Activating handwheel during G33
With the G923 function you can activate the handwheel in order to
make compensations during a thread cut. In the G923 function you
define limits within which traverse with the handwheel is possible.
Cycle stop—the Steuerung retracts the tool from the
thread groove and then stops all tool movements. (Lift-
off distance: OEM configuration parameter:
