There are two sets of low-frequency vibration suppression parameters: one is parameters
P1.025 - P1.026 and the other is parameters P1.027 - P1.028. You can use these two sets of
parameters to reduce two different low-frequency vibrations. Use P1.025 and P1.027 to set the
frequencies when the low-frequency vibrations occur. The suppression function works only
when the set frequency is close to the real vibration frequency. Use P1.026 and P1.028 to set
the response after frequency filtering. The greater the values of P1.026 and P1.028, the better
the response. However, if you set the values too high, the motor might not operate smoothly.
The default values of P1.026 and P1.028 are 0, which means the two filters are disabled by
default.
Refer to Chapter 8 for detailed descriptions of the relevant parameters.
