The moment of inertia ratio that is
calculated here is used in other
tuning functions.

Autotuning with
Host Reference
The following parameters are
automatically adjusted with the
position reference input from the
host controller while the machine
is in operation.
You can use this function for fine-
tuning after you perform auto-
tuning without a host reference.
n Gains (e.g., position loop gain
and speed loop gain)
n Filters (torque reference filter
and notch filters)
n Friction compensation
n Anti-resonance control
n Vibration suppression

Custom Tuning The following parameters are
adjusted with the position refer-
ence or speed reference input
from the host controller while the
machine is in operation.
