P2-09/P2-10 skip frequency/skip frequency band

Setting range P2-09: P1-02 – P1-01

Setting range P2-10: 0.0 Hz – P1-01

In some applications, mechanical resonance vibrations may occur in certain speed ranges. This may have a negative effect on the machine behavior.

The speed skip function can be used to skip the interfering speed range. The input speed performs the hysteresis depicted in the figure with the ramps specified in P1-03 and P1-04.

If the setpoint speed is within the skipped frequency range, the actual speed remains on the upper or lower limit of the frequency range, depending on the previous setpoint.
