24 Speed reference conditioning
Speed error calculation; speed error window control
configuration; speed error step.
See the control chain diagram on page
.
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
.
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
No.
