5.4.1.3 General
faults
Faults,
displaying
"!! Fault!!
" in the first line, can be acknowledged by means of an inverter
reset
(
and
-
RESET
)
, provided the cause of the fault is no longer existing.
These are faults, causes of which are not necessarily due to a defective inverter.
They could as well be caused by wrong settings (parameterising) or by external influences.
In case of the faults mentioned below the
inverter is switched of electronically,
the failiure
must
be
acknowledged
always
with “
inverter reset
” :
