Danfoss AKD 5001 Manual page 109

If the enclosure is IP 00 or IP 20/NEMA 1, the cut-out
temperature of the heat-sink is 90°C. If IP 54 is
used, the cut-out temperature is 80°C.
The tolerance is ± 5°C. The temperature fault
cannot be reset, until the temperature of the
heat-sink is below 60°C.
The fault could be the following:
- Ambient temperature too high
- Too long motor cable
- Too high switching frequency.
ALARM: 30
Motor phase U missing
(MISSING MOT.PHASE U):
Motor phase U between frequency converter
and motor is missing.
Turn off the frequency converter and check
motor phase U.
ALARM: 31
Motor phase V missing
(MISSING MOT.PHASE V):
Motor phase V between frequency converter
and motor is missing.
Turn off the frequency converter and check
motor phase V.
ALARM: 32
Motor phase W missing
(MISSING MOT.PHASE W):
Motor phase W between frequency converter
and motor is missing.
Turn off the frequency converter and check
motor phase W.
ALARM: 33
Quick discharge not OK
(QUICK DISCHARGE NOT OK):
Check whether a 24 Volt external DC supply has
been connected and that an external brake/discharge
resistor has been fitted.
WARNING/ALARM: 34
Fieldbus communication fault
(FIELDBUS COMMUNICATION FAULT):
The fieldbus on the communication option
card is not working.
WARNING: 35
Out of frequency range
(OUT OF FREQUENCY RANGE):
This warning is active if the output frequency has
reached its Output frequency low limit (parameter 201)
or Output frequency high limit (parameter 202). If
the frequency converter is in Process control, closed
loop (parameter 100), the warning will be active in the
display. If the frequency converter is in another mode
108
AKD 5000
than Process control, closed loop, bit 008000 Out of
frequency range in extended status word will be active,
while there will be no warning in the display.
