Warnings and Alarms
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 the Danfoss supplier or
service department. Note the code number for further
troubleshooting directions.
