PB18 LPF
Low-pass filter setting [Applied]
Set the low-pass filter.
Setting parameter No. PB23 (low-pass filter selection) to " 0 "
automatically changes this parameter.
When parameter No. PB23 is set to " 1 ", this parameter can be
set manually.

PB19 VRF1 Vibration suppression control vibration frequency setting [Applied]
Set the vibration frequency for vibration suppression control to
suppress low-frequency machine vibration, such as enclosure
vibration.
Setting parameter No. PB02 (vibration suppression control tuning
mode) to " 1" automatically changes this parameter. When
parameter No. PB02 is set to " 2", this parameter can be set
manually.

PB20 VRF2 Vibration suppression control resonance frequency setting [Applied]
Set the resonance frequency for vibration suppression control to
suppress low-frequency machine vibration, such as enclosure
vibration.
Setting parameter No. PB02 (vibration suppression control tuning
mode) to " 1" automatically changes this parameter. When
parameter No. PB02 is set to " 2", this parameter can be set
manually.
