4. DESCRIPTION OF PARAMETERS
87
[Valid data range] 0 to 3999
Set distance Ls up to the end point in an inner corner for corner override.
If qx qp, the inside of a comer is recognized. (qp is set in parameter
1711.)
When an inner corner is recognized, the feedrate is overridden in the range
of Le in the block immediately before the intersection of the corner and Ls
in the next block following the intersection.
Ls and Le are each a straight line connecting the intersection of the corner
and a given point on the path of the cutter’s center.
Ls and Le are set in parameters 1713 and 1714.
An override is applied from point a to b.

1722 Rapid traverse feedrate reduction ratio for overlapping rapid traverse blocks
[Data type] Byte axis
[Unit of data] %
[Valid data range] 1 to 100
This parameter is used when rapid traverse blocks are arranged
successively, or when a rapid traverse block is followed by a block that
does not cause, movement. When the feedrate for each axis of a block is
reduced to the ratio set in this parameter, the execution of the next block is
started.
