[Program Example]

POINT
(1) Do not set the travel value to zero for fixed-pitch feed control.
The following results if the travel value is set to zero:
(a) If both axes are set to zero, the fixed-pitch feed ends with no feed
taking place.
(b) If the travel value is set to zero for 1-axis only, fixed-pitch feed control
will not occur at the normal positioning speed for the axis set to a
non-zero travel value.
This program conducts fixed-pitch feed control using 2-axes linear interpolation
under the conditions below.
(1) System configuration
Fixed-pitch feed control using 2-axes linear interpolation of Axis 2 and Axis 3.
(2) Positioning conditions
The fixed-pitch feed control conditions are shown below.
