19. HIGH SPEED CUTTING
FUNCTIONS
B–63614EN/01
380
NOTE
1 When this function is used, the option of the AI advanced
preview control is needed. And when there is the AI
advanced preview control option, it is possible to specify the
look–ahead control (G08 P1).
2 The deceleration of the axis is started when the total travel
of the axis in the blocks read in advance is less than the
distance required to decelerate the axis from the current
feedrate. When the total travel of the axis in the blocks read
in advance increases at the end of deceleration, the axis is
accelerated. When blocks specifying a short travel are
specified in succession, the axis may be decelerated, then
accelerated, then decelerated, and so on, resulting in an
unstable feedrate. In such a case, specify a smaller feedrate.
3 When the dryrun signal changes from 0 to 1 or from 1 to 0
during the axis movement, the feedrate accelerates or
decelerates to the commanded velocity without the
deceleration to 0.
4 When a block without movement or one–shot G–code such
as G04 is specified in the AI advanced preview control
mode, the deceleration stop is done at the previous block.
5 In case of using the acceleration / deceleration after cutting
feed interpolation, please use linear type or bell–shaped
type. It is not possible to use exponential type.
6 During changing to the AI advanced preview control mode,
the manual handle interruption becomes ineffective.
