• Do not set notch filter frequencies (Pn409, Pn40C, Pn417, Pn41A, and Pn41D) that are close
to the speed loop’s response frequency. Set a frequency that is at least four times the speed
loop gain (Pn100). (However, Pn103 (Moment of Inertia Ratio) must be set correctly. If the set-
ting is not correct, vibration may occur and the machine may be damaged.
• Change the notch filter frequencies (Pn409, Pn40C, Pn417, Pn41A, and Pn41D) only while the
Servomotor is stopped. Vibration may occur if a notch filter frequency is changed during oper-
ation.
