Dynapath, "in position range" parameter....

Group,
I'd like a little more insight into the "in position range" parameter
on my Dynapath Delta 20M contoller.
a little background...last week my controller began halting program
execution when it was failing to get the in position indication on
the Y axis as it approached the target position from one direction.
It only happened approaching the target coordinate from one
direction. I tuned the servo and made sure the ways were getting
plenty of lube (auto oiler). Still seemed to do it. Then I went
into the control's parameters and increased the in position range
from .0005" to .001". The combination of all my efforts made the
problem go away (at least for 4+ hours of running yesterday).
While the problem was happening the screen indicated the axis was at
it's target position, right down to the last tenth, but it still gave
that in position hang up.
My question is, exactly how does the control use that in position
range value?
Thanks,
Doug
