User Manual of A90 Series Inverter 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. 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 If retry after failure is enabled, this will be performed when a corresponding fault 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. (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 When the retries after failure succeed and no fault is detected within the recovery time 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.
