Low-pass filter, Notch Filter | Delta Electronics ASDA-AB guide

Chapter 6 Control Modes of OperationASDA-AB Series

Low-pass filter

Please use parameter P2-25. The figure below shows the resonant open-loop gain. Gain

Frequency

When the low-pass filter (parameter P2-25) is adjusted from 0 to high value, the value of Low-pass frequency (BW) will become smaller (see the figure below). The resonant condition is improved and the frequency response and phase margin will also decrease.

BW

Notch Filter

Usually, if the users know the resonance frequency, we recommend the users can eliminate the resonance conditions directly by using notch filter (parameter P2-23, P2-24). However, the range of frequency setting is from 50 to 1000Hz only and the range of resonant attenuation is 0~32 dB only. Therefore, if the resonant frequency is out of this range, we recommend the users to use low-pass filter (parameter P2-25) to improve resonant condition.

Please refer to the following figures and explanation to know how to use notch filter and low-pass filter to improve resonant condition.
