180 deg / real32 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 26.58 before re-enabling the
output.
Oscillation damping
phase 26.56
10 = 1 deg / 1 = 1 deg Phase shift for oscillation damping function output. 0...360 deg
1.0 % / real32 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 26.58 before re-enabling the
output.
Oscillation damping
gain 26.57
10 = 1 % / 10 = 1 % Gain setting for oscillation damping output. 0.0 ... 100.0 %
- / real32 Displays the output of the oscillation damping function.
This value is added to the torque reference (as allowed
by parameter
26.52 Oscillation damping out enable ).
This parameter is read-only.

10 = 1 % / 1000 = 1 % Output of the oscillation damping function. -1600.000 ...
1600.000 %
- / real32 Displays the value of torque reference source 1
(selected by parameter
26.11 Torque ref1 source ). See
the control chain diagram on page 751 .
This parameter is read-only.

(selected by parameter
26.12 Torque ref2 source ). See
the control chain diagram on page 751 .
This parameter is read-only.

- / real32 Displays the torque reference after the function applied
by parameter
26.13 Torque ref1 function (if any), and
after selection ( 26.14 Torque ref1/2 selection ). See the
control chain diagram on page 751 .
This parameter is read-only.

- / - Torque reference after selection. For scaling, see
parameter
46.3 .
-1600.0 ... 1600.0 %
- / real32 Displays the torque reference after application of
reference additive 1. See the control chain diagram on
page
