Possible cause
• component failure
• faulty operation
The DC-link voltage has gone
below the internal safety limit:
• most probable cause: supply
voltage is too low
• frequency converter internal
fault
• Power outages
Current measurement has
detected that there is no current
in one motor phase.
Heat sink temperature is under
°C
-10
Heat sink is overheated.
Motor stall protection has
tripped.
Motor overheating has been
detected by frequency converter
motor temperature model. Motor
is overloaded.
Motor underload protection has
tripped.

Correcting actions
Reset the fault and
restart.
If the fault re-occurs, con-
tact the distributor near to
you.
NOTE! If fault F8 occurs,
find out the subcode of the
fault from the Fault His-
tory menu under Id xxx!
In case of temporary sup-
ply voltage break reset the
fault and restart the fre-
quency converter. Check
the supply voltage. If it is
adequate, an internal fail-
ure has occurred.
Contact the distributor
near to you.
Check motor cable and
motor.
Check the ambient tem-
perature.
Check that the cooling air
flow is not blocked.
Check the ambient tem-
perature.
Make sure that the
switching frequency is not
too high in relation to
ambient temperature and
motor load.
Check that the motor is
able to rotate freely.
Decrease the motor load.
If no motor overload
exists, check the temper-
ature model parameters.
Check motor and load,
e.g. for broken belts or dry
pumps.
