Flowchart of auto low-frequency vibration suppression:
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.

Setting
P1-30 VCL Low-frequency Vibration Detection
P1-30 is to set the range to detect the magnitude of low-frequency vibration. When the
frequency is not being detected, it is probably because the value of P1-30 is set too big
which exceeds the range of vibration. It is suggested to decrease the value of P1-30.
Please note that if the value is too small, the system might regard the noise as the
vibration frequency. If the SCOPE is available, it can be used to observe the range of
position error (pulse) between upper and lower magnitude of the curve and set up the
appropriate value of P1-30.
