I I I I I VLT parameter and SyncPos parameter
Basically there are 2 main parameter types: VLT
parameters and SyncPos option parameters.
The parameters of VLT parameter group 7.. are
both VLT parameters and SyncPos option
parameters.
VLT parameters except groups 7.. , 8.. and 9.. are
described in VLT5000 operating instruction
(MG.50.Ax.xx), this manual describes changes to
the VLT parameters including group 7.. and the
SyncPos option parameters.
VLT parameter groups 8.. and 9.. are only available
if a field bus option is installed and they are
described in the manuals covering these option
cards (see field bus option manual).
Factory settings of the parameter
All parameters has a default value called the fac-
tory setting. It is possible to reset the parameters
to factory setting:
VLT parameters can be reset to factory settings by
manual initialization of the VLT or by means of the
setup copy function (see in VLT5000 operating
instruction for further details).
SyncPos option parameters can be reset to factory
settings in menu "CONTROLLER" → "RESET" →
"PARAMETERS" or "CONTROLLER" → "RESET"
→ "COMPLETE". Deleting the entire memory in
menu "CONTROLLER" → "MEMORY" → "DELETE
EEPROM" will reset the parameters to factory
setting as well.
User parameter
The parameters 710 though 779 and 795 though
799 are user parameters which can be defined
and used in a SyncPos program.
The user parameters are defined in a SyncPos
program using the commands LINKAXPAR and
LINKGPAR, it is possible to specify a text which
will be displayed as parameter name in the LCP, a
minimum limit, a maximum limit and the way how
parameters will be executed:
0 = Online executes a changes to the parameter
value immediately after the input in display.
1 = Offline change means that a change to the
parameter value is activated when the OK key
is pressed.

VLT 5000 SyncPos option
An user parameter can be linked to a global option
card parameter or an axis option card parameter.
There are two types of global parameters:
• • • • • Predefined global parameters as for example
I_ERRCLR (107)
• • • • •
Free internal parameters which can be acces-
sed from the SyncPos program.
Parameters 130–229 are used for this pur-
pose.
Syntax examples:
/* Predefined global parameter */
LINKGPAR I_ERRCLR 710 " " 0 33 0
/* Free internal parameter */
LINKGPAR 132 711 "name" 0 100000 0
/* Axis parameter */
LINKAXPAR POSERR 712 "position error" 0
100000 0
Parameters 795 – 799 are read only parameters
which can be used for data read out on the LCP.
These parameters can be read out in display line 1
or 2. You can select which parameters from 795 to
799 are displayed at which position on the VLT
display in the VLT parameters 9, 10, 11 and 12:
User parameter 95 [31]
User parameter 96 [32]
User parameter 97 [33]
User parameter 98 [34]
User parameter 99 [35]
Parameter changes and storage
VLT parameters changed via the Local Control
Panel and SyncPos option parameter changed via
menu "CONTROLLER" → "PARAMETERS" →
"AXIS" are saved in an EEPROM and thus retained
at power down.
VLT parameters changed from the SyncPos appli-
cation program with the command SETVLT are only
stored in RAM and thus lost at power down.
SyncPos option parameters changed from the
SyncPos application program with the command
SET are only active while the application program
is running. SyncPos option parameters changed
from the application program can be saved in an
EEPROM and thus retained at power down by
means of the command SAVEPROM or press the
OK-key on the VLT display.
NB!
Please note that an EEPROM has limited
lifetime; but in can be reprogrammed
approximately 10000 times.
