284 Parameters
26.55 Oscillation damping
frequency
Defines 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.
31.0 Hz
0.1 … 60.0 Hz Center frequency for oscillation damping. 10 = 1 Hz
26.56 Oscillation damping
phase
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.
180 deg
0…360 deg Phase shift for oscillation damping function output. 10 = 1 deg
26.57 Oscillation damping
gain
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.
1.0%
0.0 … 100.0% Gain setting for oscillation damping output. 10 = 1%
26.58 Oscillation damping
output
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.
-
-1600.000 …
1600.000%
Output of the oscillation damping function. 10 = 1%
26.70 Torque reference
act 1
Displays the value of torque reference source 1 (selected by
parameter 26.11 Torque ref1 source). See the control chain
diagram on page 651.
This parameter is read-only.
-
-1600.0 … 1600.0% Value of torque reference source 1. See par.
46.03
26.71 Torque reference
act 2
Displays the value of torque reference source 2 (selected by
parameter 26.12 Torque ref2 source). See the control chain
diagram on page 651.
This parameter is read-only.
-
-1600.0 … 1600.0% Value of torque reference source 2. See par.
46.03
26.72 Torque reference
act 3
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 651.
This parameter is read-only.
-
-1600.0 … 1600.0% Torque reference after selection. See par.
46.03
26.73 Torque reference
act 4
Displays the torque reference after application of reference
additive 1. See the control chain diagram on page 651.
This parameter is read-only.
-
-1600.0 … 1600.0% Torque reference after application of reference additive 1. See par.
