10.4 DATUM SETTING (Cycle 247, 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 datum shift, mirroring, rotation,
scaling factor and axis-specific scaling factor.
If you activate preset number 0 (line 0), then you
activate the datum that you last set in the Manual
Operation or El. Handwheel operating mode.
Cycle 247 is not functional in Test Run mode.

Cycle parameters

Number for datum?: Enter the number of the
desired datum from the preset table. Optionally you
can use the soft key SELECT and select the desired
datum from the preset table. Input range 0 to 65535

Status displays

In the additional status display (POS. DISP. STATUS) the TNC shows
the active preset number behind the datum dialog.
