Function and
operation
After the software option has been enabled, collision monitoring is
permanently active in the Manual, Positioning with Manual Input, Program
Run Single Block, Program Run Full Sequence, smarT.NC and El. Handwheel
operating modes. You can switch collision monitoring off in the Manual
operating mode in the "Collision Monitoring (DCM)" menu that appears when
the Collision soft key is pressed. It is possible to activate/deactivate DCM
separately here for the manual and the program-run modes of operation.
At the same time, individual objects can be deactivated at run-time (see
"Activating and deactivating monitoring" on page 1439), or generally be
excluded relative to other objects via the description table (see "Collision
exclusions" on page 1436).
In the Manual and El. Handwheel operating modes, the iTNC reduces the
speed of the traverse motions when objects monitored for collision come into
proximity, in order to avoid a collision. This can result in sudden reductions or
increases of the feed rate to the maximum permitted speed in the respective
manual operating modes. If the objects come within a specified distance of
each other, the control stops the machine’s motions and outputs an error
message. The control makes a distinction between two different zones, which
are indicated visually.
 Early warning
• No message, axes can still be moved
• Brown frame around the graphical depiction of the kinematics; the
affected objects monitored for collision are colored brown
• Cause: The iTNC reduces the traversing speed in order to safely prevent
a collision
• Solution: Remove the cause of the danger, or retract the axes from the
danger zone.
 Error
• Message example: DCM: Spindle - RoundTable
• Meaning: Two objects monitored for collision are within approx. 4 mm
of each other.
• Cause: Distance is less than 4 mm [between 0 and 4 mm]
• Solution: The axis can be moved again if the motion increases the
distance between the collision objects (for example by pressing the
axis-direction key for the opposite direction): First release the axis-
direction key or stop the handwheel, and then press the appropriate
axis-direction key or turn the handwheel in the appropriate direction.
Acknowledging the error message with the CE key is then not
necessary.
