Chapter 5 Data Used for Positioning Control
When "[Pr.1] Unit setting" is "inch"
The table below lists the control systems that require the setting of the positioning
address or movement amount and the associated setting ranges.
(With any control system excluded from the table below, neither the positioning
address nor the movement amount needs to be set.)

1: Set an integer because the sequence program cannot handle fractions.
(The value will be converted properly within the system.)
[Da.7] Arc address
The arc address is data required only when carrying out circular interpolation
control.
(1) When carrying out circular interpolation with sub point designation, set the sub
point (passing point) address as the arc address.
(2) When carrying out circular interpolation with center point designation, set the
center point address of the arc as the arc address.
End point address
(Address set with Da.6 )
Sub point
(Address set with Da.7 )
Start point address (Address before starting positioning)
Start point address (Address before starting positioning)
Center point address
(Address set with Da.7 )
End point address
(Address set with Da.6 )
<(1) Circular interpolation with sub
point designation>
<(2) Circular interpolation with center
point designation>
When not carrying out circular interpolation control, the value set in "[Da.7] Arc
address" will be invalid.
