Default value: No tolerance check.
R13=1. Tool out of tolerance flag.
Using this flag prevents a tool OUT OF TOLERANCE
alarm from being raised.
R14=t t= Tool offset edge to be updated (usually up to nine
edges).
R14=3 Updates the current tool offset, edge D3.
If R14 is not input, the current tool offset edge (D) is
updated. The current tool is the number of the tool in
the spindle.
R17=q q= Overtravel distance.
For details, see "Setting-data subroutine L9760" on
page 13.
Default value: 5.0 mm (0.197 in)
R19=s s= Spindle speed at which length measurement takes
place. For details, see "Setting-data subroutine L9760"
on page 13.
Default value: 3150 rev/min
R25=y y= Radial step-over for length setting.
This is the offset across the beam at which length
measurement takes place. The value must be less than

on the beam centre-line.
