As the drill plunges into the
drilling surface, the controlling
axis’ position registers are
decreasing (Z10 to Z5).
Enter minus for this example.

Notes
This parameter applies to the adaptive depth probe.
Function
This parameter is used with the adaptive depth feature. Refer to your
9/Series Mill Operation and Programming Manual for details on this
feature. This parameter is only available on mill control types.
With an adaptive depth probe occasional misfires can occur as some
erroneous probe deflection is detected when the adaptive depth axis
accelerates/decelerates or simply from axis vibration. This is typically
dependant on mechanical features like probe sensitivity, machine
configuration and rigidity, etc..
To avoid these probe misfires this parameter allows you to enter a dead
band. This dead band is the amount of deflection the probe can return to
the control without registering a probe trip.
