When "free stop" is selected, the inverter displays Err. *, and directly stops.When "Stop at the
selected mode" is selected, the inverter displays Arr. *, firstly stops at the selected mode and then
displays Err. * When "continue to run" is selected, the inverter continues to run and displays Arr. *,
the operating frequency is set by F8.24.

When the inverter occurs faults during operation, and the troubleshooting mode for the fault
is set to "continue to run", the inverter displays Arr. *, and runs at the operating frequency set by
F8.24.
When "abnormal spare frequency" is selected, the value set by F8.25 is the percentage of the
maximum frequency.
