PB17 Set the shaft resonance suppression filter.
NHF Use this to suppress a high-frequency machine vibration.
Shaft resonance When you select "Automatic setting (_ _ _ 0)" of "Shaft resonance suppression filter selection" in [Pr. PB23], the value will be calculated
suppression filter 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.
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.

PB19  Set the vibration frequency for vibration suppression control 1 to suppress low-frequency machine vibration.
VRF11 When "Vibration suppression control 1 tuning mode selection" is set to "Automatic setting (_ _ _ 1)" in [Pr.
Vibration PB02], this parameter will be set automatically. When "Manual setting (_ _ _ 2)" is selected, the setting written
suppression control to the parameter is used. The setting range of this parameter varies, depending on the value in [Pr. PB07]. If
1 - Vibration a value out of the range is set, the vibration suppression control is disabled.
