ABS / INC Coordinates display switches
ES-3 ABS
INC
provides two sets of basic coordinate display, they are (absolute)
and (incremental) displays.
During machining operations, the operator can
The operator is then free to zero the axes or preset any dimensions into any
axis in INC coordinate for relative position machining. The work piece datum
( work piece zero position ) is still retained in ABS coordinate by the ES-3.
Operator can then toggle between ABS (absolute) and INC (incremental)
coordinates without losing the work piece datum ( work piece zero position ).
store the work piece datum ( zero
position ) in ABS coordinate, then switch to INC coordinate to continue machining
operations.

Centre-find
-6-
Purpose : ES-3 provides the centre-find function by halving the current display coordinate, so that the zero point
of the work piece is located at the centre of the work piece.
Step 3 :
To set the X Axis zero point at the centre of the work piece.
Example :
Then half the display coordinate using centre-find function as per follows:
Step 1 : Locate the edge finder at one end of the work piece, then zero the X Axis.
Step 2 : Locate the edge finder at the opposite
end of the work piece.
Now the X Axis zero point ( 0.000 ) is located at the X centre of the work piece.

ref datum memory
-7-
Easson Easson

During the daily machining process, it is very common that the machining cannot
be completed within one working shift, and hence the DRO has to be switched
off, or less commonly, a power failure occurs whilst machining which leads to
loss of the work piece datum ( work piece zero position ). The re-establishment
of work piece datum using edge finder or other method inevitably introduces
machining inaccuracies, because it is not possible to re-establish the work piece
datum exactly at the previous position.
To allow the recovery of work piece datum very accurately, with no need to
re-establish the work piece datum using an edge finder or other methods, every
transducer has a reference point location to provide a datum point memory function.
The working principal of the ref datum memory function is as follows.
-There are a permanent and fixed mark (position) on the transducer,
normally called mark or point..
Since this point position is permanent and fixed, it will never change or
disappear when the DRO system is switched off. Therefore, we simply need to
store the distance between the point and the work piece datum ( zero
position ) in DRO's memory. Then, in case of the power failure or the ES-2 being
switched off, we can recover the work piece datum ( zero position ) by presetting
the display zero position as the stored distance from the point.

provides one of the most easy-to-use datum memory function.
There is no need to store the relative distance between the mark and your work datum
zero into the ,
In daily operation, operator simply needs to locate the mark position whenever they switch on
the to let it know where the mark position is, then will automatically do the work
datum storage on its' own . In the case of a power failure or the being switched off, the
operator can recover the work piece datum easily by using the procedure.

function : In ref datum memory function, the will automatically store the relative
distance between the mark position and the work piece datum ( zero position )
whenever the operator alter the zero position, such as zeroing, centre find,
co-ordinate preset or etc...
Therefore, the needs to store the mark position prior to any machining
operation. So that the loss of the work piece datum ( zero position ) is avoided during
any accidential or unexpected events, such as power failure or etc.. it is recommend that
the operator finds the ref mark position using the ( ) function whenever
he switches on the .

ES-3 ORIGINAL PARAMETER RESET FUNCTION
Some inscrutable cases or improper operations cause the chaos of parameter,
then you need to initialize the parameter to reset the system.
Operational procedure：
( ) Turn off the ES-3.
( ) Power on ES-3 once again, when "ES-3" moving in display window,
please press "8" key then ES-3 enters into the RESET function.

２
power on the DRO, then DRO
starts the self-test function
when "ES-3" appears in display window, please press " " key.
after press " " key, the wore "8" can appear and continuously nove in
display window.
(3). Wnen enter inyo the RESET function, the word "8" appears and continuously
moves in display window. After the word "8" moves 2 3 trips, the DRO will
complete the reset.
(4). Turn off the DRO after complete the reset, then power on DRO once again.
