Table 6.2 Warnings and Alarms Code List
1) These faults can be caused by mains distortions. Installing Danfoss line filter could fix this problem.
The alarm words, warning words and extended status
words can be accessed via fieldbus or optional fieldbus for
diagnosis.
WARNING/ALARM 2, Live zero error
This warning or alarm only appears if programmed in
parameter 6-01 Live Zero Timeout Function
. The signal on 1
of the analog inputs is less than 50% of the minimum
value programmed for that input. Broken wiring or faulty
device sending the signal can cause this condition.
Troubleshooting
•
Check connections on all the analog input
terminals. Control card terminals 53 and 54 for
signals, terminal 55 common.
•
Check that the frequency converter programming
and switch settings match the analog signal type.
•
Perform the input terminal signal test.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the mains
voltage imbalance is too high. This message also appears
for a fault in the input rectifier on the frequency converter.
Options are programmed in
parameter 14-12 Function at
Mains Imbalance
.
Troubleshooting
•
Check the supply voltage and supply currents to
the frequency converter.
WARNING/ALARM 7, DC overvoltage
If the DC-link voltage exceeds the limit, the frequency
converter trips after a time.
Troubleshooting
•
Extend the ramp time.
•
Change the ramp type.
