value Unit Setting
range
PB18 LPF Low-pass filter setting
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.
3141 rad/s 100

18000
PB19 VRF1 Vibration suppression control vibration frequency setting
This parameter cannot be used in the speed control mode.
Set the vibration frequency for vibration suppression control to suppress low-frequency
machine vibration, such as enclosure vibration. (Refer to section 7.4.(4))
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.
100.0 Hz 0.1
to
100.0
PB20 VRF2 Vibration suppression control resonance frequency setting
This parameter cannot be used in the speed control mode.
Set the resonance frequency for vibration suppression control to suppress low-
frequency machine vibration, such as enclosure vibration. (Refer to section 7.4.(4))
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.

PB24 *MVS Slight vibration suppression control selection
Select the slight vibration suppression control and PI-PID change.
When parameter No.PA08 (auto tuning mode) is set to " 3", this parameter is
made valid. (Slight vibration suppression control cannot be used in the speed control
mode.)
