2.5.1 Zero offsets

After reference point approach, the actual value display for the axis coordinates is based on the
machine zero (M) of the machine coordinate system (MCS). The program for machining the
workpiece, however, is based on the workpiece zero (W) of the workpiece coordinate system
(WCS). The machine zero and workpiece zero are not necessarily identical. The distance
between the machine zero and the workpiece zero depends on the workpiece type and how it is
clamped. This zero offset is taken into account during the program execution and can be a
combination of different offsets.
When setting up the workpiece, set the workpiece zero as zero offset, e.g. G54. Using the Zero
offsets softkey, open the list where you can select various views using the vertical softkeys.
Active
zero offsets, for which active offsets are included or for which values, settable zero offsets
and total zero offset are entered
Overview
The active offsets or system offsets are displayed for all set-up axes. In addition to the offset
(course and fine), the rotation, scaling and mirroring defined using this are also displayed.
Base
The defined channel-specific and global base offsets, divided into coarse and fine offsets, are
displayed for all set-up axes.
G54..G57
All of the settable offsets, divided into coarse and fine offsets, are displayed along with
rotations, scaling and mirroring.
