The function enables look–ahead linear acceleration/deceleration before
interpolation of multiple blocks. This results in smooth acceleration
/deceleration over many blocks, as well as high–speed machining.
G05.1 Q_ ;
Q1 : Start look–ahead control mode (multiple blocks are
read in advance)
Q0 : End look–ahead control mode (multiple blocks are
read in advance)
A block for specifying G05.1 must not contain any other command.
Simple high–precision contour control mode can also be canceled by a
reset.
When the dry run signal is inverted from 0 to 1 or from 1 to 0 during
movement along an axis, the speed of the movement is increased or
decreased to the desired speed without first being reduced to zero.
When a no–movement block or a one–shot G code such as G04 is
encountered in simple high–precision contour control mode, the
movement is decelerated and halted in the preceding block.
