Instructions Concerning The Setup Of An Own Application Software - OWIS PS35 Betriebsanleitung

14. Instructions Concerning the Setup of
an Own Application Software
Generally, a PS 35 application consists of an initialization part
which sets the necessary axis parameters for all for axes <n> to be
used and which switches on the axes, too. Furthermore, it consists
of a loop which executes a reference motion for all axes and of the
actual user program with all the functions required.

The initialization of the axes required is done with the INIT com-
mand at the simplest, if the parameters stored in the static RAM
are to be taken over. Otherwise, it is necessary to transfer the
parameters required, before sending the INIT command.

Subject to change without notice
If a reference motion for an axis is to be executed, reference mask
and reference polarity are to be set before. This is necessary only if
it has not already been done before or if no appropriate values
have been set for the standard settings. Then, the reference motion
is started.

A command processing time (interpretation time) of about 20 to
40 milliseconds has to be considered between two individual com-
mands sent to the PS 35. The control unit signals received can be
e.g. retrieved character by character every millisecond, until the
defined end-of-string identifier is received.
The use of the provided software tool OWISoft (including SDK and
DLL) facilitates the setup considerably, since frequently used com-
mand sequences are already recorded as functions or routines. Fur-
thermore, the necessary running time check is implemented, too.
