Skip Frequency to eliminate mechanical vibration
ATV61 and ATV71
All models and serial numbers
Skip frequency. This parameter prevents prolonged operation within an adjustable range around the regulated frequency. This function can be used to prevent a critical speed, which would cause resonance, being reached. Setting the function to 0 renders it inactive.
In the [SETTINGS] menu
Go to [Skip Freq.] and enter the frequency you want to skip.
If the resonance is within a range, you can use the [Skip.Freq.Hysteresis] parameter. This can be assigned from 0 to 10 hz. This makes the skip frequency range: between (JPF – JFH) and (JPF + JFH). This adjustment is common to all 3 frequencies (JPF, JF2 and JF3).
