Chapter 11 Motion Control Instructions 
11-51 
  When Addt_Ex changes from FALSE to TRUE, the motion controller controls the motion 
of the servo motor by taking current position as the reference point. Meanwhile, 
Addt_Bsy changes to TRUE and one period later, Addt_Act changes to TRUE. After the 
set distance is reached by the servo motor, Addt_Done changes from FALSE to TRUE 
and meanwhile Addt_Bsy and Addt_Act change from TRUE to FALSE. 
  When Addt_Ex changes from TURE to FALSE, Addt_Done is reset. 
  When Addt_Ex changes from FALSE to TRUE again after the servo motor reaches the 
set distance, the motion controller controls the motion of the servo motor and 
Addt_Done changes from FALSE to TRUE once again after the servo motor reaches 
the set distance.
