MACHINE AND POWER CONNECTION
2.4 REFERENCE SYSTEMS
The machine where the VNP400 DRO will be used must have the following reference and
datum points defined for each axis:
*
Machine Zero Point or home. It is established by the manufacturer or operator as the
origin of the machine’s coordinate system.
*
Part Zero or absolute zero point (datum points). The part’s measurements are
displayed with respect to this point when working with absolute coordinates.
This DRO can store up to 9 part zeros being possible to recall and use them any time.
*
Incremental (Floating) Zero Point. The part’s measurements are displayed with
respect to this point when working with incremental coordinates.
It is possible to associate an incremental Zero point to each one of the 9 absolute zeros
set previously plus another one for the Machine Reference Zero (home).
Once the desired Part Zeros and Floating zeros have been set, the DRO will store in memory
their positions with respect to home (in pairs).
When a new home search is carried out, the DRO assumes that point as the new home and
it recovers the absolute and incremental zeros corresponding to each of the 9 references
(REF 1 thru REF 9). REF 0 is Machine Reference Zero (home).
These references are kept in memory even when the DRO is powered off.
2.4.1 ABSOLUTE AND INCREMENTAL COORDINATES
The VNP400 allows the displaying of two different coordinate types.
*
Absolute coordinates. Position coordinates referred to Part Zero.
*
Incremental coordinates. Position coordinates referred to the incremental (floating)
zero point.
