No. Name and function
PB17 Automatic setting parameter
The value of this parameter is set according to a set
value of [Pr. PB06] (Load to motor inertia moment ratio).
PB18 Low-pass filter setting
Set the low-pass filter.
Setting [Pr. PB023] (low-pass filter selection) to "_ _ 0 _"
automatically changes this parameter.
When [Pr. PB023] is set to "_ _ 1 _" , this parameter can
be set manually.
PB19 Vibration suppression control vibration frequency setting
This parameter cannot be used in the speed control
mode.
Set the vibration frequency for vibration suppression
control to suppress low-frequency machine vibration,
such as enclosure vibration.
When [Pr. PB02] is set to "_ _ _ 2" , this parameter can
be set manually.

value
PB17 Shaft resonance suppression filter
Set a shaft resonance suppression filter.
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. When
"Manual setting (_ _ _ 1)" is selected, the setting written
to the parameter is used.
When "Shaft resonance suppression filter selection" is
"Disabled (_ _ _ 2)" in [Pr. PB23], the setting value of
this parameter will be disabled.
When you select "Enabled (_ _ _ 1)" of "Machine
resonance suppression filter 4 selection" in [Pr. PB49],
the shaft resonance suppression filter is not available.

100.0 PB19 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. When
"Manual setting (_ _ _ 2)" is selected, the setting written
to the parameter is used.
