Set forms of the machine resonance suppression filter 2.

_ _ _ x Machine resonance suppression filter 2 selection

_ _ x _ Notch depth selection

_ x _ _ Notch width selection

x _ _ _ For manufacturer setting

Set the shaft resonance suppression filter.

Use this to suppress a low-frequency machine vibration.

When you select "Automatic setting (_ _ _ 0)" of "Shaft resonance suppression filter selection" in [Pr.

PB23], the value will be calculated automatically from the servo motor you use and load to motor inertia

ratio. It will not be automatically calculated for the linear servo motor. When "Manual setting (_ _ _ 1)" is

selected, the setting written to the parameter is used as it is.

When "Shaft resonance suppression filter selection" is set to "Disabled (_ _ _ 2)" in [Pr. PB23], the

setting value of this parameter will be disabled.

When "Machine resonance suppression filter 4 selection" is set to "Enabled (_ _ _ 1)" in [Pr. PB49], the

shaft resonance suppression filter is not available.

When "Shaft resonance suppression filter selection" is set to "Disabled (_ _ _ 2)" in [Pr. PB23], the

performance may be reduced.
