Acceleration control and exact stop/continuous path
11.7.1
Exact stop/continuous-path control mode: G9, G60, G64
Functionality
G functions are provided for optimum adaptation to different requirements to set the traversing behavior at the block borders
and for block advancing. For example, you would like to quickly position with the axes or to machine contours over multiple
blocks.

Exact stop G60, G9
If the exact stop function (G60 or G9) is active, the velocity for reaching the exact end position at the end of a block is
decelerated to zero.
Another modal G group can be used here to set when the traversing movement of this block is considered ended and the
next block is started.
● G601 Exact stop window fine
Block advance takes place when all axes have reached the "Exact stop window fine" (value in the machine data).
● G602 Exact stop window coarse
Block advance takes place when all axes have reached the "Exact stop window coarse" (value in the machine data).
The selection of the exact stop window has a significant influence on the total time if many positioning operations are
executed. Fine adjustments require more time.
See the following illustration for comparison of the G60 and G64 velocity behavior:
