5156 ILLEGAL AXIS
OPERATION
(AICC)
In the AI contour control/AI nano contour
control mode, the controlled axis selection
signal (PMC axis control) changed.
In the AI contour control/AI nano contour
control mode, the simple synchronous
axis selection signal changed.
5157 PARAMETER 0
(AICC)
The setting of the parameter for specifying
the maximum cutting feedrate (No. 1422,
1432, or 1420) is 0.
The setting of the parameter for specifying
acceleration/deceleration before interpola-
tion (No. 1770 or 1771) is 0.
1) This function requires the AI contour control function or AI nano
contour control function option.
When the AI contour control function option is installed, the
look–ahead control function (G08P1) can also be specified. When the
AI nano contour control function option is installed, the AI contour
control function and advanced preview control function (G08P1) can
also be specified.
2) When the total distance of blocks read in advance reaches the distance
for decelerating from the current feedrate, deceleration is started.
When look–ahead operation proceeds and the total distance of blocks
increases by termination of deceleration, acceleration is started again.
If a series of blocks with a small amount of travel are specified, the
deceleration and acceleration may be alternated, which prevents the
feedrate from being constant. In this case, specify a lower feedrate.
3) When the dry run signal is inverted from “0” to “1” or from “1” to “0”
during movement along an axis, acceleration/deceleration is
performed to the specified feedrate without deceleration to feedrate 0.
4) If a non–movement block or one–shot G code command such as G04
is found in the AI contour control/AI nano contour control mode, the
movement is decelerated and temporarily stopped in the preceding
block.
5) For acceleration/deceleration after interpolation, use linear or
bell–shaped acceleration/deceleration. Exponential acceleration/
deceleration cannot be used.
6) This function cannot be used together with the three–dimensional
cutting function.
