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.
Punch press (X, Y feed positioning
)
Y axis
servomotor
Gear and ball screw

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.
Palletizer
Servo
amplifier
Conveyor
Servomotor
(with a brake)
Reduction
gear
Ball screw
Palletizer
G
Conveyor control
Unloader control
Position detector
LD77MS
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.

LD77MS
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.
