DIN/ISO: G247)
Effect
With the DATUM SETTING cycle you can activate as the new datum
a preset defined in a preset table.
After a DATUM SETTING cycle definition, all of the coordinate inputs
and datum shifts (absolute and incremental) are referenced to the new
preset.
Status display
In the status display the TNC shows the active preset number behind
the datum symbol.
Please note before programming:

When activating a datum from the preset table, the TNC
resets the active datum shift.
The TNC sets the preset only in the axes that are defined
with values in the preset table. The datums of axes
marked with — remain unchanged.
If you activate preset number 0 (line 0), then you activate
the datum that you last set in a manual operating mode.
Cycle 247 is not functional in Test Run mode.
