User Manual of EM730/EM730E Series Inverter The function of protection retry is to prevent the impact of occasional protection on the normal operation of the system. This is valid only for protections of F07.18, F07.32 and F07.34. If protection retry is enabled, this will be performed after a corresponding protection. That is, the protection will be reset. The protection status depends on F07.15 and the output of the digital output terminal. If a fault is still detected after the protection retry interval, the protection retry will be continued to the set number of protection retries (F07.14) and then the corresponding protection will be reported.
If the fault is not detected after several protection retries, the protection retries will be deemed successful and the inverter will continue to run normally. When protection retries succeed and no trip protection is enabled within the recovery time (F07.17), the number of protection retries will be cleared. When a protection is enabled again, protection retries will be performed from zero. In case of any trip protection within this period, 205 Function Function code Default Parameter description Unit Attribute code name setting F07.14 Protection retries 0-20; 0: Disable protection retry 0 〇 F07.15 Options of digital output action in protection retries 0: no action 1:
