7.4.3.4. Accuracy of the speed display
During operations the speed display usually fluctuates by a certain value. These fluctuations are
accounted for in the measuring priciple for the speed, since it is a scanning system.
In the menu point "
Exact
" you can limit these fluctuations
to a maximum value. It is a damping through a low pass
that results in a smoothing of the display, which means
that an averaging process is put into operation. The lower
the input value is, the quieter is the speed display. In
practice, you will always find a compromise between the
dynamics of the display and its readability.
Note:
The
"Exact"
value also corresponds to the speed value, which is provided by an CP16 or
CamCon DC115 of an PLC.
7.4.3.5. Display, Type
If you want to prevent the automatic switching at the 5% of
the maximum speed in the "
Display
" menu point, you can
select one of the three different display types with the
key and the
key.
"Automatic"
At the 5% point the display is switched from the position display to the speed
display. This bar display shows the speed in percent.
"Speed"
Only the speed is shown on the display. The bar display shows the speed in
percent.
"Position"
Only the position is shown on the display. The bar display does not show the speed,
but
it
displays
the
position
between
0%
and
100%
e.g. 0% = 0 Degree / 50% = 180 Degrees / 99% = 359 Degrees.
In addition to the three display types, you can also select
the desired display type through an input. The display type
has to be set to either
"Speed"
or
"Position"
, and the
number of the input has to be entered in the field behind.
When input is passive, the set display type is displayed.
When you supply a signal, the display changes from
"speed" to position or from "position" to "speed".
Press the
key to confirm your inputs and exit this
menu.
