PX04 VRF21 Vibration suppression control 2 - Vibration frequency
Set the vibration frequency for vibration suppression control 2 to suppress low-frequency
machine vibration.
To enable this, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode selection" in
[Pr. PX02].
When "Vibration suppression control 2 tuning mode selection" is "Automatic setting (_ _ 1 _)"
in [Pr. PX03], this parameter will be set automatically. Set manually for "Manual setting (_ _ 2
_)".

PX05 VRF22 Vibration suppression control 2 - Resonance frequency
Set the resonance frequency for vibration suppression control 2 to suppress low-frequency
machine vibration.
To enable this, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode selection" in
[Pr. PX02].
When "Vibration suppression control 2 tuning mode selection" is "Automatic setting (_ _ 1 _)"
in [Pr. PX03], this parameter will be set automatically. Set manually for "Manual setting (_ _ 2
_)".

PX06 VRF23 Vibration suppression control 2 - Vibration frequency damping
Set a damping of the vibration frequency for vibration suppression control 2 to suppress low-
frequency machine vibration.
To enable this, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode selection" in
[Pr. PX02].
When "Vibration suppression control 2 tuning mode selection" is "Automatic setting (_ _ 1 _)"
in [Pr. PX03], this parameter will be set automatically. Set manually for "Manual setting (_ _ 2
_)".

PX07 VRF24 Vibration suppression control 2 - Resonance frequency damping
Set a damping of the resonance frequency for vibration suppression control 2 to suppress low-
frequency machine vibration.
To enable this, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode selection" in
[Pr. PX02].
When "Vibration suppression control 2 tuning mode selection" is "Automatic setting (_ _ 1 _)"
in [Pr. PX03], this parameter will be set automatically. Set manually for "Manual setting (_ _ 2

PX08 VRF21B Vibration suppression control 2 - Vibration frequency after gain switching
Set the vibration frequency for vibration suppression control 2 when the gain switching is
enabled.
To enable this, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode selection" in
[Pr. PX02].
This parameter will be enabled only when the following conditions are fulfilled.
"Gain adjustment mode selection" in [Pr. PA08] is "Manual mode (_ _ _ 3)".
"Vibration suppression control 2 tuning mode selection" in [Pr. PX03] is "Manual setting (_ _
2 _)".
"Gain switching selection" in [Pr. PB26] is "Control command from controller is enabled (_ _
_ 1)".
When you set "0.0", the value will be the same as [Pr. PX04].
Switching during driving may cause a shock. Be sure to switch them after the servo motor or
linear servo motor stops.

PX09 VRF22B Vibration suppression control 2 - Resonance frequency after gain switching
Set the resonance frequency for vibration suppression control 2 when the gain switching is
enabled.
To enable this, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode selection" in
[Pr. PX02].
This parameter will be enabled only when the following conditions are fulfilled.
"Gain adjustment mode selection" in [Pr. PA08] is "Manual mode (_ _ _ 3)".
"Vibration suppression control 2 tuning mode selection" in [Pr. PX03] is "Manual setting (_ _

"Gain switching selection" in [Pr. PB26] is "Control command from controller is enabled (_ _
_ 1)".
When you set "0.0", the value will be the same as [Pr. PX05].
Switching during driving may cause a shock. Be sure to switch them after the servo motor or
linear servo motor stops.
