Relevant Parameters of Auto Vibration Suppression (Please refer to Chapter 7 for detailed
description):
Parameter Abbr. Function
P1-29 AVSM Auto Low-frequency Vibration Suppression Setting
P1-30 VCL Low-frequency Vibration Detection
P1-30 is to set the range to detect the magnitude of low-frequency vibration. When the frequency
is not being detected, it is probably because the value of P1-30 is set to be too large which
exceeds the range of vibration. It is suggested to decrease the value of P1-30. Please note that if
the value is too small, the system might regard the noise as the vibration frequency. If the scope
is available, it can be used to observe the range of position error (pulse) between upper and
lower magnitude in order to set up the appropriate value of P1-30.
Manual Setting:
There are two sets of low-frequency vibration suppression. One is parameter P1-25 and P1-26
and the other one is parameter P1-27 and P1-28. These two sets of low-frequency vibration
suppression can be used to eliminate low-frequency vibration with two different frequencies.
Parameter P1-25 and P1-27 are used to set the frequency of low-frequency vibration. The
function is working only when the parameter setting value of low-frequency vibration suppression
is close to the real vibration frequency. Parameter P1-26 and P1-28 are used to set the response
after being processed by the filter. The bigger the setting value of P1-26 and P1-28 is, the better
the response will be. However, if the value is set to be too large, the motor might not operate
smoothly. The default value of parameter P1-26 and P1-28 are 0, which means the function is
disabled.
