Fixed-Pitch Feed Control Using 3 Axes Linear
Interpolation
Fixed-pitch feed control using 3 axes linear interpolation from the current stop position with the specified 3 axes.
Fixed-pitch feed control using 3 axes linear interpolation uses the FEED-3 servo instruction.

Processing details
• Positioning control from the current stop position "0" to the position which combined travel direction and travel value
specified with each axis is executed.
• The travel direction for each axis is set by the sign (+/ -) of the travel value for each axis, as follows:
Travel direction
Positive travel value
Negative travel value
Positioning direction
Forward direction
Forward
direction
Z-axis travel
value
Reverse

Do not set the travel value to "0" for fixed-pitch feed control.
The following results if the travel value is set to "0":
• If the travel value of all axes are set to "0", fixed-pitch feed completion without fixed-pitch feed.
