PB17 Shaft resonance suppression filter
Set the shaft resonance suppression filter.
This is used to suppress a low-frequency machine
vibration.
When "Shaft resonance suppression filter selection"
is "Automatic setting (_ _ _ 0)" in [Pr. PB23], the
value will be calculated automatically from the servo
motor you use and load to motor inertia ratio. Set
manually for "Manual setting (_ _ _ 1)".
When "Shaft resonance suppression filter selection"
is "Disabled (_ _ _ 2)" in [Pr. PB23], the setting
value of this parameter is disabled.
When "Machine resonance suppression filter 4
selection" is "Enabled (_ _ _ 1)" in [Pr. PB49], the
shaft resonance suppression filter is not available.
