure
. When TRIP light is on, an alarm or
fault message on the panel display indicates abnormal inverter state. Using the information given in
this chapter, most alarm and fault cause can be identified and corrected. If not, contact with the INVT
office.
8.3
How to reset
The inverter can be reset by pressing the keypad key STOP/RST, through digital input, or by
switching the power light. When the fault has been removed, the motor can be restarted.
8.4 Fault history
Function codes P07.28
–
P07.37 store 10 recent faults. Function codes P07.38
–
P07.45 ,
P07.46
–
P07.54 , and P07.55
–
P07.61 show inverter operation data at the time the latest 3 faults
occurred.
8.5 Inverter faults and solutions
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.
