5.6.2 Changing the settable work offset (G54 ...)
Function
$P_UIFR[]
This identifier can be used to alter a settable work offset in the
program.
Coarse offset
The value of the coarse offset is defined for the relevant axis.
Fine offset
MD 9451 WRITE_ZOA_FINE_LIMIT is programmed to set data limits
(absolute) for the fine zero point offset. The fine offset is displayed in
the "Settable work offset" display.
Activation of WO via MD MM_FRAME_FINE_TRANS.
5.6.3 Global work offset/frame
Function
In addition to the settable, programmable and external work offsets,
up to eight global work offsets/frames (basic WO) can be defined.
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.
Basic WO
(total basic frame)
In addition, eight 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).
Machine manufacturer
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.
