7.10 Exact Stop Check Mode; G61
Function and purpose
Whereas the G09 exact stop check command checks the in-position status only for the block in
which the command has been assigned, the G61 command functions as a modal. This means that
deceleration will apply at the end points of each block to all the cutting commands (G01 to G03)
subsequent to G61 and that the in-position status will be checked. G61 is released by
high-accuracy control (G61.1), automatic corner override (G62), tapping mode (G63), or cutting
mode (G64).
Command format
G61 ;
In-position check is executed in the G61 block, and thereafter, the in-position check is executed at
the end of the cutting command block is executed until the check mode is canceled.
