Note:
If, on a transition from continuous path control to exact stop, the path of the transition block is
shorter than the required deceleration distance, the velocity is immediately reduced to zero by
function G09.
Alarm 3092 ”Programmed speed too high” is displayed.

4.2.7.2 Continuous path operation G62/G64
The preparatory function G64 is used if no relief cutting is to occur at transitions from block to
block. This function also causes transitions to be smoothed when changing the direction of
movement. When applying a dry run feedrate with G64, the dry run feedrate is used both
during the block and at the end of the block. The programmed feedrate value is not used.
