Modes of Operation
Chapter 10
Automatic Setting
If you have difficulty in finding out the frequency of resonance, you can enable
the function of auto low-frequency vibration suppression, which searches the
specific frequency of resonance occurrence. If parameter Low-frequency
Vibration Suppression Mode Setting ID139 (P1.029) is set to 1, the system will
disable this function automatically and starts to search the vibration frequency.
When the detected frequency remains at the same level, ID139 (P1.029) is set to
0 automatically and set the first frequency in parameter ID135 (P1.025) and set
parameter ID136 (P1.026) to 1. The second frequency will be set in parameter
ID137 (P1.027) and then set parameter ID138 (P1.028) to 1. If parameter
ID139 (P1.029) is automatically reset to 0, but low-frequency vibration persists,
check if the function of parameter ID136 (P1.026) or ID138 (P1.028) is
enabled. If the values of parameters ID136 (P1.026) and ID138 (P1.028) are
both 0, it means no frequency has been detected. Lower the value of parameter
ID140 (P1.030) and set parameter ID139 (P1.029) to 1 so as to search the
vibration frequency again.
Auto Low-frequency Vibration Suppression
IMPORTANT
When the detection level is set too small, noise might be regarded as low-
frequency vibration.

(1) When the auto suppression procedure completes but the vibration persists, you can manually set
ID135 (P1.025) or ID137 (P1.027) to suppress the vibration if you have iden
tified the lo
w frequency.
(2) When the values of P1.026 and P1.028 are 0, it means that the frequency cannot be found, probably
because the detection level is set too high so that the low-frequency vibration is not detected.
(3) When the values of P1.026 or P1.028 are greater than 0 and the vibration is not reduced, it is probably
because the detection level is set too low, and the system detects noise or other frequency as
low-frequency vibration.
