1.5 Coordinate System
SW4000 DRO is an instrument which can measure position of work piece when processing.
Coordinate system must be definite first for more efficiency and accuracy.
YZ plane
XZ plane
XY plane
X
ZY
In horizontal plane, the X axis is parallel with the operator; Y axis is perpendicular to X axis. Z-axis is
perpendicular to horizontal plane. Positive direction of axis is set as the figure. It also can be changed as
customer.
The value of one point position is the distance relative to the origin of coordinate.
For a work-piece as Figure A, the value of each point position is as the Figure B when point O is the origin
of coordinate.

Chapter 2 BASIC OPERATION
2.1 Power on
Function: Power on then SW4000 enter normal display state.
It can memorize the following parameter after power on.
A. The scale position where power off;
B. ABS/INC/SDM mode;
C. Shrinkage is enabled or disable;
D. Metric/Imperial mode;
The origin of the linear scale must be searched again if the scale is moved when power off.
Note: Normal display state
The state DRO automatically enters after on or exit from “STEUP”. In normal
display state, X window,Y window and Z window displays the current value of
X axis, Yaxis and Z axis separately. The message window displays “ABS”,
“INC” or “SDM XXX” (indicate the Number of SDM coordinate, with a range
of 000—999).When user switch among ABS/INC/SDM, MM/INCH or shrinkage / Un-shrinkage, DRO will not
leave this state. When you enter CALCULATOR function, input data to X (or Yor Z) axis, function of searching
the Reference point (RI) of the linear scale or special function (BHC: BHL:ARC: SLOPE PROCESSING and
EDM function): DRO is not in the normal display state.
2.2 Zeroing
Function: Zero the designated axis in normal display state. Zeroing is used to set the current point as datum
point.
Note: 1 The axis can’t be zeroed when DRO is in other states (for example: in the state of calculating function
or in special function). DRO should return normal display state;
2 The axes can be zeroed in ABS/INC/SDM states;
3 When zero in ABS coordinate, INC display value is cleared simultaneously. Zeroing in INC
coordinate has no effect on ABS and SDM display value.
4 Press the zero key of the same axis will cancel above zero operation
if the scale kept still after zero.
5 zero is means that set the current point as the origin point of current axis.
Example 1:Set the point O (as the figure illustrated) as datum
STEPS:
1) Return normal display state;
2) Move the machine table: and align the lathe tool with point O.
The DRO displays as the right figure.
3) Press to zero X axis,

Press to zero Y axis.
2.3 Preset Data to designed axis
Function:Preset a value to current position for a designed axis in normal display state.
NOTES: 1 Axis can not be preset while the DRO is in other states (e.g. calculating function or special function).
DRO should return normal display state before presetting data.
2 Axis can be preset in ABS/INC/SDM state.
3 In SDM state, input mode “0” means that the display value is equal to the enter value; input mode
“1” means that the display value is equal to the negative of enter value.
4 The range of input value is that the minimum value to the maximum value which could be displayed
in the designated window.
Example: Machine the work-piece from the figure (a) to figure (b), and the plane C
is the datum and counting direction is right.
STEPS:
1. Move the machine table, and align the lathe tool to plane B.
2Return normal display state;
3Press X, “0” is flashing in X window, waiting for entering a data;
4Press 10+-in turn, which means the preset data is “-10”;
If incorrect value is inputted: press

2.9 Search the Absolute Reference Point of Scale (RI)
Function: An absolute datum should be set when a work-piece is machined. There are two cases:
When the machine table is going in high speed, the machine
table can’t stop immediately but continue going further because
of inertia when power is off suddenly. There will be distance ∆L
between the actual position and the position in the DRO
memorize. That is to say the display value is not the actual value
of the position when power is on again.
If the machine table is moved without intention when DRO is
off.
How to restore the preset ABS and correct display value?
These questions can be solved easily with this function of search RI.
STEPS:
1. DRO is set in ABS coordinate.
2. Press RI , then the message window displays “SELAXIS”;
3. Select the axis which need search RI. For instance: select Y axis, then
press Y. “FD.Y REF” is displayed in message window, and Y
window flashes.
4. Move the machine table. The buzzer sounds when RI is searched, then
Y window stops flashing and displays the value of the current
position, the DRO returns normal display state.
In the course of searching, press
AC
to quit this operation.
The machine table is moved when DRO is off. How to restore the former absolute ABS coordinate
and correct display value?
Take SW4000-2 as an example.
STEPS:
1）This operation (searching the absolute origin point of the
scale) is necessary when a linear scale is installed or the
default parameter is loaded. Or the ABS coordinate would
not be restored.
2）Set the point O as the datum of ABS. (Move the machine

