CSD In the function for automatically reducing a feedrate at corners,
0 : Angles are used for controlling the feedrate.
1 : Differences in feedrates are used for controlling the feedrate.
LS2 Acceleration/deceleration after interpolation for cutting feed in the
advanced preview control mode
0 : Exponential acceleration/deceleration
