14
130
AC drive overtemper-
ature (fault, heatsink)
The temperature is too low
in the heatsink of the power
unit or in the power board.
The temperature limits of
the heatsink are different in
all the frames.
Do a check of the actual quantity
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.
131
AC drive overtemper-
ature (alarm, heat-
sink)
132
AC drive overtemper-
ature (fault, board)
133
AC drive overtemper-
ature (alarm, board)
136
Overvoltage protec-
tion circuit tempera-
ture (alarm)
Too high an output capaci-
tance or an earth fault in the
floating network.
Do a check of the cables and the
motor.
137
Overvoltage protec-
tion circuit tempera-
ture (fault)
Too high an output capaci-
tance or an earth fault in the
floating network.
Do a check of the cables and the
motor.
15
140
Motor stall
The motor stalled.
Do a check of the motor and the
load.
16
150
Motor overtempera-
ture
The load is too heavy on the
motor.
Decrease the motor load. If there is
no motor overload, do a check of
the motor thermal protection
parameters (parameter group 3.9
Protections).
17
160
Motor underload
The load is not sufficient on
the motor.
Do a check of the load.
Do a check of the parameters.
Do a check of the du/dt and sinus
filters.
19
180
Power overload
(short-time supervi-
sion)
The power of the drive is too
high.
Decrease the load.
Examine the dimensioning of the
drive. Examine if it is too small for
the load.
181
Power overload
(long-time supervi-
sion)

240
Motor control fault
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.
Reset the fault and restart the
drive.
Increase the identification current.
See the fault history source for
more information.
