On the cutting machines with the PLC size system and the size bar. 

For some reasons or cases,  such as sudden power outages, prolonged use of the machine, or accidental hits, the size system may become inaccurate. 

What should we do?

for example,  we put target  size  150mm,  but we got 151mm.

firstly got a real distance from the guide to the blades like this picture

Then get into the parameter with the password，

"correction"-> password 8-> put real distance.

 Put the real distance, which  you got at the first step，Into the “correction value”，

Then put “blade thickness” and “speed” as the picture showing， Click “correction input”，

 Then click，"Limit position" the yellow button,You will get into the other page

Check whether this page with the same minimum and maximum data，If not ,you put the same, and “return” .

"Maximum" should be 

600mm for 1200,

 900 for 1800,

 1350 for 2700mm ...

This is the whole process to reset the data into your system, please try,  let me know the result
