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.
Manual Setting:
There are two sets of low-frequency vibration suppression filters. One is parameters P1-25 ~
P1-26 and the other is parameters P1-27 ~ P1-28. These two sets of filters can be used to
eliminate two different frequency vibrations. Parameters P1-25 and P1-27 are used to suppress
the low-frequency vibration. The function is working only when the parameter setting value of
low-frequency vibration is close to the real vibration frequency. Parameters P1-26 and P1-28 are
used to set the response after filtering. The bigger the setting value of P1-26 and P1-28 is, the
better response will be. However, if the value is set too big, the motor might not operate
smoothly. The default values of parameters P1-26 and P1-28 are 0, which means the function is
disabled. Followings are the related parameters:

search the detection level. The lower the value is, the more sensitive
the detection will be. However, it is easy to misjudge the noise or
regard the other low-frequency vibration as the suppression frequency.
If the value is bigger, it will make more precise judgment. However,
if the vibration of the mechanism is smaller, it might not detect the
frequency of low-frequency vibration.
