Operation Example
In this sample, BufferMode
(Buffer Mode Selection) is set to Buffered for MC_MoveAbsolute (Abso-
lute Positioning) instructions and the axis is moved to the final target position by executing multiple in-
structions.
When the axis reaches the final target position, it is returned to home with the MC_ZeroPosition (High-
speed Home) instruction.
Multi-execution of instructions is performed when the Active (Controlling) output variable from the pre-
vious instruction is TRUE. For single-axis operation, multi-execution is possible for only one instruc-
tion.

1 Turning ON the Operation Start Switch
When you turn ON the operation start switch at home, axis 1 is positioned to 50.00 mm in the pos-
itive direction.
2 Turning ON the Operation Start Switch Again
Thereafter, axis 1 is positioned to 100.00 mm and 200.00 mm, and then returns to home and
stops. The operation start switch must be turned ON once for each of these motions.
