12 DATA USED FOR POSITIONING CONTROL
12.4 Positioning Data
■
Default value
The default value is 0 for all the axes.
[Da.7] Arc address
The arc address is the data required only when the circular interpolation control or 3-axis helical interpolation control is
performed.
• When the circular interpolation with sub point specified is performed, set the sub point (passing point) address as the arc
address.
• When the circular interpolation with center point specified is performed, set the center point address of the arc as the arc
address.
When the circular interpolation control or 3-axis helical interpolation control is not performed, the value set in [Da.7] Arc
address is invalid.
■
Buffer memory address
For the buffer memory address of this area, refer to the following.

■ Setting range
The setting range depends on the setting of [Pr.1] Unit setting and [Da.2] Control method.
• When [Pr.1] Unit setting is mm
*1 Note that the maximum available radius in the circular interpolation control is 536870912, although the value of the arc address can be
input within the range in the table above.
• When [Pr.1] Unit setting is degree
No control method requires the setting of the arc address with degree.
