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 fieldbus for diagnose. See also par. 16-90 - 16-94.
WARNING 1, 10 Volts low:
The 10 V voltage from terminal 50 on the con-
trol 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. 6-10, 6-12, 6-20,
or 6-22 respectively.

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 frequency convert-
er.
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 sys-
tem. The frequency converter is still active.
