This parameter is used to set low-pass filter time constant of resonance suppression.
If P2-25 is set to 0, this parameter is disabled.
There are two groups of notch filters provided by ASDA-A2 series. The first group of notch filter is
P2-43 and P2-44, and the second group of notch filter is P2-45 and P2-46. When there is
resonance, please set P2-47 to 1 or 2 (Auto mode), and then the servo drive will find resonance
frequency and suppress the resonance automatically. After suppressing the resonance point, the
system will memorize the notch filter frequency into P2-43 and P-45, and memorize the notch filter
attenuation rate into P2-44 and P2-46.
When P2-47 is set to 1, the resonance suppression will be enabled automatically. After the
mechanical system becomes stable (approximate 20 minutes), the setting value of P2-47 will
return to 0 (Disable auto resonance suppression function). When P2-47 is set to 2, the system will
find the resonance point continuously even after the mechanical system becomes stable.
When P2-47 is set to 1 or 2, if the resonance conditions can not be eliminated, we recommend the
users to check the settings of P2-44 and P2-46. If either of the setting value of P2-44 and P2-46 is
set to 32, please decrease the speed frequency response and estimate the resonance point again.
If the resonance conditions can not be eliminated when the setting values of P2-44 and P2-46 are
both less than 32, please set P2-47 to 0 first, and increase the setting value of P2-44 and P2-46
manually. If the resonance exists still after increasing the setting value of P2-44 and P2-46, please
decrease the value of speed frequency response again and then use the resonance suppression
function again.
