4.7 Resonance suppressions
When the mechanical system has the resonance effect, it is possibly created by higher
rigidity of the servo system and quicker response. It may improve if reduce the gain. The servo
driver provides the low pass filter and the notch filter. Under unchanging the gain by using filters
can achieve the effect of resonance suppression.
The parameters related to Resonating suppression as follows:

The principle for suppression resonance is to use filters to suppress the resonance peak that the
machinery responds. The schematic drawing is as follows:
