6.2.9 Low-frequency vibration suppression in Position mode
If the machine is too flexible, vibration persists even when the motor stops after executing the
Positioning command. The low-frequency vibration suppression function can reduce the
machine vibration. The suppression range is between 1.0 Hz and 100.0 HZ. Both auto and
manual functions are available.
Auto function
If you have difficulty finding the resonance frequency, you can enable the auto low-frequency
vibration suppression function, which searches for the specific resonance frequency. If you set
P1.029 to 1, the system disables this function automatically and starts to search the vibration
frequency. When the detected resonance frequency remains at the same level, it automatically
sets P1.029 to 0 and sets P1.025 to the first frequency and sets P1.026 to 1. It sets P1.027 to the
second frequency and then sets P1.028 to 1. If P1.029 is automatically reset to 0, but the
low-frequency vibration persists, please check that P1.026 or P1.028 is enabled. If the values of
P1.026 and P1.028 are both 0, it means no frequency is detected. Please lower the value of
P1.030 and set P1.029 to 1 to search the vibration frequency again. Please note that when you
set the detection level too low, it might detect noise as low-frequency vibration.
