2.1 Display modes

MM / INCH conversion
Fine / coarse resolution
Number of decimals
Decimal degrees / Degrees.Minutes.Seconds
Radius / Diameter
Notes:
Hysteresis or minimum position value

Part references (datum points)
[Ref number]
To display the position of the axes either in millimeters or inches by pressing
this key depending on whether the INCH led is off or on respectively.
To turn off the last decimal digit (coarse resolution) for cases in which fine
resolution is excessive, simply by pressing this key.
This keystroke sequence accesses parameter PAR53. The first digit
corresponds to the number of decimals to be displayed in mm and the second
digit in inches.
This key toggles the display format for the rotary axis [PAR00(4)=1] between
decimal degrees and Degrees.Minutes.Seconds.
When these models are used for measuring radii or diameters, one can
display twice the real displacement of the axis (diameter) by pressing this key.
The Φled will turn on or off to indicate the double or actual reading
respectively.
- This works in this way if bit 2 of installation parameter PAR04
(radius/diameter) of the axis has been preset as "1" (commutated).
When carrying out certain operations such as drilling hard material, EDM, etc.
the position display may fluctuate annoyingly.
In these cases, the operator can eliminate this oscillation by selecting the
"hysteresis" mode or the "minimum coordinate" mode just by pressing this
keystroke sequence to toggle from one mode to the other.
To have this option available, installation parameters PAR20 and PAR25
must be set accordingly.
There are 20 references or datum points that may be set for the part when
using absolute coordinates. The possible reference points (datum points) are
from 0 to 19. The 20i-M model shows the active reference on the display at all
times, whereas the 30i-M model only shows it when it is selected, after
pressing the reference key.
Selects the current reference. It will show the text "Select ref".
Key in the desired reference number and press [ENTER].
