Lowpass output
Use:
The electronic unit provides a lowpass filter to prevent noise which is
added to the feedback signal, caused by unbalanced rollers or
interference. This parameter stores the limit frequency. The filtered
feedback value will be fed to the PI controller.
The lowpass output filter is independent of the other filters.
Notice:
The lower the cut-off frequency, the more sluggish the output
signal will be. If the limit frequency is set too low, the control
dynamics may be reduced dramatically!
Range:

200.0
Default:
50.0
Increment:

Lowpass instrument
Use:
The electronic unit provides a lowpass filter to prevent noise which is
added to the analog output of the instrument (terminals z18 / z22 resp.
15 / 18). This parameter stores the limit frequency. The lower the cut-
off frequency, the more sluggish the output signal will be. Due to this
filter, the display on the instrument will be much more stable in the
case of high fluctuations of the force value.
The lowpass instrument filter is independent of the other filters.
Range:
0.1
to
10.0
Default:
1.0
Increment:
0.1
Unit:
[Hz]
Lowpass display
Use:
The electronic unit provides a lowpass filter to prevent noise which is
added to the integrated display. This parameter stores the limit frequency.
The lower the cut-off frequency, the more sluggish the output signal
will be. Due to this filter, the value shown in the integrated display will
be much more stable in the case of high fluctuations of the force value.
The lowpass display filter is independent of the other filters.
Range:
0.1
to
10.0
Default:
1.0
Increment:
0.1
Unit:
[Hz]
Scale instrument
Use:
The analog output for the external instrument (0...10V) provides the
nominal voltage when reaching the nominal force value. Using a
setting of 1.00, the nominal voltage will be 10V. The nominal voltage
is decreased when decreasing the setting value; it is increased when
increasing the setting value.
Range:
0.01
to
10.00
Default:
1.00
