ASDA-A2
Note 1: When the values of P1-26 and P1-28 are both 0, it means it is unable to search the frequency.
It is probably because the detection level is set too high and is unable to detect the low-frequency
vibration.
Note 2: When the value of P1-26 or P1-28 is not set to 0 and the vibration still cannot be reduced, it is
probably because the detection level is set too low, and the system regards the noise or other non-
primary frequency as the low-frequency vibration.
Note 3: When the process of auto vibration suppression is completed and the vibration still cannot be
diminished, P1-25 or P1-27 can be manually set to suppress the vibration if the frequency (Hz) of the
low-frequency vibration is identified.

value resets to 0 automatically.
Description of Auto Mode Setting:
When the value is 1, vibration suppression is in automatic mode. When
the vibration cannot be detected or the vibration frequency is stable,
the system resets the parameter to 0 and automatically saves the
vibration suppression frequency to P1-25.
