24
24 Speed reference
conditioning
Speed error calculation; speed error window control
configuration; speed error step.
See the control chain diagrams on pages
Displays the ramped and corrected speed reference (before
speed error calculation). See the control chain diagram on
page
This parameter is read-only.
-
-30000.00…
30000.00 rpm
Speed reference used for speed error calculation.
See par.
Displays the speed feedback used for speed error calculation.
See the control chain diagram on page
.
This parameter is read-only.
-
-30000.00…
30000.00 rpm
Speed feedback used for speed error calculation.
See par.
Displays the filtered speed error. See the control chain
diagram on page
.
This parameter is read-only.
-
-30000.0…
30000.0 rpm
Filtered speed error.
See par.
Displays the inverted (unfiltered) speed error. See the control
chain diagram on page
.
This parameter is read-only.
-
-30000.0…
30000.0 rpm
Inverted speed error.
See par.
Defines a speed reference correction, ie. a value added to the
existing reference between ramping and limitation. This is
useful to trim the speed if necessary, for example to adjust
draw between sections of a paper machine.
See the control chain diagram on page
.
0.00 rpm
-10000.00…
10000.00 rpm
Speed reference correction.
See par.
Defines the time constant of the speed error low-pass filter.
If the used speed reference changes rapidly, the possible
interferences in the speed measurement can be filtered with
the speed error filter. Reducing the ripple with this filter may
cause speed controller tuning problems. A long filter time
constant and fast acceleration time contradict one another. A
very long filter time results in unstable control.
0 ms
0…10000 ms
Speed error filtering time constant. 0 = filtering disabled.
1 = 1 ms
25
Speed controller settings.
See the control chain diagrams on pages
Torque reference
speed control
Displays the speed controller output that is transferred to the
torque controller. See the control chain diagram on page
.
This parameter is read-only.
-
-1600.0…1600.0%
Limited speed controller output torque.
See par.
No.
