Critical angle subtended by two blocks for automatic corner deceleration
[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–based automatic corner deceleration function is used.
The angle subtended by two blocks is defined as q in the examples shown
below.
