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 must you define the touch point position. 
In many touch probe cycles you can also define a setup clearance in 
addition that is added to Machine Parameter 6140.
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.
