
As Vel_Ex changes to TRUE, Vel_Bsy changes to TRUE. One period later, Vel_Act changes to
TRUE and the servo motor starts to move forward. Vel_Invel changes to TRUE when the servo
motor reaches the target velocity.

As Stp_Ex changes to TRUE, Stp_Bsy changes to TRUE. One period later, Stp_Act changes
to TRUE, meanwhile Vel_Invel changes to FALSE, Vel_Abt changes to TRUE and the servo
motor starts to decelerate.

When the axis velocity is decreased to 0, Stp_Done changes to TRUE and meanwhile Stp_Bsy,
Stp_Act remain TRUE.

As Stp_Ex changes to FALSE, Stp_Done, Stp_Bsy and Stp_Act change to FALSE
simultaneously.
