1.1.2 Purpose and applications of positioning control
"Positioning" refers to moving a moving body, such as a workpiece or tool (hereinafter,
generically called "workpiece") at a designated speed, and accurately stopping it at the
target position. The main application examples are shown below.

•
To punch insulation material or leather, etc.,
as the same shape at a high yield, positioning
is carried out with the X axis and Y axis
servos.
•
After positioning the table with the X axis
servo, the press head is positioned with the Y
axis servo, and is then punched with the
press.
•
When the material type or shape changes, the
press head die is changed, and the positioning
pattern is changed.

•
Using the servo for one axis, the palletizer is
positioned at a high accuracy.
•
The amount to lower the palletizer according to
the material thickness is saved.

•
The ATC tool magazine for a compact
machining center is positioned.
•
The relation of the magazine's current value
and target value is calculated, and positioning
is carried out with forward run or reverse run to
achieve the shortest access time.
