Programming Example 2
Capture the position converted from the number of pulses that the servo motor feeds back to the servo
drive according to axis parameters when the external signal triggers DI7 of servo’s CN1 under Mode 2.


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.
