Setting The Zero Offset - Siemens SINUMERIK 840D sl Operating Manual

Procedure
4.4.3

Setting the zero offset

You can enter a new position value in the actual value display for individual axes when a
settable zero offset is active.
The difference between the position value in the machine coordinate system MCS and the
new position value in the workpiece coordinate system WCS is saved permanently in the
currently active zero offset (e.g. G54).
Relative actual value
Further, you also have the possibility of entering position values in the relative coordinate
system.
Note
The new actual value is only displayed. The relative actual value has no effect on the axis
positions and the active zero offset.
