With these parameters the required velocity
for approaching
the reference points can be selected. The approach
speed and direction
have an influence on the accuracy of the reference signal evaluation.

With parameter 59 the axis sequence for reference point approach is determined.
Care should be taken that the tool axis is traversed away from the workpiece
first.

With these parameters, the traversing direction
when approaching
the reference points is determined
in relation-
ship to the "reference
end position"
dog. Depending on the location of the reference point on the scale, the
dog for the "reference
end position"
can be fixed at the end of the axis in the plus or minus direction
in
relationship
to the counting directions
and in accordance with the "right-hand
rule".
