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 338) and M150 (see

"Suppressing the limit switch message: M150" on page

342) functions might cause non-programmed movements

if the TNC detects a collision when executing these

functions!
