text: <s>[INST] powerflex 40 what is the difference between these settings on the dip switch??? Sink/SourceDIP Switch [/INST] You may choose if PF40 Inputs can be wired as Sink (SNK) or Source (SRC) via that DIP Switch setting. Leaving it as default (SRC) means you will use the positive wire to connect your inputs, to have them Active HIGH; on the contrary, setting it at SNK will allow you to connect your digital inputs to the negative wire (common) having them Active LOW - fuzzy logic \\n </s>
