Table 5.4 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 16-94 Ext. Status Word.
WARNING 1, 10 Volts low:
The 10V voltage from terminal 50 on the control card is
below 10V.
Remove some of the load from terminal 50, as the 10V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
WARNING 5, DC link voltage high:
The DC bus voltage is higher than the overvoltage limit of
the control system. The AFE is still active.
WARNING 6, DC link voltage low
The DC bus voltage is below the undervoltage limit of the
control system. The AFE is still active.
