Error during parameter
import or export
No/bad SD card
or the
parameter file
on the SD card is
incomplete or
does not exist
Use a complete parameter
file (parameter import) and
a complete SD card

Generator running
The motor runs
on the inverter
and stops
Wait until the motor is
stationary

Comparator's own error
test
Internal fault
If the fault still exists after
the power is turned off and
on, send the inverter for
repair.
