Adaptive Feed & Depth Parameters
Chapter 32
32-13
Important: This depth sensor travel limit is not an absolute value. As
such, the overall probe deflection allowed is dependent on where the
operator determines the probes’ zero point to be. Make sure this parameter
is small enough to compensate for any offset the operator may enter when
the probe zero point is established.
When your total probe deflection reaches the value entered for this
parameter an error is displayed on the CRT and the control enters cycle
stop. This error can be monitored in PAL using the $ADPSTA flag. You
can monitor the adaptive depth probe position using the axis monitor
screens (see your 9/Series Integration and Maintenance Manual).

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.
Often the accuracy of the adaptive depth probe resolution is higher then the
resolution of the axis encoder. In these cases it may be desirable to allow
the adaptive depth probe to supply position feedback and close the axis’
position loop after the probe has tripped.
Selecting the From Axis option with this parameter will cause the servo
position loop to be closed by the adaptive depth controlling axis encoder
for all moves. G26 adaptive depth moves will use probe feedback only to
determine the actual depth of the hole. Positioning accuracy is limited to
the resolution of the feedback for the adaptive depth controlling axis.
