(9) [Pr.19] Speed switching mode
Set whether to switch the speed switching mode with the standard switching or front-loading switching mode.
0: Standard switching Switch the speed when executing the next positioning data.
1: Front-loading switching The speed switches at the end of the positioning data currently being executed.
For standard switching

(10)[Pr.20] Interpolation speed designation method
When carrying out linear interpolation/circular interpolation, set whether to designate the composite speed or
reference axis speed.
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 Composite speed is set

Designate composite speed
Calculated by LD75
Note) Always specify the reference axis speed if the 4-axis linear interpolation or 2 to 4 axis speed control has to
be performed. If the composite speed is specified instead, the error "Interpolation mode error" (error code:
523) will be output when the positioning operation is attempted. For a positioning operation that involves
the circular interpolation or 3-axis helical interpolation control, specify the composite speed. The
interpolation speed designation method can be set for each positioning data with the positioning option
("[Da.29] Interpolation speed designation method") of the positioning data.
