  When Vel_Ex changes to TRUE, Vel_Bsy changes to TRUE and one period later, Vel_Act 
changes to TRUE and the servo motor starts to move forward. Vel_Invel changes to TRUE as 
the servo motor reaches the target velocity. 
  When Hlt_Ex changes to TRUE, Hlt_Bsy changes to TRUE and one period later, Hlt_Act 
changes to TRUE. Meanwhile, Vel_Invel changes to FALSE and Vel_Abt changes to TRUE 
and then the servo motor starts to decelerate. 
  When the axis velocity is decreased to 0, Hlt_Done changes to TRUE and meanwhile, Hlt_Bsy 
and Hlt_Act change to FALSE. 
  As Hlt_Ex changes to FALSE, Hlt_Done changes to FALSE.
