frequency has been detected. Please decrease the value of P1-30 and set P1-29 to 1 so as to
search for the vibration frequency again. Please note that when the detection level is set to be
too small, the noise may be regarded as the frequency of low-frequency vibration.

Figure 6-4 Procedure of Auto Low-frequency Vibration Suppression
Note:
1. When the value of P1-26 and P1-28 are both 0, it means it is unable to search for the frequency. It is
probably because the detection level is set to be too high and is unable to detect the frequency of
low-frequency vibration.
2. When the value of P1-26 or P1-28 is not 0 and the vibration still cannot be diminished, it is probably
because the detection level is set to be too low, the system regards the noise or other non-primary
frequency as the frequency of low-frequency vibration.
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 of the low-frequency
vibration is identified.
