(2)Parameters
The operation of adaptive vibration suppression control selection (parameter No.25).
Parameter No. 25
0 0
Adaptive vibration suppression control selection
0:Invalid
1:Valid
Machine resonance frequency is always detected to generate the filter in response to resonance, suppressing machine vibration.
2:Held
Filter characteristics generated so far is held, and detection of machine resonance is stopped.
Adaptive vibration suppression control sensitivity selection
Set the sensitivity of detecting machine resonance.
0:Normal
1:Large sensitivity
POINT
Adaptive vibration suppression control is
The filter characteristics generated are saved in the motion controller every 10s since
Selection the adaptive vibration suppression control sensitivity can change the sensitivity of detecting machine resonance. Selection of "large sensitivity" detects smaller machine resonance and generates a filter to suppress machine vibration. However, since a phase delay will also increase, the response of the servo system may not increase.
7.4 Low-pass filter
(1)Function
When a ballscrew or the like is used, resonance of high frequency may occur as the response of the servo system is increased. To prevent this, the
