Immediately Adjustment

Pn155 determines frequency at which Load Oscillation Suppression is to be performed.

Pn156 determines the filter time. You can increase this setting, and the filtering effect will be better.
However, it may reduce the suppression effect due to the lag.

You can set Limit for Load Oscillation Suppression (Pn157) as a proper limit value, helping to reduce
overshooting during the start and stop.
Frequency Detection for Load Oscillation Suppression
If the frequency for the Load Oscillation Suppression can be detected by a measuring instrument (laser
interferometer, etc.), please write the frequency data (in 0.1 Hz) into the Pn155 directly.
You can also use related functions in ESView V4 (FFT, etc.) to measure the frequency for the Load
Oscillation Suppression.
Application Restrictions
The following application restrictions apply to the Load Oscillation Suppression.

Load Oscillation Suppression can only be used when the Model Following Control is in effect.

Only applied for the Manual Tuning.

Only applied for the Position Control Modes.

It is unavailable in fully-closed loop control.
9.6.4 Automatic Vibration Suppression
The automatic vibration suppression function determines the vibration state by the Motor during
operation and recognizes the vibration frequency, and then selects the notch filter or the intermediate
frequency vibration suppression function according to the characteristics of the vibration and
automatically sets the vibration frequency.
The automatic vibration suppression function determines and detects the vibration frequency during the
operation of the Motor, and then choose the notch filter or the IF suppression function, and set the
relevant parameters for the vibration suppression.
Parameter Setting Meaning When Enabled Classification
Pn100.2
0 [Default]
Automatic Vibration Suppression is
disabled.
After restart Function
1
Automatic Vibration Suppression is
enabled.
Pn179
－
Amplitude Threshold for Vibration
Detection
Immediately Adjustment
Pn179 determines the threshold of a frequency amplitude. If the detected frequency amplitude exceeds
this setting, it will be regarded as a vibration.
