Figure 10-20 Exact stop window coarse or fine, in effect for G60-G9; enlarged display of the windows
Programming example
N5 G602 ;Exact stop window coarse
N10 G0 G60 Z... ; Exact stop modal
N20 X... Z... ;G60 continues to act
...
N50 G1 G601 ... ;Exact stop window fine
N80 G64 Z... ;Switching over to continuous-path mode
...
N100 G0 G9 Z... ; Exact stop acts only in this block
N111 ... ;Again continuous-path mode
Remark: The G9 command only generates exact stop for the block in which it is
programmed; G60, however, is effective until it is canceled by G64.
Continuous-path control mode G64
The objective of the continuous-path control mode is to avoid deceleration at the block
boundaries and to switch to the next block with a path velocity as constant as possible (in
the case of tangential transitions). The function works with look-ahead velocity control over
several blocks.
For non-tangential transitions (corners), the velocity can be reduced rapidly enough so that
the axes are subject to a relatively high velocity change over a short period of time. This may
lead to a significant jerk (acceleration change). The size of the jerk can be limited by
activating the SOFT function.
