6.3.6. Resonance suppression unit
(1)
Automatic high-frequency resonance suppression
Due to the limitation of the mechanism, Resonance may occur when the response
bandwidth of control system is too large, and this may cause damage on the mechanism.
Usually this phenomenon can be improved by increasing the rigidity of the mechanism or
reducing the bandwidth of the system, but it will increase the cost and reduce the response.
To suppress resonance without increasing the cost and reducing the bandwidth, this servo
drive provides Automatic High-frequency Resonance Suppression. its related parameters,
setting ranges and default values are shown in the below table. It mainly provides five groups
of resonance suppression filters and one group of low-pass filters to suppress resonance,
the user can manually or automatically operate as below instructions.
