130
AC drive over-
temperature
(fault, heatsink)
Too high temperature measured in power
unit’s heatsink or board. Heatsink tem-
perature is over 100 °C (212 °F).
Check the correct amount and flow of
cooling air.
Check the heatsink for dust.
Check the ambient temperature.
Make sure that the switching fre-
quency is not too high in relation to
ambient temperature and motor load.

15 140 Motor stalled Motor is stalled. Check motor and load.
16 150
Motor overtem-
perature
Motor is overloaded.
Decrease motor load.
If no motor overload exists, check the
temperature model parameters.
17 160 Motor underload Motor is underloaded. Check load.
19
180
Power overload
(short-time super-
vision)
Drive power is too high. Decrease load.
181
Power overload
(long-time super-
vision)
25
Motor control
fault
Start angle identification has failed.
Generic motor control fault.
32 312 Fan cooling Fan life time is up.
Change fan and reset fan life time
counter.
33
Fire mode
enabled
Fire mode of the drive is enabled. The
drive's protections are not in use.
37 360
Device changed
(same type)
Option board changed for one previously
inserted in the same slot. The board’s
parameter settings are saved.
Device is ready for use. Old parame-
ter settings will be used.
38 370
Device changed
(same type)
Option board added. The option board
was previously inserted in the same slot.
The board’s parameter settings are
saved.
Device is ready for use. Old parame-
ter settings will be used.
39 380 Device removed Option board removed from slot. Device no longer available.
40 390 Device unknown
Unknown device connected (power unit/
option board).
Device no longer available.
41 400
IGBT tempera-
ture
IGBT temperature (unit temperature +
I
2
T) is too high.
Check loading.
Check motor size.
Make identification run.
43
420
Encoder fault
Encoder 1 channel A is missing.
Check encoder connections.
Check encoder and encoder cable.
Check encoder board.
Check encoder frequency in open
loop.
421 Encoder 1 channel B is missing.
422 Both encoder 1 channels are missing.
423 Encoder reversed.
424 Encoder board missing
