4-7. Description of micro arc function
DC has a micro arc function to quickly detect ARC when it occurs, and interrupt the output and
separate the load.
With the micro arc function, the interruption time and the detection level can be changed on the front
panel or via the SERIAL communication. Optimal arc handling can be performed by changing the
settings depending on the working load.
The use of signals from USER IO PORT enables the loading of micro arc signals.
For instructions on how to set the parameters, see "MARC" in Section 5-1-4.
