9.4.8 Speed Feedback Compensation
The speed feedback compensation can be used to reduce vibration and allow a higher speed loop gain to be set. In
the end, the speed feedback compensation allows the positioning settling time to be reduced because the position
loop gain can also be increased if the speed loop gain can be increased.
When this function is used, it is assumed that the moment of inertia ratio set in Pn103 is correct. Verify that
the moment of inertia ratio has been set correctly.
