E008 Memory error
If the built-in memory has problems, the inverter turns
OFF its output. CPU error may be issued instead.
The inverter recovers by re-turning ON the power;
however, you need to check that there is no problem
in parameters. The data which has been backed up
on the operator keypad beforehand may be restored.
