compensation.
Basic parameter of every axis’ error compensation of screw pitch includes as follows:
1. Reserve.
2. Backward checking points.
It is set for points number of compensation in negative direction.
3. Forward checking points.
It is set for points number of compensation in positive direction.
4. Multiple.
It is set for rate of compensation, also actual value=set value * multiple .
5. Distance (um).
It is set for the distance between two compensate points.
Note: Number of compensation points can be set freely, max points of each axis is 300.
B) Set compensation value (No. Coor(mm) Value(um) ):
In the area of setting compensation value, it will shows the value of compensation and every
axis’ error compensation point of screw pitch. Press “↑ ↓ PgDn PgUp” to select current
compensation point and press “Enter” to popup a dialog box to import the value of current
compensation point.
Test program generation automatically
Automatic generate a program of laser interferometer to check the screw compensation. Enter
the screw compensation screen and set basic parameters well, press “B” key to check program” to
detect program to popup a dialog box and press “Enter” to generate corresponding checking
program of screw compensation.
System calculates the distance of compensation points automatically according to basic
parameter. Distance is uniform, which could be set according to different axis, and user can set
compensation value of each point (System requires input absolute value, relating to value of datum
point).
Example1: Linear axis: when length of travel is -400mm~+800mm, distance is 50mm:
Basic parameters set as follows:
1)Backward checking points: 8
2)Forward checking points: 16
3)Multiple: 1
4)Distance(um): 50000
Corresponding compensation point and value:
No.
