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.

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.
