Interpolation speed specification method
For the interpolation control, set the composite speed or reference axis speed with "[Pr.20] Interpolation speed specification
method" or "[Da.29] Interpolation speed specification method" of the reference axis.
Composite speed
The movement speed for the control target is specified, and the speed for
each axis is calculated by the positioning module.

If specifying the interpolation speed for each positioning data
To specify the interpolation speed for each positioning data, use "[Da.29] Interpolation speed specification method".
If setting the same interpolation speed using all positioning data
• The interpolation speed specification method for all positioning data can be specified en block by setting "[Pr.20]
Interpolation speed specification method".
• When "[Pr.20] Interpolation speed specification method" is used, set 0 in "[Da.29] Interpolation speed specification
method". When a value other than 0 is set, "[Da.29] Interpolation speed specification method" is enabled.

Function
When performing linear interpolation/circular interpolation, set
whether to specify the composite speed or the speed for the
reference axis.
• 0: Composite speed
• 1: Reference axis speed
Set "[Pr.20] Interpolation speed specification method" for each
positioning data.
0: Use the set value of [Pr.20] Interpolation speed specification
method
1: Composite speed
2: Reference axis speed
Reference axis speed
The axis speed set in the reference axis is specified, and the speed for the
other axis performing interpolation is calculated by the positioning module.
