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