DescriptionName / Range /
Selection
No.
Not selected / uint32Determines (or selects a source that determines)
whether the output of the oscillation damping function
is applied to the torque reference or not.
Note: Before enabling the oscillation damping output,
adjust parameters 26.53…26.57. Then monitor the input
signal (selected by 26.53) and the output (26.58) to
make sure that the correction is safe to apply.

Speed error / uint32Selects the input signal for the oscillation damping
function.
Note: Before changing this parameter run-time, disable
the oscillation damping output using parameter 26.52.
Monitor the behavior of 26.58 before re-enabling the
output.

31.0 Hz / real32Defines the center frequency of the oscillation damping
filter.
Set the value according to the number of oscillation
peaks in the monitored signal (selected by 26.53) per
second.
Note: Before changing this parameter run-time, disable
the oscillation damping output using parameter 26.52.
