Non-linear axis error compensation<br />
Working with non-linear axis error compensation<br />
To activate the non-linear axis error compensation you have to:<br />
Activate the function using working parameter P40 .<br />
Enter the compensation values in the table.<br />
Traverse the reference points every time you turn the machine<br />
on .<br />
Selecting the operating mode COMPENSATION VALUE<br />
TABLE<br />
In the COMPENSATION VALUE TABLE operating mode enter the<br />
compensation values for non-linear axis error compensation as follows:<br />
Press the "MOD" key.<br />
Select the "Code Number" soft key.<br />
Enter code number 105 296 and confirm with ENT.<br />
The <strong>POSITIP</strong> <strong>855</strong> automatically switches the position display to<br />
REF when the compensation value table is selected (the datum for<br />
the display is the scale reference point).<br />
The functions are in two soft-key rows and can be selected using<br />
the "paging" keys.<br />
Row 1: Enter the compensation value using the keyboard.<br />
Row 2: Read in or output the compensation value table using data<br />
interface.<br />
You can enter compensation values at 64 compensation points for<br />
each axis — as a function of the positions in the axis causing the<br />
error.<br />
Entering data<br />
Select the individual input fields with the arrow keys and enter:<br />
The axis which is to be corrected under "faulty axis?".<br />
Press axis soft key.<br />
The axis which is causing the error under "axis causing error?"<br />
Press axis soft key.<br />
The datum for the axis causing the error under "datum."<br />
The distance between the compensation points for the axis<br />
causing the error under "compensation point distance?" as an<br />
exponent to the base 2 :<br />
e.g. 14 = 2 14 = 16 384 µm.<br />
Compensation values: compensation point 0 is preassigned the<br />
value 0.000 and cannot be changed.<br />
Deleting the table<br />
You can delete the table values as follows:<br />
Select the table to be deleted under "faulty axis?" and press<br />
the axis soft key.<br />
Press "delete table."<br />
