Sequence of case ①:
1.
The machine part mo
ves in posive direcon with prole data set 1.
2.
Machine part r
everses to posive travel range switch (B) and changes to prole data set 2.
3.
The negave edge of the travel range limit switch (B) acvates the touch probe detecon.
4.
The f
ollowing posive edge of the encoder zero pulse/touch probe sensor (A) sets the ref-
er
ence.
