The alarm words, warning words and extended status words can be read out via 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 below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
A short circuit in a connected potentiometer or improper
wiring of the potentiometer can cause this condition.
