Fault indication with the discrete output
To indicate faults via the discrete output, set parameters as follows:
•
Discrete Output Source
= Fault
•
Discrete Output Fault Action
= None
Note
If Discrete Output Source is set to Fault and a fault occurs, the discrete output is always ON. The setting
of Discrete Output Fault Action is ignored.
