SELF-TESTING
A general test of the instrument is carried out each time it is switched on, and the validity
of the data stored in the memory is checked. If these are found to be reliable, while the
function is being performed the following wording will appear on the display for a few
seconds:

ABSOLUTE/INCREMENTAL COUNT
The LED of each Axis always signals the following:
AXIS LED ON
= AXIS IN ABSOLUTE COUNT (ABS) MODE
AXIS LED OFF
= AXIS IN INCREMENTAL COUNT (INC) MODE
AXIS LED WILL FLASH
= FUNCTION BEING PERFORMED
It is possible to switch either a single Axis or all the Axes from one counting mode to the
other as follows :

The LED will light up (or extinguish) and signal that the Axis is in the ABS (or INC) mode.
The counting system is managed by the instrument, which has a dual internal counter
(ABS/INC) for each Axis. The information relating to the movement of the Axis updates
both counters at the same time. The information entered by the operator, on the other
hand, only affects the counter of the selected counting system. It goes without saying that
if the ABS counter is reset at a given point of the travel (ORIGIN) and the INCREMENTAL
counting mode is used (this is handier and more versatile to use), the operator can then
carry out all the resetting, pre-selections, functions and so on required by the machining
process, since he can return to the ABS count at any time to find out the
“absolute”
positions of the Carriages at that time and thus find the ORIGINS which had been set.
