Use the Adaptive Depth feature to e nable an adaptive depth probe that
monitors tool depth relative to the actual part surface. This feature is
sometimes referred to as “cut to length”or “cut to depth”. This feature
allows a more flexible part mounting system (small changes to part size or
part mounting do not require reprogramming of the station) and a less
accurate machine drive system (tool position is relative to the part surface
rather than the machine home). The system installer can determine in
AMP i f the position loop, for moves that use the adaptive depth feature, is
closed by the axis encoder or the adaptive depth probe.

The should know the following terms which are used throughout this
discussion on adaptive depth:
Term: Definition:
Adaptive DepthProbe T his isthe mechanical device usedto measure the locationofan axis relative
tosome surface.
Adaptive DepthAxis Th e controlling axis thatisconfiguredtobe positioned bytheadaptivedepth
probe. The adaptivedepthprobe is typicallymechanicallyconnected to the
adaptive depth axis.
TriggerToleranceforProbe This is the amountof probe deflection necessarytoindicate the adaptive
depth probehas fired.
MaximumProbe Deflection This is the AMPedtravel limits fordeflectionoftheadaptive depth probe.
Thisdoes notinclude anyprobedeflectionthatoccurs beforethe probefired
isindicated.
Probe Fired Thisindicates the depth prove hasrecorded more feedbackcountsthen the
triggertoleranceand these haveoccurred beyondthe probezeropoint.
Probe Zero Point T his isa location established by touching offtheadaptive depth probe to the
partorestablishedatpowerturn on. Ittypically aligns the tip ofthe adaptive
depthprobewiththedrilling tool tip.
Adaptive DepthFeedback Source This isthe devicethatcontrols the positioningoftheadaptive depth axis.
Typically this isanencodermounted to the motorshaft fornormal moves,
