7.3 Fault reset
The fault causes must be identified and removed completely
prior to reset, otherwise it may cause permanent damage to
the inverter.
If the inverter can’t be reset or fault occurs after reset, it’s
necessary to find out causes, otherwise continuous reset will
damage the inverter.
The protection actions of overload and overheat should be
delayed for 5 minutes when reset.
To recover to the normal operation when the inverter fault occurs, it’s optional to
choose any of the following operations.
Method I: Press
RUN
STOP
key when displaying fault
code.
Method II: Disconnect after closure of external multi-function terminals X1~X4
(fault reset) and CM.
Method III: Send the fault reset command via RS485 interface.
Method IV: Cut off power supply.
