E-Stop Active (unwinds)
For safety reasons E-Stop occurs with an open
circuit. The logic is therefore different than the
other digital inputs. E-Stop can also be mistakenly
activated by selecting Digital Input Mode Active
High when it is wired active low (and the other way
around). See Section 5.2 and Figure 4.
