Display Active Zero Offset - Siemens SINUMERIK 840D sl Operating Manual

Figure 4-1
When the machine zero is not identical to the workpiece zero, at least one offset (base offset
or zero offset) exists in which the position of the workpiece zero is saved.
Base offset
The base offset is a zero offset that is always active. If you have not defined a base offset, its
value will be zero. The base offset is specified in the "Zero Offset - Base" window.
Coarse and fine offsets
Every zero offset (G54 to G57, G505 to G599) consists of a coarse offset and a fine offset.
You can call the zero offsets from any program (coarse and fine offsets are added together).
You can save the workpiece zero, for example, in the coarse offset, and then store the offset
that occurs when a new workpiece is clamped between the old and the new workpiece zero
in the fine offset.
Note
Deselect fine offset (only 840D sl)
You have the option of deselecting the fine offset using machine data MD18600
