Limit value of movement that is executed at the normal direction angle of a pre-
ceding block
[Data type] 2–word
[Unit of data]
Increment system 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.4.28 (a) When the Block Moves Along a Straight Line
Diameter
Programmed path
Tool center path
For arc
Arc 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.
