5.1 Describtion of the counter
Factory Setting
(Defaults):
Counter mode:
Prescaler:
Sets all the function codes to the factory settings,
i.e. all codes designated with *.
The following counter modes can be selected:
Unidirectional counting, adding or subtracting;
Unidirectional counting with directional input;
Differential counting, summation (totalizing) or
phase discriminator (quad) with single, double or quadruple evaluation.
The "Prescaler" is a multiplier. Each input pulse is multiplied by the adjusted factor. The display
shows integers only.
After a reset the counter is completely reset to 0; this also includes the non-visible value of < 1.
At a prescaler of >1 not all the values are selectable. If invalid Preset values are selected, the
counter will round them up to the next possible value.
Example: PSC cannot select (reach) Preset value 7. In this case, the counter automatically
changes the Preset value to 10).
If the Prescaler is changed, this may also affect the Preset values, which may have to be chan-
ged accordingly.
Adjusting range 0,0001 to 9,9999
The Prescaler is used, for example, to convert counter pulses into meaningful units, to adapt
the units of measurements (e.g. cm-pulses to inch-pulses), or to compensate for worn measu-
ring wheels.
