The function of retry after failure is to prevent the impact of accidental faults on the
normal operation of the system. This is valid only for the faults listed in F07.18.
If retry after failure is enabled, this will be performed when a corresponding fault
occurs. That is, the fault will be reset. The fault status depends on F07.15 and the output of
the digital output terminal. If a fault is still detected after the retry interval, the retry will be
continued to the set number of retries after failure (F07.14) and then the corresponding fault
will be reported. If the fault is not detected after several retries, the retries will be deemed
successful and the inverter will continue to run normally.
When the retries after failure succeed and no fault is detected within the recovery time
(F07.17), the number of retries after failure will be cleared. If a fault occurs again, retries
will be performed from zero. In the case of a fault within this period, retries will be carried
out based on the last count.

With regard to some faults, the action mode of the inverter can be selected via this
function code. The inverter will stop running freely when the corresponding bit is set to 0
and according to the stop mode (F04.19) when the corresponding bit is set to 1.
These two function codes are subject to bit operation. You only need to set the
corresponding bit to 0 or 1. As shown in the table below:
