386 Programming: Special Functions
11.2 Dynamic Collision Monitoring (Software Option)
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 in
combination with collision monitoring is only possible in
stopped condition (blinking control-in-operation symbol).
If collision monitoring is on, the TNC shows the
symbol in the position display.
If you have deactivated collision monitoring, the symbol
for collision monitoring flashes in the operating-mode bar.
Danger of collision!
The M140 (see “Retraction from the contour in the tool-
axis direction: M140” on page 372) and M150 (see
“Suppress limit switch message: M150” on page 376)
functions might cause non-programmed movements if the
TNC detects a collision when executing these functions!
