[Use example]
Use an OFST command to perform pitch feed.
Use a variable as a counter to count the number of feeds.
Use the X-axis and feeds the axis in positive direction.
Points
The OFST command is reflected only in movement commands.
Executing the OFST command alone does not move the axis.
Reference point
Pitch (mm)
(Number of feeds n)
Assign number of feeds (n = 4).
Assign pitch (80 mm).
Clear variable (counter).
Clear variable (offset).
Home return

Wait for start input.
Move.
Add pitch to offset.
Apply offset to X-axis.
Increment counter variable by 1.
Confirm end of feed.
Repeat, if specified number of
feeds not yet reached.
End program.
