User Manual of EM760 High-Performance 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 ofF07.18, F07.32 and F07.36. 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, protection retries will be carried out based on the last count. 6.10.5 Protective action setting With regard to some protections, the action mode ofthe 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. 197 Output terminal action options 1: action F07.16 Interval of protection retries 0.01~30.00 s 0.50 ● F07.17 Restoration time of protection retries 0.01~30.00 s 10.00 ● F07.18 Action option of protection E08 * E07 * E02 E06 E05 E04 00000000 O 0: allow protection retry 1: disable protection retry F07.32 Action option 2 of protection E10 E13 E15 E16 * E19 E20 * 111111 O 0: allow protection retry 1: disable protection retry F07.36 Action option 3 of protection * * * * * * E09 E17 11 O 0: allow protection retry 1:
