For D, E, and F enclosures, this alarm is based on the
temperature measured by the heat sink sensor mounted
inside the IGBT modules. For the F enclosures, the thermal
sensor in the rectifier module can also cause this alarm.
Troubleshooting
•
Check the fan resistance.
•
Check the soft charge fuses.
•
Check the IGBT thermal sensor.
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and the
motor is missing.
Troubleshooting
•
Remove the power from the frequency converter
and check motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the frequency converter and the
motor is missing.
Troubleshooting
•
Remove the power from the frequency converter
and check motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the frequency converter and the
motor is missing.
Troubleshooting
•
Remove the power from the frequency converter
and check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period.
Troubleshooting
•
Let the unit cool to operating temperature.
WARNING/ALARM 34, Fieldbus communication fault
The fieldbus on the communication option card is not
working.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and 14-10 Mains Failure is
not set to option [0] No Function. Check the fuses to the
frequency converter and mains supply to the unit.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
Table 9.2 is displayed.
Troubleshooting
•
Cycle the power.
•
Check that the option is properly installed.
•
Check for loose or missing wiring.
It may be necessary to contact Danfoss Service or the
supplier. Note the code number for further trouble-
shooting directions.
