Reference point
It is then specified how many compensating points must be supplied by means of the entered
spacing between 2 leadscrew error compensation points and the end stops at the machine.
Since leadscrew error compensation is only active when the axis is synchronized - at the
reference point - particular significance is attached to the compensation point coinciding with
the reference point. This compensation point is entered in encoded form in MD 316*. The
compensating value at this point must be 0.
Compensation point

NC MD 6000
MD 316 * 0
In view of the fact that the SINUMERIK 840C has a total of 1000 compensation points for all
axes, the control must be informed via MD 316* as to which of these 1000 points corresponds
to the axis reference point. The compensation point is not entered directly in MD 316*, the MD
offset (MD 6125 = MD offset = 125) being entered instead, so the reference point can only
be located on compensation points 1, 5, 9, 13, 17, ... .
