1779
Critical angle subtended by two blocks for automatic corner deceleration (for
look–ahead control)
[Data type] 2–word
[Unit of data] 0.001 deg
[Valid data range] 0 to 180000
Set a critical angle to be subtended by two blocks for corner deceleration
when the angle–basedautomatic corner deceleration function is used.
The angle subtended by two blocks is defined as θ in the examples shown
below.

Block A (G01)
Block B (G01)
Angle subtended by two straight lines
Block A (G02)
Block B (G01)
Angle subtended by an arc and its tangent
