Chapter 5 Trial Operation and Tuning
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
P2-43 and P2-44 as well as 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.
