Instantaneous
Speed Observer
Setting (RT)
The Instantaneous Speed Observer improves speed de-
tection accuracy, thereby improving responsiveness and
reducing vibration when stopping.
When the instantaneous speed observer is enabled, both
Speed Feedback Filter Time Constant (Pn013) and Speed
Feedback Filter Time Constant 2 (Pn01B) are disabled.
This feature cannot be used with realtime autotuning.
For details, refer to 5-24 Instantaneous Speed Observer
on page 5-48.

Notch Filter 2
Frequency
Sets the notch frequency of notch filter 2 for resonance
suppression.
This parameter must be matched with the resonance
frequency of the load.

Notch Filter 2
Width
Selects the notch width of notch filter 2 for resonance
suppression.
Increasing the value increases the notch width.

02A
Notch Filter 2
Depth
Selects the notch depth of notch filter 2 for resonance
suppression.
Increasing this value decreases the notch depth, thereby
reducing the phase lag.
0 --- 0 to 99 B
02B
Vibration
Frequency 1
Sets the vibration frequency 1 for damping control to
suppress vibration at the end of the load.
Measure and set the frequency of the vibration.
The frequency setting range depends on the filter type
selected in the Vibration Filter Selection (Pn024).
 Normal type
Setting frequency range: 10.0 to 200.0 Hz (Disabled
when set to 0 to 99)
 Low-pass type
Setting frequency range: 1.0 to 200.0 Hz (Disabled when
set to 0 to 9)
For details, refer to 5-25 Damping Control on page 5-50.

Vibration Filter 1
Setting
When setting Vibration Frequency 1 (Pn02B), reduce this
setting if torque saturation occurs, or increase it to make
the movement faster.
Normally, use a setting of 0.
The setting range depends on the filter type selected in the
Vibration Filter Selection (Pn024), and if Vibration Filter 1
is enabled, the ranges are as follows:
Note This parameter is disabled when Vibration Filter 1
is disabled.
