PB56 Set the vibration frequency for vibration suppression control 2 for when the gain
switching is enabled.
VRF21B
When you set a value less than 0.1 Hz, the value will be the same as [Pr. PB52].
Vibration
suppression This parameter will be enabled only when the following conditions are fulfilled.
