Precision stop OFF G8

G8 switches Precision stop off. The block containing G8 is executed
without a Precision stop.

Precision stop blockwise G9

G9 activates a Precision stop for the NC block in which it is
programmed. With a Precision stop, the control does not run
the following block until the last point has been reached in the
tolerance window for position. The tolerance window is defined in
the posTolerance machine parameter (no. 401101).

Switch off protection zone G60

G60 is used to cancel protection zone monitoring. G60 is
programmed before the traversing command to be monitored or
not monitored.
Parameters:
Q: activate/deactivate – Self-locking=1
0: Activate protection zone (modal)
1: Deactivate protection zone (modal)
Application example: With G60, you can temporarily deactivate a
programmed monitoring of the protection zone in order to machine
a centric through hole.
