7.2 Failure record lookup
This series inverter can record latest 6 failure code and inverter run parameter of
the last failure, to search these informations can redound to finding out reason of the
failure.
Failure information is all stored in Fd group parameter，please enter into Fd group
parameter to see about information by referring to keypad operation method.

7.3 Failure reset
To resume normal running when failure takes place in the inverter, you can
choose following any kind of operation:
(1) After you set any terminal of X1~X8 to be inputted by external RESET
(F5.00~F5.07=11), you can open it after connected to COM.
(2) When failure code is displayed，press key after restoration is
confirmed.
(3) Cut off power supply.
STOP
RESET
(1) Before reset you must find out reason of failure downright and eliminate it，
otherwise may cause permanent damage to the inverter.
(2) If can’t reset or failure takes place again after resetting, should look for reason and
continuous resetting will damage the inverter.
(3) Reset should take place 5 minutes after overload, overheat protection action.

E013 inverter module fault. system will lock the output when this fault appear , and
cannot directly reset, must cut off the power and inspect, restart with power after
confirming no abnormal , the fault can be remove .
