10.6 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 PN 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:
