Note:
1. When the values of P1.026 and P1.028 are both 0, it means no frequency is detected. It is probably
because P1.030 (Low-frequency vibration detection) is set too high so that the low-frequency vibration
is not detected.
2. When the value of P1.026 or P1.028 is greater than 0, but the vibration persists, it is probably because
P1.030 is set too low, causing the system to mistakenly regard minor frequency or noise as the low-
frequency vibration.
Manual setting:
When the auto suppression procedure is complete, but the vibration persists, you can manually
set P1.025 or P1.027 to suppress the vibration if you have identified the vibration frequency.
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 for low-frequency vibration suppression. The filter function works only when the
parameter setting is close to the actual vibration frequency. Use P1.026 and P1.028 to set the
response after frequency filtering. The bigger 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.
