Fig. 3−12 Measuring systems for absolute positioning and zero point shifting
Shifting of machine zero
Purpose
l The reference run is to be carried out on one side of the traversing range when it is too time
consuming to approach the machine zero.
Function
l Via the home position (C1227) the machine zero point is shifted with regard to the reference
point. The home position is set at the reference point so that with a positive home position the
machine zero point is situated in negative direction.
l The home position (C1227) will only be accepted as actual home position" when being in
reference run" or set reference point" mode.
l The effective actual home position" is indicated under C1220/8 and C1221/8.
