(c) Establishing the datum
When you reset the display in absolute mode, you are setting the current position of your machine as your
datum point. All absolute positions will be measured relative to this datum.
To set the datum position, move the machine to the point you intend to establish as the datum and then
reset any, or all, axes while in the absolute mode.
5.3 Digifind
Digifind is a reference function used to find the datum should it be lost due to power failure or an accidental
key stroke.
(a) Using Digifind to re-establish a lost datum
In the event that the datum positions are lost, align each axis to within ±6
mm
(±0.25”) for Spherosyn or
±2.5
mm
(±0.098”) for Microsyn to the original datum point.
By pressing the
[ ref
o
]
followed by the corresponding axis key, the display will update to a distance equal to
the distance from the current position to the datum point.
Each time the DPG2000 is powered up the cabinet will automatically use Digifind to compensate for any axis
movement of up to ±6
mm
(±0.25”) for Spherosyn and ±2.5
mm
(±0.098”) for Microsyn.
5.4 Inch/Millimetre
To change between inch and millimetre readings, press
[ in/mm ]
. The displayed data will be converted
instantly. The LED beside the key reminds you which mode is being used.
When you switch on the DPG2000, it will display the same unit of measurement which was set prior to
power loss.
