If
digital output terminal (03-10~03-13(P.40,P.85，P.129~P.130),03-42~03-57(P.568~P.583)) is set to 18, it is the
maintenance alarm function. If the operating days of inverter reach set value of maintenance alarm time parameter
06-17(P.261), multi-function digital output terminal or multi-function relay of inverter will output a signal.

Short circuit to ground
Short circuit to ground detection after power-on is set by 06-19(P.282).
06-18(P.280) is used to set whether check when start, 06-19(P.282) is also used to set during operation.
If 06-18(P.280) is set 1 and output short-circuited current exceeds 50% of rated current when start, inverter will
stop outputting and trigger GF alarm.
During operation, output short-circuited current exceeds
set value of 06-19(P.282) % rated current, inverter will
stop outputting and trigger GF alarm.
