10.6 Resonance suppression
Resonance suppression with real-time auto tuning (p29021=3, p29024.6=1)
When you choose to use the resonance suppression function with real-time auto tuning, the
servo drive performs real-time detection of the resonance frequency and configures the
following notch filter relevant parameters accordingly:
Parameter Value range
p1663 0.5 to 16000
p1664 0.001 to 10
p1665 0.5 to 16000
p1666 0.0 to 10
Resonance suppression with manual tuning (p29021=0)
When both the resonance suppression with real-time auto tuning and one-button tuning
mode cannot reach the suppression effect, you can do the resonance suppression by
manually setting the following parameters:
Parameter Value range
p1663 0.5 to 16000
p1664 0.001 to 10
p1665 0.5 to 16000
p1666 0.0 to 10
p1668 0.5 to 16000
p1669 0.001 to 10
p1670 0.5 to 16000
p1671 0.0 to 10
p1673 0.5 to 16000
p1674 0.001 to 10
p1675 0.5 to 16000
p1676 0.0 to 10
Assume the notch frequency is f
parameters can be calculated as follows:
p1663=p1665=f
p1664=f
p1666=(f
