Main group 7/subgroup 0: Change of program and machine reference
points
@706
With command @ 706, a position is specified, referred to the machine zero, and
approached from the specified axis. The command is effective only in the block in which it
is specified.
As many axes can be specified as can be traversed simultaneously by the NC. The
positions of the axes to be approached are programmed either in DIN code or by means of
the command @ 440 ... .
The command @ 706 suppresses all zero offsets (settable, settable additive,
programmable and external) as well as the PRESET and DRF offsets.
In order to approach a fixed machine point, the tool offsets must also be deselected.
If machine data 5007.1 has been set, G53 acts like @ 706.
If the machine data has not been set, the PRESET and DRF offsets are also suppressed
with G53.
Example:
@706 X1000 Z500 The programmed traversing paths in X and Z are
approached referred to the machine zero.
