Danger
The offset is applied the next time the parts program is started.
Function
In addition to the settable, the programmable and the external work
offsets, it is possible to define up to 16 global work offsets/frames
(basic WO). This allows offsets, scales and mirrors to be defined
simultaneously for all channel and machine axes.
The global work offsets (NCU-global frames) apply uniformly to all
channels. They can be read and written from all channels. The
activation is performed in the relevant channel.
In addition, 16 channel-specific basic work offsets can be defined in
each channel. The global and channel-specific frames are combined
to produce a total basic frame (basic WO).
Recommendation:
Use the 3rd basic offset onwards for your own applications. The 1st
and 2nd basic offsets are reserved for setting the actual value and the
external work offset.
With global frames there is no geometrical relationship between the
axes. It is therefore not possible to perform rotations or program
geometry axis identifiers.
In SW 5 and higher, the settable work offset and the basic work offset
are represented in one table. You can edit the values in this table.
You can switch between the values of the individual axes.
For all work offsets, you can display either the defined offsets (coarse
and fine) or the specified rotations, scales and mirrors for each value.
