Collision monitoring in the manual operating modes
In the Manual operation and Electronic handwheel operating
modes, the control stops the movement if two objects monitored
for collision approach each other within a distance of less than 2
mm. In this case, the control displays an error message naming the
two objects causing collision.
Before the collision warning, the control dynamically reduces the
feed rate of the movements to ensure that the axes stop in good
time before a collision.
If you have selected a screen layout in which the collision objects
are on the right, then the control additionally marks the colliding
objects in red.
When a collision warning has been issued, machine
movements via the axis direction keys or the handwheel
are only possible if they increase the distance between
the collision objects.
With active collision monitoring and a simultaneous
collision warning, no movements are permitted that
reduce the distance or leave it unchanged.

Monitoring (DCM) function.
