Description
Determines (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.
