Precision stop off G8
G8 switches precision stop off. The block containing G8 is executed
without
a precision stop.
Precision stop G9
G9 activates a precision stop for the 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 a configuration parameter
("ParameterSets PX / PZ > CfgControllerTol > posTolerance").
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.
Application example:
With G60, you can temporarily deactivate a
programmed monitoring of the protection zone in order to machine a
centric through hole.
Actual values in variables G901
G901 transfers the actual values of all the axes of a slide into the
variables for the interpolation information.
See G904 Page 373.
Zero-point shift in variables G902
G902 transfers the zero-point shifts into the variables for the
interpolation information.
See G904 Page 373.
Lag error in variables G903
G903 transfers the current following error (distance by which the
actual values lags the nominal value) into the variables for the
interpolation information.
See G904 Page 373.
