NOTE
When a value of ”0” is set as the character code, ”AI APC”
blinks.
For other parameters, see the description of ”Parameter” in the subsection
describing AI contour control.
NOTE
1 Some parameters of functions unavailable for the Series
21i–M may be described. For whether each function is
available for the Series 21i–M, refer to the descriptions and
other manuals.
2 For AI advanced preview control, bits 5 (MI0) and 6 (MI1) of
parameter No. 7050 and bit 0 (NMI) of parameter No. 7052
do not need to be set.
See the description of ”Alarm and message” in the subsection describing
AI contour control.
See the description of ”Caution” and ”Notes on using custom macros” in
the subsection describing AI contour control.
The AI high–precision contour control function is provided for
high–speed, high–precision machining such as metal die machining in
programs containing continuous minute straight lines and NURBS curve
commands. This function enables suppression of acceleration/
deceleration delays and servo delays that become larger with increases in
the feedrate.
This function can be used to make the tool follow the specified values
faithfully, reducing machining profile errors and executing high–speed,
high–precision machining.
The function can perform finer acceleration/deceleration than
conventional high–precision contour control to increase the machining
speed.
AI nano high–precision contour control allows nano–interpolation to be
used together with all functions of AI high–precision contour control.
