The gain decreasing frequency, width as well as depth can be set by setting the notch filter:
Using the resonance suppression function
Note
The resonance suppression function is used together with the auto tuning function. In real-
time auto tuning and one-button auto tuning mode, 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 following parameters:
• For one-button auto tuning: bit 1 of p29023
• For real-time auto tuning: bit 6 of p29024
Resonance suppression with one-button auto tuning (p29021=1, p29023.1=1)
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 real machine characteristic. Four current setpoint filters
can be activated at most.
