9.6 Resonance suppression

9.6 Resonance suppression
The resonance suppression function is filter (notch filter) function. It detects mechanical
resonance at a frequency between 250 Hz and 1500 Hz, and decreases the gain of specific
frequency (by automatically setting notch filter) to suppress the mechanical resonance.
Now four current setpoint filters are available for the V90 servo drive. Filter 1 is lowpass filter.
Filter 2, filter 3 and filter 4 are band damp filters.
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
