Information
Another group of G functions exists for moving into the position (see Section "Exact
stop/continuous-path control mode: G60, G64"). For G60 exact stop, a window with various
precision values can be selected with another G group. For exact stop, an alternative
instruction with non-modal effectiveness exists: G9.
You should consider these options for adaptation to your positioning tasks.
