Non-Linear Compensation
Non-linear compensation function enable users to input the non-linear err
compensation value in the DRO to improve the accuracy of machining.This
function is applicable to machines which have high requirement of
accuracy.(Boring machine,Grinding machine...etc)
Non-linear compensation function takes the mechanical zero reference
point of linear scale as the origin point of machine.The DRO will compensate
the displayed value according the input err list.Each axis has a maximum 40
points for compensating.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)
0 10 20 30 40 50

Starting point is the end point of
linear scale(most right or most left)

Parameter setting
(Take X axis as an example.Same operation to Y and Z axis)
Step 1: In DRO system parameter setting,set the compensation type to be
Non-linear compensation.Press when DRO is under self-checking
process.Press to select XYZ-COMP.Press to set compensation type
of X axis to be non-linear compensation.Press to exit the system
parameter setting.Operations are shown as below:
