BEL In AI advanced preview control or AI contour control mode:
0 : Linear acceleration/deceleration before look–ahead interpolation is
used.
1 : Bell–shaped acceleration/deceleration before look–ahead interpolation
is used.
NOTE
To select look–ahead bell–shaped acceleration/
deceleration before interpolation, the option for look–ahead
bell–shaped acceleration/deceleration before interpolation
is required.
