Description
Defines 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.
Monitor the behavior of
output.
Phase shift for oscillation damping function output.
Defines 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
output.
