Chapter 5 Trial operation and Tuning
The procedure of the auto resonance suppression is as the followings:
Motor alternately
Note:
1. Parameters P2-44 and P2-46 are the setting values of resonance suppression. If you have set to the
maximum (32dB) and cannot suppress the resonance, please reduce the speed bandwidth. After setting
P2-47, you can check the values of P2-44 and P2-46. If the value of P2-44 is not 0, it means there is a
resonance frequency in the system. Then, you 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 occurs, after you set P2-47 to 1 for 3 times, please manually adjust the setting of
resonance.
