ABB ACS880-104

266 Parameters
24.16 Frequency of pole Defines the frequency of pole of the resonance frequency
filter.
Note: If this value is very different from the value of 24.14, the
frequencies near the frequency of pole are amplified, which
can damage the driven machine.
40.00 Hz
0.50 … 500.00 Hz Frequency of pole. 1 = 1 Hz
24.17 Damping of pole Defines the damping coefficient for parameter 24.16. The
coefficient shapes the frequency response of the resonance
frequency filter. A narrower bandwidth results in better
dynamic properties. By setting this parameter to 1, the effect
of the pole is eliminated.
Note: To ensure that the resonance frequency band is filtered
(rather than amplified), the value of 24.15 must be smaller
than 24.17.
