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.
PB22 For manufacturer setting
Do not change this value by any means.
Initial
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)".
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)".
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)".
Setting range: 0.00 to 0.30
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)".
Setting range: 0.00 to 0.30
