Changing the function of a digital output
To change the function of a digital output, you
must interconnect the digital output with a binector
output of your choice.

Changing the function of a digital output - Example
To output inverter fault messages via digital output DO
1,
you must interconnect DO1 with the fault messages: Set
p0731
= 52.3.
Advanced settings
You can invert the signal of the digital output using parameter p0748.
For more information, please see the parameter list and the function block diagrams 2230 f
of the List Manual.
