13.2 Before you start working with
touch probe cycles
To make it possible to cover the widest possible range of applications,
machine parameters enable you to determine the behavior common
to all touch probe cycles.
Maximum traverse to touch point: MP6130
If the stylus is not deflected within the path defined in MP6130, the
TNC outputs an error message.
Safety clearance to touch point: MP6140
In MP6140 you define how far from the defined (or calculated) touch
point the TNC is to pre-position the touch probe. The smaller the value
you enter, the more exactly you must define the touch point position.
In many touch probe cycles you can also define a safety clearance that
is added to MP6140.
Orient the infrared touch probe to the
programmed probe direction: MP6165
To increase measuring accuracy, you can use MP 6165 = 1 to have an
infrared touch probe oriented in the programmed probe direction
before every probe process. In this way the stylus is always deflected
in the same direction.

If you change MP6165, you must recalibrate the touch
probe, because its deflection behavior changes.
