Possible cause
Too high a temperature in
the heatsink of the power
unit or in the power board.
The temperature limits of
the heatsink are different in
all the frames.
Too high an output capaci-
tance or an earth fault in the
floating network.
Too high an output capaci-
tance or an earth fault in the
floating network.
The motor stalled.
There is too heavy a load on
the motor.
There is not a sufficient load
on the motor.
The power of the drive is too
high.
This fault is available only if
you use a customer-specific
application. A malfunction in
the start angle identifica-
tion.
The rotor moves during
•
identification.
The new angle does not
•
agree with the old
value.

How to correct the fault
Do a check of the actual amount
and flow of cooling air.
Examine the heatsink for dust.
Do a check of the ambient temper-
ature.
Make sure that the switching fre-
quency is not too high in relation to
the ambient temperature and the
motor load.
Do a check of the cooling fan.
Do a check of the cables and the
motor.
Do a check of the cables and the
motor.
Do a check of the motor and the
load.
Decrease the motor load. If there is
no motor overload, do a check of
the motor thermal protection
parameters (parameter group 3.9
Protections).
Do a check of the load.
Do a check of the parameters.
Do a check of the du/dt and sinus
filters.
Decrease the load.
Examine the dimensions of drive.
Examine if it is too small for the
load.
Reset the fault and restart the
drive.
Increase the identification current.
See the fault history source for
more information.
