Parameter Speed control by real sensorless vector control, vector control
FR-A700 EC 6 - 109
6.3.7 Notch filter (Pr. 862, Pr. 863)
You can reduce the response level of speed control in the resonance frequency band of the
mechanical system to avoid mechanical resonance.
Notch filter time constant (Pr. 862)
●
If you do not know the mechanical resonance frequency, decrease notch frequency gradually
from the highest value. The point at which the smallest vibration is generated is the notch
frequency setting.
●
Machine characteristic can be obtained beforehand with machine analyzer by FR-Configu-
rator. Necessary notch frequency can be determined from this.
