Collision monitoring in the manual operating modes

In the

Manual Operation and El. Handwheel operating modes,

the TNC stops a motion if two objects monitored for collision

approach each other within a distance of 1 to 2 mm. In this case,

the TNC displays an error message naming the two objects causing

collision.
If you have selected a screen layout in which positions are

displayed on the left and collision objects on the right, then the

TNC additionally marks the colliding objects in red.

Once a collision warning is displayed, machine

motions via the direction keys or handwheel are

possible only if the motion increases the distance

between the collision objects. For example, by

pressing the axis direction key for the opposite

direction.
Motions that reduce the distance or leave it

unchanged are not allowed as long as collision

monitoring is active.
