5-2. Check the fault records
The inverter records the last 6 times fault code and the running parameter of last fault. Checking these information can help
to solve the problem. The fault records are stored in P6.
5-3. Fault reset
Once the fault occurs, select one of the following operations to restart the inverter:
(1) When fault code displayed in the operation panel, press key after you confirm the inverter can be reset.
(2) After setting one terminal among X1~X8 as external RESET input (P4.00~P4.07=17), connect it with COM terminal
and then disconnect.
(3) Cut off the power supply
(1) Please make sure you know the reason of the fault and get rid of it before resetting, otherwise the inverter may be
damaged permanently.
(2) If the inverter can not be reset or fault reoccurred after resetting, please check the reason as the inverter may be dam-
aged by resetting continuously.
(3) Delay 5 minutes to reset when overload and overheat protection are enabled.
