    How can frequencies be skipped in an ATV61 / ATV71 ?

    Product Line:
    Altivar ATV61 and ATV71


    Motor is making a noise when running at a certain speed range.

    In menu 1.3 Settings, adjust the following parameters:
    Skip Freq = desired frequency  ( in the middle of the skip range )
    Skip Freq Hysteresis = (+) and (-) frequencies to be skipped

    Example :
    Skip Freq = 30Hz
    Skip Freq Hysteresis = 2
    The skipped range will include 2Hz below and 2Hz above the 30Hz Skip Freq.
    The total skipped range is 28Hz - 32Hz.
