20.7 Deselecting axes referencing
For axis examinations it is possible to deselect referencing in MP1340.x.
8 Enter the value 0 (= no evaluation of the reference mark) for the axis concerned or for all axes.
DANGER
Non-referenced axes have no relation to the machine datum. Software limit switches may be at a
wrong position.
Traversing these axes bears the risk of a crash!
Note
MP1340.x contains the sequence in which the reference marks are traversed.
This means, if the sequence is ...
 MP1340.0 : 3
 MP1340.1 : 2
 MP1340.2 : 1
... first the 3rd axis is referenced (e.g., Z axis), then the 2nd axis (e.g., Y axis) and subsequently
the 1st axis (e.g., X axis).
If you now want to deselect the X axis, you have to enter 0 in MP1340.2.
Normally however, the reference run is deselected for all axes.
