Chapter 6 Control Mode of Operation ASDA-A2R Series
6-12 Revision December, 2014
6.2.9 Low-frequency Vibration Suppression in Position Mode
If the stiffness is not enough, the mechanical transmission will continue to vibrate even
when the motor stops after completing the positioning command. The function of
low-frequency vibration suppression can eliminate the vibration of mechanical
transmission. The range is between 1.0Hz and 100.0HZ. Both manual setting and auto
setting are provided.
Auto setting:
If the frequency is hard to find, it can enable the function of auto low-frequency vibration
suppression. This function automatically searches the frequency of low-frequency
vibration. If P1-29 is set to 1, the system will disable the function of low-frequency
vibration suppression automatically and starts to search the vibration frequency. When
the detected frequency remains at the same level, P1-29 will be set to 0 automatically
and set the first frequency in P1-25 and set P1-26 to 1. The second frequency will be set
in P1-27 and then set P1-28 to 1. If P1-29 is automatically set back to 0 and still has
low-frequency vibration, please check if the function of P1-26 or P1-28 is enabled. If the
value of P1-26 and P1-28 is 0, it means no frequency has been detected. Please
decrease the value of P1-30 and set P1-29 to 1 so as to search the vibration frequency
again. Please note that when the detection level is set too small, the noise will be
regarded as the low-frequency.
