
When Touch_Ex changes from FALSE to TRUE, Touch_Bsy changes from FALSE to TRUE in
the first cycle and Touch_Act changes from FALSE to TRUE in the second cycle.

When the external signal triggers controller’s I0, DMC_TouchProbe starts to execute. When
Touch_Done changes from FALSE to TRUE, the position Touch_Pos outputs is converted from
the number of pulses that the externam encoder port of the controller receives through axis
parameters. Meantime Touch_Bsy and Touch_Act change from TRUE to FALSE. When
Touch_Ex changes from TRUE to FALSE, Touch_Done changes from TRUE to FALSE and the
position that Touch_Pos captures will not be cleared to 0

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.
