ID210 (P2.025) ResonanceSuppressionLowPassFilterTime [NLP]
A high inertial value ratio reduces the frequency response of the speed loop.
Therefore, you must increase the KVP value to maintain the response frequency.
Increasing KVP value might cause machinery resonance. Use this parameter to
mitigate the noise from resonance. The higher the value, the better the capability
for reducing high-frequency noise. However, if you set the value too high, it can
cause instability in the speed loop and overshoot in positioning. It is suggested
that you set the value as follows:
ID211 (P2.026) AntiInterferenceGain [DST]
Use this parameter to increase the ability to resist external force and mitigate
overshoot during acceleration / deceleration. The default value is 0. Adjusting
this value in Manual mode is not suggested unless it is for fine-tuning.
ID187 (P2.002) VelocityFeedforwardGain [PFG]
This parameter can reduce the position error and shorten the settling time.
However, if you set the value too high, it might cause overshoot in positioning. If
the setting of the e-gear ratio is larger than 10, it might cause noise as well.
