10. Segmented error compensation
Notes: only in Metric system can do Segmented error compensation .
After Segmented error compensation, the display can be converted freely
between Metric system and Imperial system.
There are two methods for Segmented error compensation of the digital
readout
1. To carry out error compensation taking the start point as the mechanical
origin. (Figure 1)
2. To carry out error compensation taking the 1st absolute zero of the raster
ruler as the mechanical origin. (Figure 2)
L: The distance of effective range of raster ruler
L1: Length of the compensation segment
L2: Effective distance of the compensation segment
1. The parameter set-up method is as follows: (the operation methods of Y-axis
and Z-axis are the same as X-axis）
1) Move the raster ruler to the smallest end of
the coordinate, and enter into “ALE” right-angle coordinate system.
2) Press enter into the function of segment compensation of X axis, and
input related parameters.
3) Set the segment compensation

Remarks: both of the two modes enter into the finding of the mechanical
origin, only the segmented compensation can enter into the compensation
interface after find the reference point
4）Find the mechanical origin
5）There are two methods for setting the compensation origin,
after the machine origin interface is confirmed.
1. Press to choose the current position as origin, and directly enter into
the set of step 5 compensation,
2. Press to confirm the absolute zero of the linear scale is the
mechanical origin, move the linear scale in positive direction
and find the the absolute zero and enter into the compensation interface.
Move towards the positive direction of X axis of the
machine tool and search for the 1st absolute zero of the raster ruler as the
mechanical origin. After find the origin, then auto enter the next step for data input.
This time the X-axis displays the raster ruler real value, and Y-axis displays the
empty compensation, the input value is displayed on the Y-axis.
5) Input the compensation setup of the 1st segment
At this time, firstly move the X-axis raster ruler
towards the positive direction.
When the raster ruler is moved close to the compensation value
Press

displays the standard value or the
measurement value by laser.

ruler and machine tool set up together. If the raster ruler or digital readout whose
Segmented compensation value is set up in a machine tool is moved to another
machine tool, the Segmented compensation value needs to be reset. When the
Segmented compensation function is not needed, the Segmented compensation
value is to be canceled. The cancellation method is:
Enter into the set of Segmented compensation, and press to quit to cancel
the former set compensation value when entering into the compensation value
input page.
3. Methods of finding mechanical origin
If there is power off when the raster ruler is moving, or the rater ruler is
moved before the power is on, after re-start, the mechanical origin needs to be
found again. Because of the movement in power off or before power on, the
coordinate origin of the machine tool can not match the value in the digit display
meter. If the mechanical origin is not found, the misplaced relationship is brought
into the later user coordinate system. As when calculating the user coordinate, the
Segmented compensation value is found according to the wrong mechanical
coordinate, thus there will be big error of the displayed coordinate.
The method of finding mechanical origin is as follows:
1. Move the raster ruler to the position which is initially set up as the
mechanical origin, and then enter into the select page of Segmented compensation.
Choose FIND_ZE and press to the interface for choosing compensation method,
press , the interior of digit display meter handles automatically. At this time,
finish finding the mechanical origin and quit the absolute coordinate system
automatically.
2. Firstly move the raster ruler to the smallest value, and enter into the
Segmented compensation page, choose FIND_ZE, press to enter into the
interface for choosing compensation method, press
Enter X axis to find the status of absolute zero. Move the raster ruler towards
the positive direction. When the absolute zero is found, it is the mechanical origin.
Automatically back to absolute coordinate system after above finished.
Advise: find the mechanical origin before start work after power on to
assure the coordinate origin of the machine tool can match the value in the
digital readout.

11. Linear Error Compensation
The linear error compensation function is used to make the linear correction
of the system error of the grating metering system.
Correction factor S =(L-L')/(L/1000) mm/m
L---the actually metered length (mm)
L'---the displayed value on digital display meter (mm)
S---the actually factor (mm/m), "+" symbol means the actual length is larger, and
"-" symbol means the actual length is smaller.
Compensation range: -1.500 mm/m～+1.500 mm/m
Example: The Actual metered length of the machine tool machine table is 1000
mm, and the display value on the digital display meter is 999.98 mm.
S=(1000-999.98)/(1000/1000)=0.02 mm/m
1) Select the axis
2) Press
modificatory coefficient used
last time
3) Press the new correction factor in:
4) Press
Note: The linear error compensation can only be carried in absolute display
mode (the message screen displays ALE) and metric system；
12. Power Interruption Memory
During the processing of a working piece, there may occur power interruptions or
needed temporary turnoffs, the digital display box will automatically store the
working state (such as the working mode in every axis, displayed data and the
linear error compensation factor) just before every interruption event in its
memory. Every time when the machine is turn on again, the digital display box
will recover to its working state just before the interruption event after self
checking, and the valve just before the interruption (turn off) event will recover,
and the processing will continue.
