2.5 ABS and INC Conversion
he DRO gets two sets of standard coordinate system,namely ABSAbsolute
and INC Relative Coordinate.ser could set the zero point of workpiece in ABS
coordinate,then switch to INC coordinate for machining.Zeroing at any position
in INC coordinate would not affect the length value from zero point to current
point in ABS coordinate.he process in ABS would change according to the
machining status.ser could switch the coordinate back to ABS for checking.
ress ABSINC button to switch.

1. Linear Compensation
·Axis:
Select the axis for setting.
·Comp. Type:
Select the compensation type(Linear or Non-linear)
·Backlash:
Only the encoder type has een set as -Rotary ncodthere could e set.
·Actual Length:
ress numeric utton to input the actual moving length of tale.This
length value is getting from more accurate measuring instrument than
linear scale.
·Comp. Value:
ress numeric utton to input the compensation value.
Note: Formula for compensated value:
Compensation Value =
(Actual length-DRO Displayed length) / (Actual Length/1000) mm/m
Compensation range: -1.9mm/m to +1.9mm/m
Take  axis as an example (same operation to other axis)
ove the tale of  axis direction for 1000.000mm of actual moving length.
The displayed value on DRO is 999.0mm.
The calculation of compensation value is like the elo:
Compensation Value=(1000.000-999.0)/(1000.000/1000.000)=0.120
Step 1: Confirm the starting point
ero the value of  axispress the CO utton to enter the function.
Then set the axis to e .
Step 2: Select the compensation type
ress don direction utton to sitch the compensation type setting
and select it as Linear Compensation.

Or select the compensation value to input 0.120.
Note hen selecting to input the actual measuring length.e need ero the

·Comp. Length
Press numeric button to input the actual length of every segment.This
length should be get from more accurate measuring instrument.
·Start Point
Press set button to select
the start point.
(Endpoint or mechanical
reference point of linear scale)

Page 13
2. Fundamental Function
Non-linear compensation function takes the mechanical reference point or
endpoint of linear scale as the starting point.The DRO will compensate the
displayed value according the input err list.Please note Linear compensation
and Non-linear compensation function could not be used at the same time.
The DRO gets two ways for non-linear compensation.
1. Take the linear scale end point as the starting point for compensation.
(Figure 1)
2. Take the first mechanical zero reference point of linear scale as the
starting point for compensation.(Figure 2)
Take X axis setting as an example(same operation to other axis)
Step 1 Press the COMP. Button to enter the compensation function,and select
the axis as X.
Step 2 Select the compensation type to be Non-linear.
Step  Input the Compensation segments as 6.
Step  Input the compensation length for every segment as 10.000
Step  Select the starting point as the endpoint of linear scale.
And press ENT to go for next .
Step 6 Move the table of X axis direction to one of the endpoint,and press
ENT to confirm the point.(When the start point has been set as
mechanical reference point of linear scale,once the point has been
captured,the DRO will enter next step automatically).

Step 8: Repeat the operation of step 7 to complete all segments.Once the
compensation finished,the RO will eit compensation automatically.
Note: When the start point has been set as endpoint,the data in REF function
will be cleared.Only the start point has been set as mechanical reference
point,the REF and non-linear compensation could be used together.
3. Backlash Compensation
his setting could be set with the condition of encoder has been set 3-Rotary
Encod.ress the numeric button to input the compensation alue.

3.1 Grid Hole Function
This function is for drilling equal hole on vertical and horizontal direction.Once
operator input the required parameter,the DRO will calculate the position of
each hole,and set the coordinate of each hole to be (0.000,0.000).Operator
could move the table to the target position for machining the hole.
There are two ways for grid hole function:
1. Length way:Input the total length of the line
2. Step way:Input the length between two holes
Press the grid hole function button to enter the interface.
Press up and down direction button to select the parameter for setting.
