(6/29) - DRO operation - Installation/Operation - 10i / 20i - V0703
2.2 Incremental, absolute and with respect to Machine Reference Zero
A DRO shows the current coordinates of one (10i)
or two axes (20i).
Coordinate means the distance from one point or position with respect with
another chosen as reference.
These DROs can display the position of the axes in incremental or absolute
mode or referring to home.
The next figure shows the different position display modes:
• In
Home mode
, it displays the distance from the current position of the axis
to the home point chosen in the feedback system (linear or encoder).
Press this sequence to access the
Home Search
mode.
(ABS)
• In
Absolute
(ABS), when the ABS led is on , it displays the distance from
the present position of the axis to part zero (D).
(I)
• In
Incremental
, when the ABS and "home" LEDs are off the distance from
the present position of the axis to the previous position is displayed.
Toggles between the ABS and incremental modes.
On the 20i model, it could occur that the installation parameter PAR11(1) has
been set to “0” for this key to independently affect each axis so that one axis
can display its position in incremental mode while the other does this in
absolute. In this case, to change the display mode for a particular axis, press
one of these two sequences.
