ACTFBACK(axis)
The CNC uses this mark when the system has einternal feedback. See machine
parameter FBACKSRC.
The CNC sets this mark high (=1) to indicate that the external feedback (direct feedback)
is being used . The CNC sets this mark high (=0) to indicate that the internal feedback (motor
feedback) is being used .
The feedback type may be swapped from the PLC using the mark FBACKSEL(axis). See
"FBACKSEL(axis)" on page 431.
TANGACT(axis)
The CNC sets this mark high (=1) to indicate that tangential control is active in the axis. The
CNC sets this mark high (=0) when freezing (suspending) or canceling the tangential control
of the axis.
LOPEN(axis)
The CNC activates this mark to inform the PLC that the axis position loop is open.
MAXDIFF(axis)
This mark is used on gantry axes. The CNC activates this mark when it cannot correct the
position difference between the master axis and the slave axis because the difference is
greater than the value set in machine parameter MAXDIFF. Position correction must be
enabled in machine parameter DIFFCOMP.