3）table until the lathe tool is aligned with point O, and zero
the X axis, Y axis)
3) The machine table is moved when power is off;
4) Power on, switch to ABS coordinate. The DRO maybe
displays as the right.
5) Search the RI of X axis and Y axis. After RI is found, the
ABS coordinate is restored.
6) Align the lathe tool with point O, “0.000” is displayed in
X window and Y window, which means the point O is the
origin and the ABS coordinate is restored.
NOTE:
The linear scale has a RI every 50 mm. For the sake of search identical RI, move the scale around the red
mark “ ” to search RI.△
△△
△
Setup correct RI mode is a premise.
2.10 Clear the Error message
If ERROR message is enabled, the message window will display “E1” if the signal of phase A and
phase B of the linear scale changes at the same time; the message window will display “E2” if the linear
scale runs too fast; the window will display “E3” if these two conditions occur simultaneously. When error
information appears, the display value has an error of 1-2 count. So users need search RI to restore ABS
coordinate. If you think that doesn’t affect your work, press
AC
to clear error message and continue your
work. .
Example : When signal of A phase and B phase is same in Y
axis the window displays as the right figure.
Press
AC
to clear the error information. Y window
displays the value, but it is error. The difference between the
display value and the true value is about 1- 2 times of
resolution. For instance, the resolution of scale is 5µm; the
difference is 5-10µm.
2.11 Lathe Function
As the right figure, if two scales are installed
in one axis, the position of the work-piece should
be the sum of these two values (X+Y) in this

direction. It is called lathe function.
A. lathe mode 0: normal display (the lathe
function is disabled).
B. lathe mode 1: X window value = the value of X axis position + the value of Y axis position.
C. lathe mode 2: X window value = the value of X axis position + the value of Z axis position.
STEPS:
1. Set the lathe mode in initial system settings;
2. In normal display state press (three axes display) or
Y
X

disabled and the LED is off);
3. In lathe state, press (three axes display) or Y
X+ (two axes display) to exit the lathe function:
and the LED turns off.
A. If in normal display state: the value of the position is as the
right.
B. In lathe mode 1, the DRO will display as the following:
X window display value = value of X axis position +
value of Y axis position
C. In lathe mode 2, the DRO will display as the
following:
X window display value = value of X axis position +
value of Z axis position
2.12 Filter display value
When machine a work-piece by grinder, the display value varies quickly due to the vibration of
grinder. User can’t see display value clearly. SW4000 series DRO provides display value filter function to
disable the quake change of display value.
STEP:
1) Enter display value filter function.
In normal display state, press N

Chapter 3 1000 groups SDM coordinate
SW4000 has three display modes: the absolute mode (ABS), the incremental mode (INC) and the
1000 groups second data memory (SDM 0—SDM999).
ABS datum of the work-piece is set at the beginning of the processing and the 1000 group SDM is
set relative to ABS coordinate.
1000 group SDM coordinate can be divided into several segments, and every segment stores data of
one work-piece. If one segment has 20 groups SDM coordinate, DRO can be divided into 50 segments
and can store data of 50 work-pieces.
SDM 000 ------ SDM 019 data of the first work-piece
SDM 020 ------ SDM 039 data of the second work-piece
SDM 040 ------ SDM 059 data of the third work-piece
……
SDM 960 ------ SDM 979 data of 49th work-piece
SDM 980 ------ SDM 999 data of 50th work-piece
Example:The ABS datum is the center point O,
the point E, F, G, H needed processing are set
as datum of SDM 000 —SDM 003.
Two ways to set SDM coordinates:
1) Zeroing at the current point.
2) Presetting datum of SDM coordinate.
3.1 Zeroing at the Current Point
At first set the center point of the work-piece as the origin of the ABS, then align the lathe tool with
point E, F, G, H by moving the machine table and zero them. It is the position to process where the “0.00”
appears in X window, Y window by moving the machine table whether in ABS or in SDM coordinate.
STEPS:
1. Set the center of rectangular point O as the datum of ABS
Make line AB parallel with X axis: line AD parallel with Y axis.
When position lathe tool to point O
Zero X axis and Y axis in SDM 000;
Zero X axis and Y axis in SDM 001;
Zero X axis and Y axis in SDM 002;
Zero X axis and Y axis in SDM 003;
2. Set the point E as the datum of SDM 000.
SDM 000: align the lathe tool with point E and zero
X axis, Y axis. DRO displays as the right.

3. Set the point F as the datum of SDM 001.
In SDM 001 and align the lathe tool with point F,
then zero X axis, Y axis. DRO displays as the right:
Press ,
4. Set the point G as the origin of SDM 002.
In SDM 002, align the lathe tool with point G, and
zero X axis, Y axis. DRO displays as the right.
Press ,
5. Set the point H as the origin of SDM 003.
In SDM 003, align the lathe tool with point H, and
zero X axis, Y axis. DRO displays as the right.
Press , ;
6. Machine the work-piece according to the preset SDM coordinate;
7. Machine another work-piece according to the same blueprint. You only need set the center point
as the datum of ABS. It is not necessary to set SDM coordinate again, as SDM can be set
automatically. Point E, F, G, and H is the zero point of SDM 000, SDM 001, SDM 002, and SDM
