[Da.7] Arc address
The arc address is data required only when carrying out 2-axis circular interpolation control or 3-axis helical interpolation
control.
• When carrying out circular interpolation with sub point designation, set the sub point (passing point) address as the arc
address.
• When carrying out circular interpolation with center point designation, set the center point address of the arc as the arc
address.
Sub point
(Address set with [Da.7])
Start point address (Address before starting positioning)
<(1) Circular interpolation with sub point designation>
When not carrying out 2-axis circular interpolation control or 3-axis helical interpolation control, the value set in "[Da.7] Arc
address" will be invalid.
■When "[Pr.1] Unit setting" is "mm"
The table below lists the control methods that require the setting of the arc address and shows the setting range.
(With any control method excluded from the table below, the arc address does not need to be set.)
[Da.2] setting value
ABS circular sub: 0DH
ABS circular right: 0FH
ABS circular left: 10H
INC circular sub: 0EH
INC circular right: 11H
INC circular left: 12H
ABS helical sub: 20H
ABS helical right: 22H
ABS helical left: 23H
INC helical sub: 21H
INC helical right: 24H
INC helical left: 25H
*1 Set an integer because the program cannot handle fractions.
(The value will be converted properly within the system.)
*2 Note that the maximum radius that 2-axis circular interpolation control is possible is 536870912 (  10
can be input within the range shown in the above table, as an arc address.
■When "[Pr.1] Unit setting" is "degree"
No control method requires the setting of the arc address by "degree".
