Danfoss VLT AQUA Drive FC 202 Operating Instructions Manual page 40

Maintenance, Diagnostics an...
•
Blocked airflow around the frequency converter
•
Damaged heatsink fan
•
Dirty heatsink
This alarm is based on the temperature measured by the
heatsink sensor mounted inside the IGBT modules
Troubleshooting
•
Check fan resistance
•
Check soft charge fuses
•
IGBT thermal sensor
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and the
motor is missing.
Remove power from the frequency converter and check
motor phase U.
ALARM 31, Motor phase V missing
7 7
Motor phase V between the frequency converter and the
motor is missing.
Remove 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.
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. 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 7.6 is displayed.
Troubleshooting
•
Cycle power
•
Check that the option is properly installed
•
Check for loose or missing wiring
Contact the Danfoss supplier or service department if
required. Note the code number for further trouble-
shooting directions.
