3.6.2 Axes in position
If the axes have reached the defined positioning window (MP1030, see section "Positioning
window") after a movement, the "axis in position" markers are set by the NC. This also happens
after switching on the control voltage.
As soon as a positioning is started, the markers are reset by the NC. This is also valid when passing
over the reference marks. In the "Electronic handwheel" mode of operation the markers M2008 to
M2011 and M2017 are reset.
For contours which can be machined with constant feed rate the "Axis in position" markers are not
set.
