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 "Automatic setting (_ _ 1 _)"
in [Pr. PB02], this parameter will be set automatically. Set this parameter manually when
"Manual setting (_ _ 2 _)" is selected.

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 "Automatic setting (_ _ 1 _)"
in [Pr. PB02], this parameter will be set automatically. Set this parameter manually for "Manual
setting (_ _ 2 _)".
