Select the low-pass filter/adaptive vibration suppression
control.
0
Low-pass filter selection
0: Available (Automatic adjustment)
1: Disabled
When available is selected, the filter in
the zone expressed by the following
formula is automatically set.
For 1 kW or less
VG2 setting value × 10
2π × (1 + GD2 setting value × 0.1)
For 2 kW or less
2π × (1 + GD2 setting value × 0.1)
Adaptive vibration suppression control
selection
If "available" or "maintained" is
selected in the adaptive vibration
suppression control selection,
machine resonance control filter 1
([Pr. 58]) will become ineffective.
0: Disabled
1: Enabled
Usually, machine resonance
frequency is detected, and a filter
corresponding to the resonance
is generated to control the
machine vibration.
2: Maintenance
Until then, detection of machine
resonance is stopped by keeping
the characteristics of the filter
generated until that moment.
Adaptive vibration suppression control
selection
Select Adaptive vibration suppression
control.
0: Normal
1: High sensitive
61 Load to motor inertia ratio 2
Used to set the load to motor inertia ratio when gain
switching is enabled.

One of the following statuses is applied, depending
on how [Pr. PB23] is set.
PB23

70 PB29 Gain switching load to motor inertia ratio
Used to set the load to motor inertia ratio when gain
switching is enabled.
This parameter is enabled only when "Manual mode
(_ _ _ 3)" is selected in "Gain adjustment mode
selection" of [Pr. PA08].
Setting range: 0.00 to 300.00; Unit: x 1.0
Note that the setting unit is different from that for
MR-J2S-_A_.
When setting a value, set a value 0.1 x the
MR-J2S-_A_ setting value.
