How can running frequencies be skipped in an ATV61/ATV71 ?
Issue:
Skipping output frequencies in an ATV61/ATV71
Resolution:
The Skip Frequency function allows an ATV61 or ATV71 drive to avoid operating at specific motor speeds that may cause resonance, vibration, or excessive noise.
To configure a skip frequency, navigate to Menu 1.3 - Settings and adjust the following parameters:
- Skip Frequency (JPF): Sets the center frequency of the range to be skipped.
- Skip Frequency Hysteresis (JFH): Defines how many hertz (Hz) above and below the center frequency will be excluded.
The skipped frequency range is calculated as:
(JPF - JFH) to (JPF + JFH)
Note: The JFH hysteresis applies to all three skip frequency parameters: JPF, JF2, and JF3.
Example
- JPF = 30 Hz
- JFH = 2 Hz
The drive will avoid operating between 28 Hz and 32 Hz:
- Lower limit: 30 - 2 = 28 Hz
- Upper limit: 30 + 2 = 32 Hz
This setting helps prevent operation within frequency ranges that can create unwanted motor resonance, vibration, or noise.
