When the vibration is suppressed but overshooting occurs, increase the Q value and check whether the over-
shooting is corrected.

1. Sufficient precautions must be taken when setting the notch frequencies. Do not set the notch frequen-
cies (Pn409 or Pn40B) that is close to the speed loop’s response frequency. Set the frequencies at least
four times higher than the speed loop’s response frequency. Setting the notch frequency too close to the
response frequency may cause vibration and damage the machine. The speed loop response frequency is
the value of the Speed Loop Gain (Pn100) when the Mass Ratio (Pn103) is set to the correct value.
2. Change the Notch Filter Frequency (Pn409 or Pn40B) only when the linear servomotor is stopped.
Vibration may occur if the notch filter frequency is changed when the linear servomotor is moving.
