Danfoss VLT AutomationDrive FC 300 Operating Instructions Manual page 67

Warnings and Alarms
Blocked airflow around the frequency converter.
Damaged heatsink fan.
Dirty heatsink.
For the D, E, and F Frame sizes, this alarm is based on the
temperature measured by the heatsink sensor mounted
inside the IGBT modules. For the F Frame sizes, this alarm
can also be caused by the thermal sensor in the Rectifier
module.
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
Motor phase V between the frequency converter and the
motor is missing.
8 8
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 below is displayed.
Troubleshooting
Cycle power
Check that the option is properly installed
Check for loose or missing wiring
It may be necessary to contact your Danfoss supplier or
service department. Note the code number for further
troubleshooting directions.
