Insert the second MC_MoveRelative (Relative Positioning) instruction.
Enter Move2 as the instance name, enter the axis variable of axis 0 (MC_Axis000) for the in-out
variable, and enter the values in the following table for the input variables.
Input variable
Distance
Velocity
Acceleration
Deceleration
Additional Information
Cascade connections are possible for Ladder Diagram Instructions (e.g., LD (Load) and AND
(AND)), for FB instructions (e.g., MC_MoveRelative (Relative Positioning)), and for FUN instruc-
tions (e.g., MOVE (Move)). In this program, the Move2 instance is started after relative position-
ing for the Move1 instance is completed.

Enter an output for the Complete1 variable to turn ON when the round-trip operation is com-
pleted.
This concludes the creation of the instructions to repeatedly execute single-axis positioning.
