Issue:
Skip Frequency to eliminate mechanical vibration
Product Line:
ATV61 and ATV71
Environment:
All models and serial numbers
Cause:
None
Resolution:
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).
