Chapter 5 Trial Run and Tuning Procedure
NOTE
1) Parameters P2-44 and P2-46 are used to set notch filter attenuation rate. If the resonance can
not be suppressed when the setting values of P2-44 and P2-46 are set to 32bB (the maximum
value), please decrease the speed loop frequency response. After setting P2-47, the users can
check the setting values of P2-44 and P2-46. If the setting value of P2-44 is not 0, it indicates
that one resonance frequency exists in the system and then the users can read P2-43, i.e. the
frequency (unit is Hz) of the resonance point. When there is any resonance point in the system,
its information will be shown in P2-45 and P2-46 as P2-43 and P2-44.
2) If the resonance conditions are not improved when P2-47 is set to 1 for over three times,
please adjust notch filters (resonance suppression parameters) manually to or eliminate the
resonance.
