When Touch1_Ex changes from FALSE to TRUE, Touch1_Bsy changes from FALSE to TRUE
in the first cycle and Touch1_Act changes from FALSE to TRUE in the second cycle.

When the execution of DMC_TouchProbe is finished after the external signal triggers DI7 of
servo's CN1, Touch1_Done changes from FALSE to TRUE and Touch1_Pos outputs the
position converted from the number of pulses which the servo motor feeds back to the servo
drive according to the axis parameters. Meantime Touch1_Bsy and Touch1_Act change from
TRUE to FALSE. When Touch1_Ex changes from TRUE to FALSE, Touch1_Done changes
from TRUE to FALSE and the position that Touch1_Pos captures will not be cleared to 0.
