ASDA-A2  Chapter 5  Trial operation and Tuning 
Revision February, 2017                                                                      5-17 
 
 
NOTE
 
1.  Parameter P2-44 and P2-46 are the setting value of resonance suppression. If the value has been set 
to the maximum (32dB), and still cannot suppress the resonance, please reduce the speed bandwidth. 
After setting P2-47, users can check the value of P2-44 and P2-46. If the value of P2-44 is not 0, it 
means the resonance frequency exists in the system. Then, users can access P2-43 to see the 
resonance frequency (Hz). When there is another resonance frequency, the information will be shown in 
P2-45 and p2-46.  
2.  If resonance still exists, repeatedly set P2-47 to 1 for 3 times and manually adjust the setting of 
resonance.
