Hi AllI have a problem with a machine using servos. It is a 4 axis machine with the 4th axis being rotary. The linear servos are tuned and working very well but the rotary axis is not behaving well. It has a severe oscillation and I cannot seem to get the PID trimmed to stabilize the servo.
The 4th axis used to be a stepper and that worked well but we changed the stepper for a servo to get more speed through a reduction planetary gearbox.
I attached the HAl and INI files. Maybe I missed the obvious againThe setup is like this: I use a 5i23 with two H Bridges from Mesa. Remaining ports has a 7i33 and a 7i37 to drive the 4th axis servo and do some I/O.
