Low-Frequency Vibration Suppression In Position Mode - Delta ASD-A2-0121 Series User Manual

Chapter 6 Control Mode of Operation ASDA-A2

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 1.0 Hz
and 100.0 Hz. Both manual setting and auto setting are provided.
Auto setting:
If it is difficult to find the frequency, enable the function of auto low-frequency vibration suppression
to automatically search 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 start 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 the low-
frequency vibration still exists, please check if the function of P1-26 or P1-28 is enabled. If the
values of P1-26 and P1-28 are both 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
vibration.
