7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 7
7.1.4 Low-pass filter
(1) Function
When a ball screw or the like is used, resonance of high frequency may occur as the response level of
the servo system is increased. To prevent this, the low-pass filter is enabled for a torque command as
the initial value. The filter frequency of the low-pass filter is automatically adjusted to the value in the
following equation.
Filter frequency ([rad/s]) =
1 + GD2
VG2
× 10
To set [Pr. PB18] manually, select "Manual setting (_ _ 1 _)" of "Low-pass filter selection" in [Pr. PB23].
(2) Parameter
Set "Low-pass filter selection" in [Pr. PB23].
[Pr. PB23]

0: Automatic setting
1: Manual setting
2: Disabled

7.1.5 Advanced vibration suppression control II
POINT
The function is enabled when "Gain adjustment mode selection" in [Pr. PA08] is
"Auto tuning mode 2 (_ _ _ 2)", "Manual mode (_ _ _ 3)", or "2 gain adjustment
mode 2 (_ _ _ 4)".
The machine resonance frequency supported in the vibration suppression
control tuning mode is 1.0 Hz to 100.0 Hz. As for the vibration out of the range,
set manually.
Stop the servo motor before changing the vibration suppression control-related
parameters. Otherwise, it may cause an unexpected operation.
For positioning operation during execution of vibration suppression control
tuning, provide a stop time to ensure a stop after vibration damping.
Vibration suppression control tuning may not make normal estimation if the
residual vibration at the servo motor side is small.
Vibration suppression control tuning sets the optimum parameter with the
currently set control gains. When the response setting is increased, set vibration
suppression control tuning again.
When using the vibration suppression control 2, set "_ _ _ 1" in [Pr. PA24].
