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, 16-92 and 16-94.
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. 6-10, 6-12,
6-20, or 6-22 respectively.
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 frequency 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 overvoltage limit of the control system.
The frequency converter is still active.
