Vibration
suppression control
2 - Vibration
frequency
Set the vibration frequency for vibration suppression control 2 to suppress low-frequency machine vibration.
When "Vibration suppression control 2 tuning mode selection" is set to "Automatic setting (_ _ 1 _)" in [Pr.
PB02], this parameter will be set automatically. "Manual setting (_ _ 2 _)" is selected, the setting written to the
parameter is used.
To enable the setting value, set "Vibration suppression mode selection" to "3 inertia mode (_ _ _ 1)" in [Pr.
PA24]. The setting range of this parameter varies, depending on the value in [Pr. PB07]. If a value out of the
range is set, the vibration suppression control is disabled.

frequency
Set the resonance frequency for vibration suppression control 2 to suppress low-frequency machine
vibration.
When "Vibration suppression control 2 tuning mode selection" is set to "Automatic setting (_ _ 1 _)" in [Pr.
PB02], this parameter will be set automatically. "Manual setting (_ _ 2 _)" is selected, the setting written to the
parameter is used.
To enable the setting value, set "Vibration suppression mode selection" to "3 inertia mode (_ _ _ 1)" in [Pr.
PA24]. The setting range of this parameter varies, depending on the value in [Pr. PB07]. If a value out of the
range is set, the vibration suppression control is disabled.

2 - Vibration
frequency after gain
switching
Set the vibration frequency for vibration suppression control 2 for when the gain switching is enabled.
When a value less than 0.1 Hz is set, the value will be the same as that of [Pr. PB52].
This parameter will be enabled only when the following conditions are fulfilled.
• "Gain adjustment mode selection" is set to "Manual mode (_ _ _ 3)" in [Pr. PA08].
• "Vibration suppression mode selection" is set to "3 inertia mode (_ _ _ 1)" in [Pr. PA24].
• "Vibration suppression control 2 tuning mode selection" is set to "Manual setting (_ _ 2 _)" in [Pr. PB02].
• "Gain switching selection" is set to "Switching is enabled by control command from controller and Input
device CDP (Gain switching) (_ _ _ 1)" in [Pr. PB26].
Switching during driving may cause a shock. Be sure to switch them after the servo motor stops.
