7.3 Fault reset
¾ The fault causes must be identified and removed completely prior
to reset, otherwise it may cause permanent damage to the inverter.
¾ If the inverter can’t be reset or fault occurs after reset, it’s necess-
ary to find out causes, otherwise continuous reset will damage the
inverter.
¾ 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.
