The process of automatically searching for the vibration frequency is shown in the following

Note:
1. When the values of P1.026 and P1.028 are both 0, it means that the frequency cannot be found,
probably because the detection level 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 and the vibration is not reduced, it is probably
because the detection level is set too low, and the system detects noise or other frequency as
low-frequency vibration.
3. When the auto suppression procedure completes, but the vibration persists, you can manually set
P1.025 or P1.027 to suppress the vibration if you have identified the low frequency.
Refer to Chapter 8 for detailed descriptions of the relevant parameters.
Parameter
P1.029
P1.030
P1.030 sets the detection range for the peak-to-peak amplitude of low-frequency vibration.
When the frequency is not detected, it is probably because the value of P1.030 is set too high
and it exceeds the vibration range. If so, it is suggested that you decrease the value of P1.030.
Note that if the value is set too small, the system might detect noise as the low-frequency
vibration. In this case, you can use the Scope function of ASDA-Soft and set the channel to
