Chapter 6 Control Modes of Operation
Please note:
1. When P1-26 and P1-28 are both set to 0, it indicates that the system could not find
the frequency. Please check the setting value of P1-30 because when the setting value
of P1-30 is too high, it may causes that the frequency becomes difficult to be found.
2. When P1-26 and P1-28 are both set to a non-zero value, if the vibration condition can
not be improved, please check the setting value of P1-30 as the low setting value of
P1-30 may result in erroneous measurement. The system may regard the interference
as a low-frequency.
3. When the vibration still exists and can not be suppressed after using auto low-
frequency vibration suppression function, if the users know the vibration frequency,
please set P1-25 and P1-27 manually to improve the vibration condition.
