When the "reference axis speed" is set during interpolation control, set so the major axis side becomes the reference axis. If
the minor axis side is set as the reference axis, the major axis side speed may exceed the "[Pr.8] Speed limit value".
(7) Interpolation speed designation method
To perform interpolation control, set the composite speed or reference axis speed in "[Pr.20] Interpolation speed
designation method" or "[Da.29] Interpolation speed designation method" of the reference axis.
• 0: Composite speed: The movement speed for the control target is designated, and the speed for each axis
is calculated by the LD75.
• 1: Reference axis speed: The axis speed set for the reference axis is designated, and the speed for the other
axis carrying out interpolation is calculated by the LD75.
When the composite speed is designated
X axis
Specify composite speed.
Calculated by the LD75.
• To designate interpolation speed for each positioning data, use "[Da.29] Interpolation speed designation
method".
• To set the same interpolation speed in all the positioning data, setting "[Pr.20] Interpolation speed
designation method" enables batch designation of the interpolation speed designation method for each
positioning data. To use "[Pr.20] Interpolation speed designation method", set 0 in "[Da.29] Interpolation
speed designation method". When a value other than 0 is set, "[Da.29] Interpolation speed designation
method" will be valid.
