Further information
G60, G9
G9 generates the exact stop in the current block, G60 in the current block and in all following
blocks.
Continuous-path mode commands G64 or G641 - G645 are used to deactivate G60.
G601, G602
The movement is decelerated and stopped briefly at the corner point.
Note
Do not set the limits for the exact stop criteria any tighter than necessary. The tighter the limits,
the longer it takes to position and approach the target position.
G603
The block change is initiated when the control has calculated a set velocity of zero for the axes
involved. At this point, the actual value lags behind by a proportionate factor depending on the
