ZERO OFFSETS
The VNP400 allows the setting of up to 9 absolute (Part Zero) and 10 incremental (floating)
zero offsets in order to use the coordinates relative to the part drawing without having to
modify the particular coordinates of the various points of the part.
Once the absolute and incremental zero offsets have been set, the DRO will store, in pairs,
their positions with respect to home.
This way, every time a new reference is selected (REF 0 thru REF 9), the DRO recovers
the absolute and incremental offsets corresponding to that reference.
The absolute position values displayed will be referred to the corresponding absolute zero
offset and the incremental position values to the incremental zero offset.
To set any of these zero offsets, follow these steps:
*
The DRO must not display any window superimposed on the screen. If this is not
the case, press
*
Select by means of function CHANGE REFERENCE the reference corresponding
to the zero offset to be set.
*
Select absolute or incremental zero offset mode by means of the ABS/INC softkey.
*
Move the machine to the point to become the new absolute or incremental zero offset.
*
Press the RESET softkey to set this point as zero offset for that axis.
Repeat this operation for the rest of the axes.
The DRO will assume this point as the new Part Zero Offset or Floating Zero Offset.
Note:
It is not possible to preset the absolute zero offset (Part zero) corresponding to REF
0 since it always coincides with home.
