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 the serial bus or optional serial communication bus for diagnosis. See
also par. 16-90 - 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 over-
loaded. 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 adjustable frequency
drive.
WARNING/ALARM 4, Line phase loss:
A phase is missing on the supply side, or the AC line voltage imbalance
is too high.
This message also appears in case of a fault in the input rectifier on the
adjustable frequency drive.
Check the supply voltage and supply currents to the adjustable frequency
drive.

WARNING 5, DC link voltage high:
The intermediate circuit voltage (DC) is higher than the overvoltage limit
of the control system. The adjustable frequency drive is still active.
WARNING 6, DC link voltage low
The intermediate circuit voltage (DC) is below the undervoltage limit of
the control system. The adjustable frequency drive is still active.
WARNING/ALARM 7, DC overvoltage:
If the intermediate circuit voltage exceeds the limit, the ad-
justable frequency drive trips after a given period of time.
Possible corrections:
Connect a brake resistor
Extend the ramp time
Activate functions in par. 2-10
Increase par. 14-26
