No. Name and function
PB19 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.
When [Pr. PB02] is set to "_ _ _ 2", this parameter can
be set manually.
PB20 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.
When [Pr. PB02] is set to "_ _ _ 2", this parameter can
be set manually.
PB21 This parameter is not used. Do not change the value.
PB22 This parameter is not used. Do not change the value.

value
100.0 PB19 Vibration suppression control 1 - Vibration frequency
Set the vibration frequency for vibration suppression
control 1 to suppress low-frequency machine vibration.
When "Vibration suppression control 1 tuning mode
selection" is set to "Automatic setting (_ _ _ 1)" in [Pr.
PB02], this parameter will be set automatically. When
"Manual setting (_ _ _ 2)" is selected, the setting written
to the parameter is used.
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 will be disabled.
100.0 PB20 Vibration suppression control 1 - Resonance frequency
Set the resonance frequency for vibration suppression
control 1 to suppress low-frequency machine vibration.
When "Vibration suppression control 1 tuning mode
selection" is set to "Automatic setting (_ _ _ 1)" in [Pr.
PB02], this parameter will be set automatically. When
"Manual setting (_ _ _ 2)" is selected, the setting written
to the parameter is used.
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 will be disabled.
0.00 PB21 Vibration suppression control 1 - Vibration frequency
damping
Set a damping of the vibration frequency for vibration
suppression control 1 to suppress low-frequency
machine vibration.
When "Vibration suppression control 1 tuning mode
selection" is set to "Automatic setting (_ _ _ 1)" in [Pr.
PB02], this parameter will be set automatically. When
"Manual setting (_ _ _ 2)" is selected, the setting written
to the parameter is used.
0.00 PB22 Vibration suppression control 1 - Resonance frequency
damping
Set a damping of the resonance frequency for vibration
suppression control 1 to suppress low-frequency
machine vibration.
When "Vibration suppression control 1 tuning mode
selection" is set to "Automatic setting (_ _ _ 1)" in [Pr.
PB02], this parameter will be set automatically. When
"Manual setting (_ _ _ 2)" is selected, the setting written
to the parameter is used.
