8. Tuning
Regarding Learning control, you don’t need to tune parameters basically.
But servo system needs to be stable before the application of Learning control. If oscillation occurs, you need
to make stable by tuning Load inertia ratio (No.2021), Acceleration feedback (No.2066), Tcmd filter (No.2067),
Observer function (No.2003#2), and etc.
