Collision monitoring in Automatic operation
The TNC monitors motions blockwise, i.e. it outputs a warning in the
block which would cause a collision, and interrupts program run. A
reduction of the feed rate, as with Manual Operation, does not occur.
The handwheel superimpositioning function with M118 is
not possible in combination with collision monitoring.
If collision monitoring is on, the TNC shows the symbol
in the position display.
If you have deactivated the collision monitoring, the symbol
for collision monitoring flashes in the operating-mode bar.
The M140 (see “Retraction from the contour in the tool-
axis direction: M140” on page 303) and M150 (see
“Suppress limit switch message: M150” on page 307)
functions might cause non-programmed movements if the
TNC detects a collision when executing these functions!
