hi, recently we bought fiber laser with X, Y1, Y2 axis driven by Panasonic MINAS-A6 servos. Problem is that when we cut circle the shape is rather oval. All other shapes are perfect. CW direction cut makes deformation to the right side, CCW cut makes deformation to opposite side.
We think the problem is in synchro between X, Y1 and Y2. Therefore we downloaded parameters from all three drives to make a backup and found some differences:

param. X Y1 Y2
00-002 0 4 4
00-004 240 200 200
00-013 264 251 251
00-016 0 1 1
01-001 800 900 900
01-004 100 25 25
02-000 0 1 1
02-007 5000 213 248
02-009 0 30 18
02-022 28 11 11
05-014 0 10 10
05-022 264 251 251
05-025 264 251 251
05-026 264 251 251
06-005 0 220 220
06-006 100 200 200

I can provide also operational manual with all parameters however it is 45MB. (MINAS A6 Series Operating Instructions)

we tried lots of things on our own but this is for sure above our possibilities.

Anyone can help?

thank you

Ladislav
