Table 6.3: Description of Alarm Word, Warning Word and Extended Status Word
The alarm words, warning words and extended status words can be read out via serial bus or optional network for diagnose. See alsopar. DR-94 Ext. Status
Word.
WARNING 1, 10 Volts low:
The 10 V voltage from terminal 50 on the control card is below 10 V.
Remove some of the load from terminal 50, as the 10 V supply is overloaded.
Max. 15 mA or minimum 590 Ω.
WARNING/ALARM 2, Live zero error:
The signal on terminal 53 or 54 is less than 50% of the value set in par.
AN-10 Terminal 53 Low Voltage, par. AN-12 Terminal 53 Low Current, par.
AN-20 Terminal 54 Low Voltage, or par. AN-22 Terminal 54 Low Current re-
spectively.
WARNING/ALARM 3, No motor:
No motor has been connected to the output of the frequency converter.
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 in case of a fault in the input rectifier on the fre-
quency converter.
Check the supply voltage and supply currents to the frequency converter.
WARNING 5, DC link voltage high:
The intermediate circuit voltage (DC) is higher than the over-voltage limit of
the control system. The frequency converter is still active.
WARNING 6, DC link voltage low
The intermediate circuit voltage (DC) is below the under-voltage limit of the
control system. The frequency converter is still active.
WARNING/ALARM 7, DC over voltage:
If the intermediate circuit voltage exceeds the limit, the frequency con-
verter trips after a time.
Possible corrections:
Connect a brake resistor
Extend the ramp time
Activate functions in par. B-10 Brake Function
Increase par. SP-26 Trip Delay at Drive Fault
