Move lag error G718
G718 prevents the automatic updating of nominal control position
values with the axis position data (e.g. when traversing to a fixed stop,
or after canceling and re-enabling a controller release).
Application:
Before activating a master-slave axis coupling.
Actual values in variables G901
G901 is used to transfer the actual values to the variables V901 to
V920.
The function generates an interpreter stop.
Zero-point shift in variables G902
G902 writes the shift in Z direction into variables V901 to V920.
The function generates an interpreter stop.
Lag error in variables G903
G903 transfers the current following error (distance by which the
actual values lags the nominal value) into the variables V901..V920.
The function generates an interpreter stop.
Block speed monitoring off G907
The CNC PILOT starts traverse paths requiring spindle revolutions
when the programmed speed has been reached. G907 is used to
deactivate speed monitoring block by block. The path of traverse is
started immediately.
Program G907 and the traverse path in the same NC block.
Parameters
Q On / Off
„ Q=0: Off
„ Q=1 on, the servo lag stays saved
Use G718 only in “expert programs.”
