Model-type damping filter
Outline
This function reduces vibration at the edge or over the entire equipment by removing the
vibration frequency components specified by the positional command.
The model-type damping filter can also remove resonance frequency components as well
as anti-resonance frequency components, enhancing the effect of a conventional damp-
ing filter to generate smooth torque commands and offering a better damping effect.
In addition, the removal of anti-resonance frequency components and resonance fre-
quency components can increase the responsiveness of the command response filter,
which improves the settling time.
However, unlike a conventional damping filter, the model-type damping filter cannot
obtain vibration components from the position sensor for the measurement of anti-
resonance frequency components and resonance frequency components, which thus
requires frequency characteristics analysis and the setting of optimum parameter values.
Applicable Range
This function can only be applicable when the following conditions are satisfied.
Conditions under which the Model type resonance oppression notch
filter is activated
Control mode
• Control mode to be Two-degree-of-freedom control position control.
Caution
This function does not work properly or no effect is obtained under the following condi-
tions.
Conditions which obstruct the Model type resonance oppression notch
filter effect
Load
condition
•
Vibration is triggered by other factors than command (such as disturbance).
• Resonance frequency and antiresonance frequency is out of the range of
5.0-300.0 [Hz].
