can someone help me for an SL25 -FANUC 16T controller

[danby]

I am a cnc programmer and I have a problem with a FANUC 16T controller on a SL25 lathe, who don't have correct motion in circular interpolation .
I have controlled the servo parameters and are correct. Linear movements are correct and maintain the dimensions programmed in the cnc program. For circular movements, the axes have a motion according to the attached image, as if the center of the circle is not calculated correctly.
The company qualified my the program incorrectly, but after we did a test for the profile attached , we came to the conclusion that the machine does not correctly execute the circular interpolation.
If you have any suggestion regarding the circular motion error, and if is possible I fix that from the machine parameters, I'd be grateful to be able to fix the errors.



Thanks,
