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.

1.11 DC voltage. (The value is internally filtered.)
DC voltage
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.
Monitor the behavior of 26.58 before re-enabling the output.

180 deg / real32Defines a phase shift for the output of the filter.
Note: Before changing this parameter run-time, disable
the oscillation damping output using parameter 26.52.

1.0 % / real32Defines a gain for the output of the oscillation damping
function, ie. how much the output of the filter is amplified
before it is added to the torque reference.
Oscillation gain is scaled according to the speed controller
gain so that changing the gain will not disturb oscillation
damping.
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.
