Cautions
CAUTION
1 If the total distance of the advanced preview blocks
decreases below the deceleration distance from
the current speed, deceleration starts. If, at the end
of deceleration, advanced preview has proceeded,
increasing the total distance of blocks, acceleration
is performed again. If blocks, especially those with
small travel distances, are specified in succession,
the speed may not become constant because
deceleration and acceleration are performed
alternately. If this occurs, decrease the specified
speed.
2 If, during axial movement, the dry run signal
changes from "0" to "1" or from "1" to "0,"
acceleration/deceleration is performed to the
predetermined speed without deceleration to speed
0.
3 If, in AI contour control mode, there is a block
without movement or a 1-shot G code command
such as G04, the tool decelerates and stops
temporarily in the previous block.
Notes
TE
1 Acceleration before interpolation used must be of
the linear or bell-shaped type. Exponential
acceleration/deceleration cannot be used.
2 During switching to AI contour control mode,
manual handle interrupts are disabled.
3 This function is limited to X-Y plan machining.
It cannot be used together with cylindrical
interpolation, normal direction control,
three-dimensional machining function, etc.
