Collision monitoring in the manual operating
modes

In the Manual and Electronic Handwheel operating modes, the TNC
stops a motion if two objects monitored for collision approach each
other within a distance of less than 3 to 5 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.

Keep these constraints in mind:

„

The handwheel superpositioning function with M118 in
combination with collision monitoring is only possible in
stopped condition (blinking control-in-operation symbol).
To be able to use M118 without limitations, you have to
deselect DCM either by soft key in the Collision
Monitoring (DCM)

menu, or activate a kinematics model

without collision monitored objects (CMOs).

„

With the “rigid tapping“ cycles, DCM works only if the
exact interpolation of the tool axis with the spindle is
activated through MP7160.

„

At present there is no function by which DCM can
prevent collisions before machining of a workpiece
begins (e.g. in the Test Run) operating mode.

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.
