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

2.4.3

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.
Resetting the relative actual value
The softkeys to set the zero point in the relative coordinate system are only available if the
corresponding machine data is set.
Precondition
The controller is in the workpiece coordinate system.
The actual value is set in the reset state.
Note
Setting the ZO in the Stop state
If you enter the new actual value in the Stop state, the changes made are only visible and
only take effect when the program is continued.
