MR-J3-_A_
No. Name and function
PB18 Low-pass filter setting
Set the low-pass filter.
Setting [Pr. PB23] (low-pass filter selection) to "_ _
0 _" automatically changes this parameter.
When [Pr. PB23] is set to "_ _ 1 _ ", this parameter
can be set manually.
PB19 Vibration suppression control vibration frequency
setting
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
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 [Pr. PB02] is set to "_ _ _ 2", this
parameter can be set manually.
PB21 For manufacturer setting
Do not change this value by any means.

No.
value
3141 PB18
Same as MR-J3
Low-pass filter setting
Set the low-pass filter.
The following shows a relation of a required
parameter to this parameter.
[Pr. PB23]
_ _ 0_ (Initial value)
_ _ 1 _
_ _ 2 _
Setting is not necessary because this parameter is
automatically set.
100.0 PB19
Same as MR-J3
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)".
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. Refer to "MR-J4-_A_ Servo
amplifier instruction manual".
Setting range: 0.1 to 300.0
PB20 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)".
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. Refer to "MR-J4-_A_ Servo
amplifier instruction manual".
Setting range: 0.1 to 300.0
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)".
Refer to "MR-J4-_A_ Servo amplifier instruction
manual".
Setting range: 0.00 to 0.30
