Resonance suppression with real-time auto tuning (p29021=3, p29024.6=1)
The resonance suppression function is used together with the real-time auto tuning function.
The function is activated by default.
When you use real-time auto tuning function, you are recommended to disable the
resonance suppression function to get a high dynamic performance if there is no resonance
in the machine.
The function can be activated/deactivated with the bit 6 of p29024.
When you choose to use the resonance suppression function with real-time auto tuning, the
servo drive performs real-time detection of the resonance frequency and configures the
following notch filter relevant parameters accordingly:
Parame-
ter
p1663
p1664
p1665
p1666

Perform the servo on for the drive with host controller and tuning starts.
For example, you can use the following method to run the motor.
Implement servo on for the drive with Jog.
Enter the speed for the motor and press the direction button to let the motor run.
To achieve the desired system performance, you can change the dynamic factors or
related configuration parameters during tuning.
If the drive performance is acceptable, disable the tuning function by servo off and set
p29021 = 0.
Copy the tuned parameters from RAM to ROM to save them.
