● 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.

Figure 1-22 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 Z10 ; Exact stop modal
N20 X20 Z0 ;G60 continues to act
N30 X30 Z-40
N40 M3 S1000
N50 G1 G601 X35 Z-50 F0.12 ; Exact stop window fine
N60 G64 Z-65 ;Switching over to continuous-path mode
N70 X40 Z-70
N80 G0 G9 Z-80 ; Exact stop acts only in this block
N90 X45 Z-90 ;Again continuous-path mode
N100 M30
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.
