Parameters 211
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.
Note: For safety reasons, the correction is not applied
when an emergency stop is active.
WARNING! If the speed reference correction
exceeds
, a ramp stop may
be impossible. Make sure the correction is reduced
or removed when a ramp stop is required.
See the control chain diagram on page

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.
