2. Introduction
The counters of series ZD, ZA and ZR have been designed to close a gap with multiple counting
applications, which cannot be accomplished by the normal industrial electronic counters
available on the market.
A continual demand for increasing production speeds and higher precision at the same time
results in counting frequencies exceeding the conventional frequency range.
Particularly with fast running procedures it is most important to also have fast response of the
switching outputs or the analogue output.
Many applications require to evaluate the signals of two incremental measuring systems, and
to compare the results with respect to the sum or the difference or the ratio of the two
positions. This is e.g. necessary for calculation of diameters of winding rolls etc.
Still there exist applications where the use of traditional thumbwheel switches offers real
advantages compared to keypad and menu operations.
These are some of the reasons why the new counter series ZD, ZA and ZR have been designed.
•
This manual at first provides all
basic instructions
for operation of the
counter models presented in the previous chapter
•
For operation of relay outputs and thumbwheel switches (if applicable)
please observe the supplementary instructions given in the appendix
•
For easy PC setup and PC communication with ZD and ZA counters, please
use our “OS32” operator software (free of charge, download from our
homepage
www.motrona.com
•
Where you like to have free serial access to the unit by PLC or IPC or by a
remote operator terminal, please observe the serial protocol details
described in our separate manual “Serpro”
•
Subsequently the manual uses the expression ZD340 as a replacement for
all available models. However, statements are fully valid for the other
models too, except where especially remarked.
