4. Operating Modes of the Counter
For best survey, all parameters of the unit are arranged in 13 expedient groups, named
“F01” - “F13”. Depending on the application, only a few of these groups may be important,
while all other groups may be irrelevant for your specific application.
All details about configuration and function of the parameters can be founds in chapter 6.
Practical examples for settings are shown in chapter 7.
This section describes possible applications and operating modes of the unit.
The operation mode can be set under parameter group F02, parameter # F02.004.
It is possible to cycle the display between all reading modes shown in the following
function tables, by pressing one of the front keys or by using one of the control inputs
(you must have assigned the "display scrolling function" to one of the keys or the
inputs under menu F05 to activate the scrolling of the display).
LED L1 (red) and L2 (yellow) indicate which of the values is actually visible in display
L1 on: the speed of encoder 1 is displayed
L2 on: the speed of encoder 2 is displayed
L1 and L2 on: the combined value [encoder1]*[encoder2] is displayed.
LEDs shining continuously indicate: actual measuring value.
LEDs blinking slowly indicate: minimum value
(since last reset of the min/max memory).
LEDs blinking fast indicate: maximum value (since last reset of the min/max memory).
Scrolling of the display from one reading mode to another will not affect the function
of the preselection outputs K1 – K4
The analogue output (models SA) can be assigned to any of the readings accessible in
the display, by a special parameter. Scrolling of the display from one reading mode to
another will not affect the analogue output.
With all operating modes the evaluation of the input frequencies occurs fully
separately with use of individual scaling factors. Please observe that only integer
results after the scaling operations, but no decimal positions will appear in the
display. Where you like to display your result with decimals, please scale your value
correspondingly higher (by factor 10, 100 or 1000) and then use a decimal point to
receive the desired display value (see examples under 7.1)
With all encoders providing information about the direction of rotation
(e.g. quadrature encoders A/B/90°), the unit will also display a sign (positive with
A leading B and negative with B leading A). Preselection values can be set for
response to absolute values only (no consideration of the actual sign), or for response
to the signed value. With models SA the analogue output will also change the
+/- polarity in accordance with the actual sign.
All combinations [encoder1] * [encoder2] are calculated straightaway according to the
individual operating mode and the scaling factor of each channel. Please take care
that the results to combine are scaled with proper and compatible dimensions
(don't compare apples and oranges)
