Use the Adaptive Depth probe feature to enable an adaptive depth probe
that monitors tool depth relative to the actual part surface. This feature

allows:

a more flexible part mounting system (small changes to part size or part
mounting do not require reprogramming of the machine or station)

greater accuracy with a less accurate machine drive system (tool
position is relative to the part surface rather than the machine home)

a retroactive change in axis positioning resolution (feedback for axis
positioning switches between the normal axis encoder and the adaptive

depth probe once the probe is triggered).

Important: Since the adaptive depth probing feature requires one

feedback port to pass probe position data to the control and another

feedback port for normal axis positioning feedback, the adaptive depth

feature is not compatible with the single axis 9/230 processor which only

has one feedback port.

The adaptive depth probe is wired like any A quad B rotary encoder. It is

connected to one of the controls feedback ports. Table 4C.E lists

specifications for an encoder. These same specifications apply to your

adaptive depth probe.

If you are using the adaptive depth probe to close the position loop

(selected in AMP) the maximum axis speed calculations from Table 4C.E

also applies. Refer to your AMP reference manual for details on other

configuration required to operate using an adaptive depth probe.
