Datum Setting
If you want to save the datum points in nonvolatile
memory, you must first cross over the reference
marks.
Only after crossing over the reference marks can you set new
datums or activate existing ones.
Datum Setting
There are several ways to set datums:
Touch the edge of the workpiece with the tool and then set
the desired datum. You can also touch two edges and set the
centerline between them as a datum, or touch the inside of a
circle and set the circle center as a datum (see examples).
The tool data of the tool used for this are automatically
considered (see “Tool Compensation”).
In P70, you can select:
• Two datum points: The selected datum
is displayed via 1 or 2
• Nine datum points: The selected datum
is displayed in the lowest axis via d1 to d9.
Press the datum key (“d” blinks).
Enter a datum number (1 to 9).
