F41 IGBT tem perature fault
F41 displayed.
Check logged
data in
fault history.
Drive is too sm all if
software update and
param eter changes did
not help.
Check status of, at
reference.
Is it "0" or "1"?
Update system software, if
possible or provide colder
cooling air. Drive is too
sm all.
Measure actual output
current and com pare
it to m onitored value..
NO TE:
Calculated tem perature integral based on m easured current, is added to m easured tem perature
to describe tem perature rise of the IGBT´s.
W hen unit trips and goes into standby m ode, the values is stored.
Param eters to check are acceleration tim e, U/f curve, current lim it,
DC braking or switching frequency.
Software
has detected too
high short term
overload.
NO
YES
W as m easured
values = monitored
value?
YES
Actual overload
caused the trip.
Decrease load or
m ake changes to
param eter settings.
Drive can not reach
reference. Change
param eter setting, if
possible.
Internal fault in current
m easurem ent circuit.
Status
= "1"
Status
= "0"
F41 again?
W rong param eter
setting.
NO
Measure

Internal fault in

Circuit
is O K?
YES
NO
Overload or
internal fault
caused the trip.
