Resonance suppression with one-button auto tuning (p29021=1, p29023.1=1)
The resonance suppression function is used together with the one-button auto tuning
function. The function is activated by default.
The function can be activated/deactivated with bit 1 of p29023.
Before you use the resonance suppression function with one-button auto tuning, make sure
the load is mounted as required and the servo motor can rotate freely. When the one-button
auto tuning process completes successfully, the servo drive automatically sets the following
notch filter relevant parameters with actual machine characteristic. Four current setpoint
filters can be activated at most. You can check the following parameters in the tuning result
window.
