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.
Setting [Pr. PB02] (vibration suppression control tuning
mode) to "_ _ _ 1"automatically changes this parameter.
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.
Setting [Pr. 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.
PB21 For manufacturer setting
Do not change this value by any means.
PB22 For manufacturer setting
Do not change this value by any means.
PB23 Low-pass filter selection
Select the low-pass filter.

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. Set
manually for "Manual setting (_ _ _ 2)".
100.0 PB20
Same as MR-J3
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. Set
manually for "Manual setting (_ _ _ 2)".
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. Set
manually for "Manual setting (_ _ _ 2)".
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. Set
manually for "Manual setting (_ _ _ 2)".
