Defines the damping coefficient for parameter 24.14. The
value of 0 corresponds to the maximum elimination of the
resonance frequency.

Note: To ensure that the resonance frequency band is
filtered (rather than amplified), the value of 24.15 must be
smaller than 24.17.

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.
