2.2.1 Example

### In incremental mode:

Using the lower figure, let us imagine we wish to make a part in which three holes have to be drilled with the coordinates stated. It is clear that the blueprint will only reflect the incremental coordinates (I) or the absolute ones

(ABS) referring to the part zero (point "0" in the figure) although the DRO also shows them with respect to home (Io).

After referencing the axes, as was described in the previous section, we can make this part in incremental or absolute mode according to whether we chose a type of dimensions (I) or (ABS) of the blue-print.

15.000

25.000

22.600

-Press this key until the ABS LED is turned off.

-Move the axis up to the face of the part to set it as part zero.

At this point, one can proceed in two ways:

-Preset the axis with a zero value by pressing this keystroke sequence:

[22.600

[22.600] -Move the axis towards the first position until the DRO reads: 22.600. or...

-Preset the axis with a value of 22.600 by pressing this keystroke sequence.

In case of a mistake, press this key to cancel it and leave it as it was.

Pressing this key displays the previous preset value.

[0.000] - Move the axis towards the first position until the DRO reads: 0.000.

This last method turns out to be more practical as after selecting the destination coordinate one only has to remember to move the axis until the

V0612 - 20i-T / 30i-T - Installation/Operation - DRO operation - (7/32)

[25.000]

ABS

[0.000] - Once this turning operation has concluded, one can go to the next position, after having preset the next coordinate (25.000), by moving the axis until the display reads 0.000.

- And so on until all the turning operations are concluded.

### Note:

By pressing this key until the ABS LED lights up, the DRO will show the real position of the axis with respect to part zero "0"

### In absolute mode:

ABS

-Press this key until the ABS LED is turned on.

ABS

-To preset part zero:

-Place the axis exactly over “0” and press:

At any time, by pressing this key, the DRO will display the present position with respect with the previous zero (ABS led on).
