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 a serial bus or optional fieldbus
for diagnostics. See also parameter 16-94 Ext. Status Word.
WARNING 1, 10 Volts low
The control card voltage is less than 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Maximum 15 mA or minimum 590 Ω.
A short circuit in a connected potentiometer or incorrect
wiring of the potentiometer can cause this condition.
