I am having some trouble tuning the servo on a new setup. It is using a Mesa 5i25-7i77 combo running Teknics SST-3100-U drives running in analog torque mode.
Where I am having the most trouble is on the Z and W axis. They are vertical, with no counter ballance driven by a lead screw. After a lot of effort tuning I have found that the PID error is not the same as f-error. The PID is showing very little error but the f-error is very proportional to the velocity. Why are the two errors no t the same? Any suggestions on ways to fix or improve it? O r a better idea of the source of the problem? here is a link to the discussion on the LinuxCNC Forum. http://www.linuxcnc.org/index.php/english/forum/10-advanced-configuration/24800-servo-tuning-advice/26154 http://www.linuxcnc.org/index.php/english/forum/10-advanced-configuration/24800-servo-tuning-advice/26154 -- ======================================== Todd Zuercher mailto:[email protected] ======================================== ------------------------------------------------------------------------------ Everyone hates slow websites.
