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 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.
Remove power from the frequency converter and check
motor phase V.
7 7
ALARM 32, Motor phase W missing
Motor phase W between the frequency converter and the
motor is missing.
Remove 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. 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 [0] No Function.
Troubleshooting
•
Check the fuses to the frequency converter and
mains power supply to the unit.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
the Table 7.4 is displayed.
Troubleshooting
•
Cycle power.
•
Check that the option is properly installed.
•
Check for loose or missing wiring.
Contact the Danfoss supplier or Danfoss service if required.
Note the code number for further troubleshooting
directions.
