Limit value of movement that is executed at the normal direction angle of a
preceding block
[Data type] 2-word
[Unit of data]
Input increment IS-A IS-B IS-C Unit
Millimeter input 0.01 0.001 0.0001 mm

[Valid data range] 1 to 99999999
This parameter sets the limit value of movement at the normal
direction angle of a preceding block.
N1
Tool center path
N2
Movement
Programmed path
For straight line
Block N2 is machined with the tool being normal to block
N1 when the movement of N2 in the figure on the left does
not exceed the set value.
N3
Fig.4.27 (a) When the Block Moves Along a Straight Line
Diameter
Programmed path
Tool center path
For arc
rc N2 is machined with the tool being normal to
block N1 when the arc diameter of N2 in the figure on
the left does not exceed the setting value. A normal
direction axis is not controlled to move in the normal
direction according to the arc movement.
