PB52 VRF21 Vibration suppression control 2 - Vibration frequency 
Set the vibration frequency for the vibration suppression control 2 to suppress low-frequency 
machine vibration. 
To enable this setting, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode 
selection" in [Pr. PA24]. 
When "Vibration suppression control 2 tuning mode selection" is set to "Automatic setting (_ _ 
1 _)" in [Pr. PB02], this parameter will be set automatically. When "Manual setting (_ _ 2 _)" is 
selected, the setting written to the parameter is used. 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 will be disabled. Refer to section 7.1.5 for details.

PB53 VRF22 Vibration suppression control 2 - Resonance frequency 
Set the resonance frequency for the vibration suppression control 2 to suppress low-frequency 
machine vibration. 
To enable this setting, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode 
selection" in [Pr. PA24]. 
When "Vibration suppression control 2 tuning mode selection" is set to "Automatic setting (_ _ 
1 _)" in [Pr. PB02], this parameter will be set automatically. When "Manual setting (_ _ 2 _)" is 
selected, the setting written to the parameter is used. The setting range of this parameter

PB54  VRF23  Vibration suppression control 2 - Vibration frequency damping 
Set a damping of the vibration frequency for the vibration suppression control 2 to suppress 
low-frequency machine vibration. 
To enable this setting, select "3 inertia mode (_ _ _ 1)" of "Vibration suppression mode 
selection" in [Pr. PA24]. 
When "Vibration suppression control 2 tuning mode selection" is set to "Automatic setting (_ _ 
1 _)" in [Pr. PB02], this parameter will be set automatically. When "Manual setting (_ _ 2 _)" is 
selected, the setting written to the parameter is used. Refer to section 7.1.5 for details.
