Additional tables can be set-up, e.g. for axes Y and Z:
MD18342 $MN_MM_CEC_MAX_POINTS[2] = 90 (Table 3: Axis Y, positive traversing
direction)
MD18342 $MN_MM_CEC_MAX_POINTS[3] = 90 (Table 4: Axis Y, negative traversing
direction)
MD18342 $MN_MM_CEC_MAX_POINTS[4] = 50 (Table 5: Axis Z, positive traversing
direction)
MD18342 $MN_MM_CEC_MAX_POINTS[5] = 50 (Table 6: Axis Z, negative traversing
direction)
4.4.5 Extension of the sag compensation with NCU link - only 840D sl
Application
If a system is operated with NCU link, any number of axes of the NCU link grouping can be
compensated mutually. The two axes that are coupled via sag compensation must be
interpolated on one NCU.
