Chapter 6  Control Mode of Operation  ASDA-A2 
6-20     Revision February, 2017 
Note 1: When the value of P1-26 and P1-28 is 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 still cannot eliminate the vibration, it 
is probably because the detection level is set too low, 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 is identified.

1: The value will set back to 0 after vibration suppression. 
Description of Auto Mode Setting: 
When the parameter is set to 1, it is in auto suppression. When the 
vibration frequency is not being detected  or the value of searched 
frequency is stable, the parameter will set to 0 and save the low-
frequency vibration suppression to P1-25 automatically.
