3.6.3 Axes in position
When 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
the control voltage is switched on.
The markers will only be reset by the NC if the axes leave the positioning window when being
traversed in manual operation or automatic operation. This is also valid when passing over the
reference marks.
The "Axis in position" markers are not set for contours which can be machined at constant feed rate.
