FUNCTIONS
B–64144EN/01
354
This function is designed for high–speed, high–precision machining.
This function can be used to reduce a delay caused by
acceleration/deceleration or a delay in the servo system, which would
grow as a feedrate increases. As a result, machining profile errors become
smaller, if any.
This function can also be used to enable look ahead linear
acceleration/deceleration before interpolation for up to 15 blocks, thus
allowing smooth acceleration/deceleration across multiple blocks and
faster machining.

Q 1 : AI advanced preview control mode on
Q 0 : AI advanced preview control mode off
NOTE
1 Please command G05.1 with an independent block.
2 AI advanced preview control mode is released by the reset.
This function becomes enabled when AI advanced preview control mode
is entered.AI advanced preview control mode is also called AIAPC mode.
The following functions become effective in the AI advanced preview
control mode
1) Multiple blocks look ahead linear acceleration / deceleration function
before interpolation (Maximum 12 blocks)
2) Automatic corner deceleration function
3) Feedrate clamp based on acceleration function
4) Feedrate clamp based on arc radius function
5) Block overlap function (5 blocks)
6) Advanced preview feed forward function
(1)Look ahead linear acceleration / deceleration before interpolation
When feed per minute is specified, this function reads maximum 12
blocks ahead to perform linear acceleration / deceleration before
interpolation, that is, to apply acceleration / deceleration to the specified
feedrate.
When acceleration / deceleration after interpolation is used, acceleration
/ deceleration is applied to the interpolated data. Consequently, the
interpolated data is changed by acceleration / deceleration. However,
when acceleration / deceleration before interpolation is used, acceleration
/ deceleration is applied to the feedrate data before interpolation.
Consequently, the interpolated data is not changed by acceleration /
deceleration. Accordingly, interpolation data ensures that the machining
follows a specified line or curve at all times, thus eliminating the
machining profile errors that result from delays in acceleration /
deceleration.
