Autostart - Danfoss VLT 5000 Series Manual

"UPLOAD SOURCE"
All programs marked with '+' can be read out of
the control in source coding format and can be
filed on your PC for subsequent use.
Select the desired program and click on "UPLOAD
SOURCE". You can edit or duplicate the file for
other VLT's.
"AUTOSTART ON / OFF"
With Autostart you can mark a program that, in the
future, is to be started immediately after the VLT is
turned on. Select the desired program and click on
"AUTOSTART ON". The program selected will then
* * * * *
be marked with a .
If you want to remove an autostart command once
it has been assigned, click on "AUTOSTART OFF"
or simply mark another program.
If you want to have more than one program run
with autostart, use the parameter PRGPAR (102).
This allows you to determine which program should
be started after the conclusion of the program run
in autostart.
If nothing else has been determined in PRGPAR
(102) or I_PRGSTART (103), the program marked
with autostart will always be started.
A pre-set "AUTOSTART" has the following effect:
If no error is registered after a cold start (excep-
tions: tolerated position error is exceeded, end
switch error and SW end switch error) the corres-
ponding autostart program will be started.
If the autostart program is aborted by the user
(SyncPos) it will not start again unless a new cold
start is made. In this case no programs are started
due to inputs or PRGPAR (102).
If the autostart program is aborted due to an error
(since no ON ERROR routine was defined) or
ended normally, then the program subsequently
checks whether a start is planned through inputs
or if the parameter PRGPAR (102) is set. If so, then
the corresponding program is executed or the pro-
gram waits for the start input. If not, the autostart
program starts over again from the beginning. It
follows that:
One-time execution of the autostart program
If, in principle, you plan to start the programs via
the parameter PRGPAR (102) or via the inputs, then
the autostart program is only executed once (for
example for HOME functions).

Repeated execution of the autostart program
In all other instances the autostart program is
started repeatedly.
Thus, it is also possible to simply start a program
over again with an EXIT command. This is useful if,
in an error situation (ON ERROR), you do not wish
to continue with RETURN, but rather, for example,
wish to force a repeated home run. However, it is
important to make sure that an error has not
occurred (except for a tolerated position error is
exceeded, end switch errors and SW end switch
errors), since otherwise the autostart program will
not be started again.
Linking autostart programs
Naturally, starting via the parameter PRGPAR (102)
can also be used for linking purposes: After a
program has been started the program number
defined by PRGPAR (102) can be converted. Thus,
it is possible to determine which program is to be
executed next.
NB!
If no autostart program has been defined,
then it is not possible to start a program via
PRGPAR (102); this always requires a terminated
autostart program.
"DELETE ALL"
Click on "DELETE ALL" if you want to delete all
the programs in the VLT. Make sure beforehand
that you have saved the programs on the PC or in
the archive for safety reasons.
