Figure 5-6 Procedure of auto suppressing the resonance

Note:

1. Resonance suppression is determined by parameter P2-44 and P2-46. If the value has been set to the

maximum (32 dB), 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 more than 3 times and manually adjust the setting of

resonance.
